Investment Risks - BNY Mellon Short Term Income Fund	Jul. 31, 2024
Risk Lose Money [Member]
Prospectus [Line Items]
Risk [Text Block]	The fund's share price fluctuates, sometimes dramatically, which means you could lose money.
Risk Not Insured [Member]
Prospectus [Line Items]
Risk [Text Block]	An investment in the fund is not a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other government agency.
Fixed-income market risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Fixed-income market risk: The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in fund redemption requests, including requests from shareholders who may own a significant percentage of the fund's shares, which may be triggered by market turmoil or an increase in interest rates, could cause the fund to sell its holdings at a loss or at undesirable prices and adversely affect the fund's share price and increase the fund's liquidity risk, fund expenses and/or taxable distributions. Federal Reserve policy in response to market conditions, including with respect to interest rates, may adversely affect the value, volatility and liquidity of dividend and interest paying securities. Policy and legislative changes worldwide are affecting many aspects of financial regulation. The impact of these changes on the markets and the practical implications for market participants may not be fully known for some time.
Interest Rate Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Interest rate risk: Prices of bonds and other fixed rate fixed-income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed-income securities and, accordingly, will cause the value of the fund's investments in these securities to decline. A wide variety of market factors can cause interest rates to rise, including central bank monetary policy, rising inflation and changes in general economic conditions. It is difficult to predict the pace at which central banks or monetary authorities may increase (or decrease) interest rates or the timing, frequency, or magnitude of such changes. During periods of very low interest rates, which occur from time to time due to market forces or actions of governments and/or their central banks, including the Board of Governors of the Federal Reserve System in the U.S., the fund may be subject to a greater risk of principal decline from rising interest rates. When interest rates fall, the fund's investments in new securities may be at lower yields and may reduce the fund's income. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and may detract from fund performance. The magnitude of these fluctuations in the market price of fixed-income securities is generally greater for securities with longer effective maturities and durations because such instruments do not mature, reset interest rates or become callable for longer periods of time. Unlike investment grade bonds, however, the prices of high yield ("junk") bonds may fluctuate unpredictably and not necessarily inversely with changes in interest rates. Interest rate changes may have different effects on the values of mortgage-backed securities because of prepayment and extension risks. In addition, the rates on floating rate instruments adjust periodically with changes in market interest rates. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of floating rate loans and other floating rate securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates.
Credit Risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Credit risk: Failure of an issuer of a security to make timely interest or principal payments when due, or a decline or perception of a decline in the credit quality of the security, can cause the security's price to fall. The lower a security's credit rating, the greater the chance that the issuer of the security will default or fail to meet its payment obligations.
High yield securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● High yield securities risk: High yield ("junk") securities involve greater credit risk, including the risk of default, than investment grade securities, and are considered predominantly speculative with respect to the issuer's ability to make principal and interest payments. These securities are especially sensitive to adverse changes in general economic conditions, to changes in the financial condition of their issuers and to price fluctuation in response to changes in interest rates. During periods of economic downturn or rising interest rates, issuers of below investment grade securities may experience financial stress that could adversely affect their ability to make payments of principal and interest and increase the possibility of default.
Liquidity risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Liquidity risk: When there is little or no active trading market for specific types of securities, it can become more difficult to sell the securities in a timely manner at or near their perceived value. In such a market, the value of such securities and the fund's share price may fall dramatically. The secondary market for certain municipal bonds tends to be less well developed or liquid than many other securities markets, which may adversely affect the fund's ability to sell such municipal bonds at attractive prices. Investments that are illiquid or that trade in lower volumes may be more difficult to value. The market for below investment grade securities may be less liquid and therefore these securities may be harder to value or sell at an acceptable price, especially during times of market volatility or decline. Investments in foreign securities, particularly those of issuers located in emerging markets, tend to have greater exposure to liquidity risk than domestic securities. No active trading market may exist for some of the floating rate loans in which the fund invests and certain loans may be subject to restrictions on resale. Because some floating rate loans that the fund invests in may have a more limited secondary market, liquidity risk is more pronounced for the fund than for mutual funds that invest primarily in other types of fixed-income instruments or equity securities.
Foreign investment risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Foreign investment risk: To the extent the fund invests in foreign securities, the fund's performance will be influenced by political, social and economic factors affecting investments in foreign issuers. Special risks associated with investments in foreign issuers include exposure to currency fluctuations, less liquidity, less developed or less efficient trading markets, lack of comprehensive company information, political and economic instability and differing auditing and legal standards. Investments denominated in foreign currencies are subject to the risk that such currencies will decline in value relative to the U.S. dollar and affect the value of these investments held by the fund.
Emerging market risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Emerging market risk: The securities of issuers located or doing substantial business in emerging market countries tend to be more volatile and less liquid than the securities of issuers located in countries with more mature economies. Emerging markets generally have less diverse and less mature economic structures and less stable political systems than those of developed countries. Investments in these countries may be subject to political, economic, legal, market and currency risks. Special risks associated with investments in emerging market issuers may include a lack of publicly available information, a lack of uniform disclosure, accounting and financial reporting and recordkeeping standards and limited investor protections applicable in developed economies. The risks also may include unpredictable political and economic policies, the imposition of capital controls and/or foreign investment limitations by a country, nationalization of businesses and the imposition of sanctions or restrictions on certain investments by other countries, such as the United States.
Inflation-indexed security risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Inflation-indexed security risk: Interest payments on inflation-indexed securities can be unpredictable and will vary as the principal and/or interest is periodically adjusted based on the rate of inflation. If the index measuring inflation falls, the interest payable on these securities will be reduced. The U.S. Treasury has guaranteed that in the event of a drop in prices, it would repay the par amount of its inflation-indexed securities. Inflation-indexed securities issued by corporations generally do not guarantee repayment of principal. Any increase in the principal amount of an inflation-indexed security will be considered taxable ordinary income, even though investors do not receive their principal until maturity. As a result, the fund may be required to make annual distributions to shareholders that exceed the cash the fund received, which may cause the fund to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation-indexed security is adjusted downward due to deflation, amounts previously distributed may be characterized in some circumstances as a return of capital.
Government securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Government securities risk: Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some obligations are backed only by the credit of the issuing agency or instrumentality, and in some cases there may be some risk of default by the issuer. Any guarantee by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply to the market value of such security or to shares of the fund itself.
Municipal securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Municipal securities risk: The amount of public information available about municipal securities is generally less than that for corporate equities or bonds. Special factors, such as legislative changes, and state and local economic and business developments, may adversely affect the yield and/or value of the fund's investments in municipal securities. Other factors include the general conditions of the municipal securities market, the size of the particular offering, the maturity of the obligation and the rating of the issue. Changes in economic, business or political conditions relating to a particular municipal project, municipality, or state, territory or possession of the United States in which the fund invests may have an impact on the fund's share price. Any credit impairment could adversely impact the value of their bonds, which could negatively impact the performance of the fund.
Mortgage-related securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Mortgage-related securities risk: Mortgage-related securities are subject to credit, prepayment and extension risk, and may be more volatile, less liquid and more difficult to price accurately than more traditional debt securities. The fund is subject to the credit risk associated with these securities, including the market's perception of the creditworthiness of the issuing federal agency, as well as the credit quality of the underlying assets. Although certain mortgage-related securities are guaranteed as to the timely payment of interest and principal by a third party (such as a U.S. government agency or instrumentality with respect to government-related mortgage securities) the market prices for such securities are not guaranteed and will fluctuate. As with other interest-bearing securities, the prices of certain mortgage-related securities are inversely affected by changes in interest rates. However, although the value of a mortgage-related security may decline when interest rates rise, the converse is not necessarily true, since in periods of declining interest rates the mortgages underlying the security are more likely to be prepaid causing the fund to purchase new securities at current market rates, which usually will be lower. The loss of higher yielding underlying mortgages and the reinvestment of proceeds at lower interest rates, known as prepayment risk, can reduce the fund's potential price gain in response to falling interest rates, reduce the fund's yield and/or cause the fund's share price to fall. When interest rates rise, the effective duration of the fund's mortgage-related and other asset-backed securities may lengthen due to a drop in prepayments of the underlying mortgages or other assets. This is known as extension risk and would increase the fund's sensitivity to rising interest rates and its potential for price declines.
Asset-backed securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Asset-backed securities risk: Asset-backed securities are subject to credit, prepayment and extension risk, and may be more volatile, less liquid and more difficult to price accurately than more traditional debt securities. General downturns in the economy could cause the value of asset-backed securities to fall. Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans.
Convertible securities risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Convertible securities risk: Convertible securities may be converted at either a stated price or stated rate into underlying shares of common stock. Convertible securities generally are subordinated to other similar but non-convertible securities of the same issuer. Although to a lesser extent than with fixed-income securities, the market value of convertible securities tends to decline as interest rates increase. In addition, because of the conversion feature, the market value of convertible securities tends to vary with fluctuations in the market value of the underlying common stock.
Preferred stock risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Preferred stock risk: Preferred stock is a class of a capital stock that typically pays dividends at a specified rate. Preferred stock is generally senior to common stock, but subordinate to debt securities, with respect to the payment of dividends and on liquidation of the issuer. The market value of preferred stock generally decreases when interest rates rise and is also affected by the issuer's ability to make payments on the preferred stock.
Floating rate loan risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Floating rate loan risk: Unlike publicly traded common stocks which trade on national exchanges, there is no central market or exchange for loans to trade. Loans trade in an over-the-counter market, and confirmation and settlement, which are effected through standardized procedures and documentation, may take significantly longer than seven days to complete. The secondary market for floating rate loans also may be subject to irregular trading activity and wide bid/ask spreads. The lack of an active trading market for certain floating rate loans may impair the ability of the fund to realize full value in the event of the need to sell a floating rate loan and may make it difficult to value such loans. There may be less readily available, reliable information about certain floating rate loans than is the case for many other types of securities, and the fund's portfolio managers may be required to rely primarily on their own evaluation of a borrower's credit quality rather than on any available independent sources. The value of collateral, if any, securing a floating rate loan can decline, and may be insufficient to meet the issuer's obligations in the event of non-payment of scheduled interest or principal or may be difficult to readily liquidate. In the event of the bankruptcy of a borrower, the fund could experience delays or limitations imposed by bankruptcy or other insolvency laws with respect to its ability to realize the benefits of the collateral securing a loan.
Derivatives risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Derivatives risk: A small investment in derivatives could have a potentially large impact on the fund's performance. The use of derivatives involves risks different from, or possibly greater than, the risks associated with investing directly in the underlying assets, and the fund's use of derivatives may result in losses to the fund. Derivatives in which the fund may invest can be highly volatile, illiquid and difficult to value, and there is the risk that changes in the value of a derivative held by the fund will not correlate with the underlying assets or the fund's other investments in the manner intended. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment, and involve greater risks than the underlying assets because, in addition to general market risks, they are subject to liquidity risk, credit and counterparty risk (failure of the counterparty to the derivatives transaction to honor its obligation) and pricing risk (risk that the derivative cannot or will not be accurately valued).
Portfolio turnover risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Portfolio turnover risk: The fund may engage in short-term trading, which could produce higher transaction costs and taxable distributions, and lower the fund's after-tax performance.
Issuer risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Issuer risk: A security's market value may decline for a number of reasons which directly relate to the issuer, or to factors that affect the issuer's industry.
Market risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Market risk: The value of the securities in which the fund invests may be affected by political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed-income markets may negatively affect many issuers, which could adversely affect the fund. Global economies and financial markets are becoming increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies world-wide.
Management risk [Member]
Prospectus [Line Items]
Risk [Text Block]	● Management risk: The investment process used by the fund's sub-adviser could fail to achieve the fund's investment goal and cause your fund investment to lose value.
