The following tables describe the fees and expenses that you may pay if you buy and hold shares of the Portfolio. Portfolio shares may be purchased only by or on behalf of separately managed account clients where Nuveen Asset Management, LLC has an agreement to serve as investment adviser or sub-adviser to the account with the separately managed account program sponsor or directly with the client. The fees and expenses in the following tables do not reflect any charges that are imposed by the separately managed accounts. If such charges were reflected, the fees and expenses would be higher than what is shown below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 27% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
The following example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then either redeem or do not redeem your shares at the end of a period. The example also assumes that your investment has a 5% return each year, that the Portfolio’s operating expenses remain the same and that the expense reimbursements continue to remain in place. The example does not reflect any charges that are imposed by the separately managed accounts. If such charges were reflected, the costs would be higher. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
Under normal circumstances, the Portfolio invests at least 80% of the sum of its net assets and the amount of any borrowings for investment purposes in fixed-income securities of emerging market issuers. The Portfolio primarily invests in a broad range of sovereign, quasi-sovereign and corporate fixed-income securities rated B- or better but may invest up to 30% of its assets in fixed-income securities rated lower than investment grade or unrated securities of comparable quality as determined by the Portfolio’s sub-adviser (securities commonly referred to as “high-yield” securities or “junk” bonds). The Portfolio may invest in fixed-income securities of any maturity or duration and Portfolio holdings may be denominated in U.S. dollars or non-U.S. dollar currencies, including emerging market currencies.
The Portfolio’s sub-adviser considers an “emerging market security” to be a security that is principally traded on a securities exchange of an emerging market or that is issued by an issuer that is located or has primary operations in an emerging market. The Portfolio generally defines an “emerging market” as any of the countries or markets represented in the Portfolio’s benchmark index, the J.P. Morgan Emerging Markets Bond Index Global Diversified, or any other country or market with similar emerging characteristics.
The Portfolio may invest in securities that have not been registered under the Securities Act of 1933, but that may be resold to qualified institutional buyers in accordance with the provisions of Rule 144A under the Securities Act of 1933 (“Rule 144A securities”).
The Portfolio may purchase and sell futures, options, swaps, forwards and other derivative instruments. The sub-adviser may use these derivatives in an attempt to manage market risk, currency risk, credit risk and interest rate risk, to manage the effective maturity or duration of securities in the portfolio or for speculative purposes in an effort to increase the Portfolio’s yield or to enhance returns. The use of a derivative is speculative if the sub-adviser is primarily seeking to enhance returns, rather than offset the risk of other positions.
Developed exclusively for use within separately managed accounts advised or sub-advised by Nuveen Asset Management, LLC, the Portfolio is a specialized fixed-income portfolio to be used in combination with selected individual securities to effectively model institutional-level investment strategies. The Portfolio enables certain Nuveen separately managed account investors to achieve greater diversification and return potential than might otherwise be achieved by investing in additional fixed-income classes, including those that have a lower credit quality and potentially higher yielding securities.

Nuveen Emerging Markets Debt Managed Accounts Portfolio | Active Management Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Active Management Risk—The Portfolio’s sub-adviser actively manages the Portfolio’s investments. Consequently, the Portfolio is subject to the risk that the investment techniques and risk analyses employed by the Portfolio’s sub-adviser may not produce the desired results. This could cause the Portfolio to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Call Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Call Risk—If, during periods of falling interest rates, an issuer exercises its right to prepay principal on its higher-yielding debt securities held by the Portfolio, the Portfolio may have to reinvest in securities with lower yields or higher risk of default, which may adversely impact the Portfolio’s performance.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Credit Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Credit Risk—Credit risk is the risk that an issuer or other obligated party of a debt security may be, or perceived (whether by market participants, rating agencies, pricing services or otherwise) to be, unable or unwilling to make interest and principal payments when due and the related risk that the value of a debt security may decline because of concerns about the issuer’s ability or willingness to make such payments.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Credit Spread Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Credit Spread Risk—Credit spread risk is the risk that credit spreads (i.e., the difference in yield between securities that is due to differences in their credit quality) may increase when the market believes that bonds generally have a greater risk of default. Increasing credit spreads may reduce the market values of the Portfolio’s debt securities. Credit spreads often increase more for lower rated and unrated securities than for investment grade securities. In addition, when credit spreads increase, reductions in market value will generally be greater for longer-maturity securities.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Currency Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Currency Risk—Changes in currency exchange rates will affect the value of non-U.S. securities, interest earned from such securities, gains and losses realized on the sale of such securities, and derivative transactions tied to such securities. A strong U.S. dollar relative to these other currencies will adversely affect the value of the Portfolio’s portfolio.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Cybersecurity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Cybersecurity Risk—Cybersecurity risk is the risk of an unauthorized breach and access to Portfolio assets, customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, its investment adviser or sub-adviser, custodian, transfer agent, distributor or other service provider, a financial intermediary or the issuers of securities held by the Portfolio to suffer a data breach, data corruption or lose operational functionality. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio, its service providers or the issuers of securities held by the Portfolio may adversely impact the Portfolio or its shareholders. Additionally, a cybersecurity breach could affect the issuers in which the Portfolio invests, which may cause the Portfolio’s investments to lose value.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Derivatives Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Derivatives Risk—The use of derivatives involves additional risks and transaction costs which could leave the Portfolio in a worse position than if it had not used these instruments. Derivative instruments can be used to acquire or to transfer the risk and returns of a security or other asset without buying or selling the security or asset, and the risks associated with investing in such derivatives may be different and greater than the risks associated with directly investing in the underlying securities and other instruments, including leverage risk, market risk, counterparty risk, liquidity risk, operational risk and legal risk. These instruments may entail investment exposures that are greater than their cost would suggest. As a result, a small investment in derivatives can result in losses that greatly exceed the original investment. Derivatives can be highly volatile, illiquid and difficult to value. An over-the-counter derivative transaction between the Portfolio and a counterparty that is not cleared through a central counterparty also involves the risk that a loss may be sustained as a result of the failure of the counterparty to the contract to make required payments. The payment obligation for a cleared derivative transaction is guaranteed by a central counterparty, which exposes the Portfolio to the creditworthiness of the central counterparty.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Emerging Markets Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Emerging Markets Risk—The risk of foreign investment often increases in countries with emerging markets or that are otherwise economically tied to emerging market countries. For example, these countries may have more unstable governments than developed countries and their economies may be based on only a few industries. Emerging market countries may also have less stringent regulation of accounting, auditing, financial reporting and recordkeeping requirements, which would affect the Portfolio’s ability to evaluate potential portfolio companies. As a result, there could be less information about issuers in emerging market countries, which could negatively affect the ability of the Portfolio’s sub-adviser to evaluate local companies or their potential impact on the Portfolio’s performance. Because their financial markets may be very small, prices of financial instruments in emerging market countries may be volatile and difficult to determine. Financial instruments of issuers in these countries may have lower overall liquidity than those of issuers in more developed countries. In addition, foreign investors such as the Portfolio are subject to a variety of special restrictions in many emerging market countries. Shareholder claims and regulatory actions that are available in the U.S. may be difficult or impossible to pursue in emerging market countries.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Foreign Investment Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Foreign Investment Risk—Non-U.S. issuers or U.S. issuers with significant non-U.S. operations may be subject to risks in addition to those of issuers located in or that principally operate in the United States as a result of, among other things, political, social and economic developments abroad, as well as armed conflicts and different legal, regulatory and tax environments. Foreign investments may also have lower liquidity and be more difficult to value than investments in U.S. issuers. To the extent the Portfolio invests a significant portion of its assets in the securities of companies in a single country or region, it may be more susceptible to adverse economic, market, political or regulatory events or conditions affecting that country or region. Foreign investments may also be subject to risk of loss because of more or less foreign government regulation, less public information, less stringent investor protections and less stringent accounting, corporate governance, financial reporting and disclosure standards.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | High Yield Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
High Yield Securities Risk—High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, and unrated securities of comparable quality are high risk investments that may cause income and principal losses for the Portfolio. They generally are considered to be speculative with respect to the ability to pay interest and repay principal, have greater credit risk, are less liquid, are more likely to experience a default and have more volatile prices than investment grade securities.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Income Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Income Risk—The Portfolio's income could decline during periods of falling interest rates or when the Portfolio experiences defaults on debt securities it holds.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Interest Rate Risks [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Interest Rate Risk—Interest rate risk is the risk that the value of the Portfolio’s fixed-rate securities will decline because of rising interest rates. Changing interest rates may have unpredictable effects on markets, result in heightened market volatility and detract from the Portfolio’s performance to the extent that it is exposed to such interest rates. Fixed-rate securities may be subject to a greater risk of rising interest rates than would normally be the case due to the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Higher periods of inflation could lead to government fiscal policies which raise interest rates. When interest rates change, the values of longer-duration fixed-rate securities usually change more than the values of shorter-duration fixed-rate securities. Conversely, fixed-rate securities with shorter durations or maturities will be less volatile but may provide lower returns than fixed-rate securities with longer durations or maturities. Rising interest rates also may lengthen the duration of securities with call features, since exercise of the call becomes less likely as interest rates rise, which in turn will make the securities more sensitive to changes in interest rates and result in even steeper price declines in the event of further interest rate increases. The Portfolio is also subject to the risk that the income generated by its investments may not keep pace with inflation. There is a risk that interest rates across the financial system may change, possibly significantly and/or rapidly. In general, changing interest rates, including rates that fall below zero, or a lack of market participants may lead to decreased liquidity and increased volatility in the fixed-rate or debt markets, making it more difficult for the Portfolio to sell fixed-rate investments. Changes in interest rates may also lead to an increase in Portfolio redemptions, which may result in higher portfolio turnover costs, thereby adversely affecting the Portfolio’s performance.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Market Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Market Risk—The market value of the Portfolio’s investments may go up or down, sometimes rapidly or unpredictably and for short or extended periods of time, due to the particular circumstances of individual issuers or due to general conditions impacting issuers more broadly. Global economies and financial markets have become highly interconnected, and thus economic, market or political conditions or events in one country or region might adversely impact the value of the Portfolio’s investments whether or not the Portfolio invests in such country or region. Events such as war, terrorism, natural and environmental disasters and the spread of infectious illnesses or other public health emergencies may have a severe negative impact on the global economy, could cause financial markets to experience extreme volatility and losses, and could result in the disruption of trading and the reduction of liquidity in many instruments. Additionally, as inflation increases, the value of the Portfolio’s assets can decline.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Market Liquidity Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Market Liquidity Risk—Reductions in trading activity or dealer inventories of securities such as bonds and preferred securities, which provide an indication of the ability of financial intermediaries to “make markets” in those securities, have the potential to decrease liquidity and increase price volatility in the markets in which the Portfolio invests, particularly during periods of economic or market stress. In addition, federal banking regulations may cause certain dealers to reduce their inventories of securities, which may further decrease the Portfolio’s ability to buy or sell securities. As a result of this decreased liquidity, the Portfolio may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on performance. If the Portfolio needed to sell large blocks of securities to meet shareholder redemption requests or to raise cash, those sales could further reduce the securities’ prices and hurt performance.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Quasi Sovereign Debt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Quasi-Sovereign Debt Risk— Quasi-sovereign securities are typically issued by companies that may receive financial support from a local government or in which the government owns a majority of the issuer’s voting shares. The governmental authority that controls the repayment of the debt may be unable or unwilling to make interest payments and/or repay the principal or to otherwise honor its obligations. If an issuer of quasi-sovereign debt defaults on payments of principal and/or interest, the Portfolio may have limited recourse against the issuer. A quasi-sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign currency reserves, the quasi-sovereign debtor’s policy toward international lenders, and the political constraints to which a quasi-sovereign debtor may be subject. During periods of economic uncertainty, the market prices of quasi-sovereign debt may be more volatile than prices of corporate debt, which may result in losses to the Portfolio. In the past, certain governments of emerging market countries have declared themselves unable to meet their financial obligations on a timely basis, which has resulted in losses for holders of quasi-sovereign debt.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Restricted Securities Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Restricted Securities Risk—The market for restricted securities, including Rule 144A securities, typically is less active than the market for publicly traded securities. Rule 144A securities and other securities exempt from registration under the Securities Act carry the risk that their liquidity may become impaired and the Portfolio may be unable to dispose of the securities promptly or at current market value.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Sovereign Debt Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Sovereign Debt Risk—Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt. This may be due to, for example, cash flow problems, insufficient
foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Unrated Security Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Unrated Security Risk—Unrated securities determined by the Portfolio’s sub-adviser to be of comparable quality to rated securities which the Portfolio may purchase may pay a higher interest rate than such rated securities and be subject to a greater risk of illiquidity or price changes. Less public information is typically available about unrated securities or issuers than rated securities or issuers.
Nuveen Emerging Markets Debt Managed Accounts Portfolio | Valuation Risk [Member]  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock
Valuation Risk—The sales price the Portfolio could receive for any particular debt security may differ from the Portfolio’s valuation of the investment, particularly for debt securities that trade in thin or volatile markets or that are valued using a fair value methodology. The debt securities in which the Portfolio invests typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including price quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Portfolio will be able to buy or sell a portfolio security at the price established by the pricing service, which could result in a gain or loss to the Portfolio. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Over certain time periods, such differences could materially impact the performance of the Portfolio, which may not be sustainable. Alternative pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Portfolio were to change pricing services, or if the Portfolio’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Portfolio’s net asset value.
