Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 114.37% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategy
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the fund normally invests at least 80% of its net assets, plus any borrowings for investment purposes, in fixed-income securities that, at the time of purchase, are rated below investment grade ("high yield" or "junk" bonds) or are the unrated equivalent as determined by Alcentra NY, LLC, the fund's sub-adviser. The fund's portfolio may include various types of fixed-income securities, such as corporate bonds and notes, mortgage-related securities, asset-backed securities, floating rate loans (limited to up to 20% of the fund's net assets) and other floating rate securities, zero coupon securities, convertible securities, preferred stock and other debt instruments of U.S. and foreign issuers.

In choosing securities for the fund, the fund's sub-adviser seeks to capture the higher yields offered by junk bonds, while managing credit risk and the volatility caused by interest rate movements. The fund's investment process involves a "top down" approach to security selection. The sub-adviser looks at a variety of factors when assessing a potential investment, including the state of the industry or sector, the company's financial strength, and the company's management. The sub-adviser also looks for companies that are underleveraged, have positive free cash flow, and are self-financing. There are no restrictions on the dollar-weighted average maturity or average effective duration of the fund's portfolio or on the maturities or durations of the individual fixed-income securities the fund may purchase. A bond's maturity is the length of time until the principal must be fully repaid with interest. Duration is an indication of an investment's "interest rate risk," or how sensitive a bond or the fund's portfolio may be to changes in interest rates.

The fund also may invest in collateralized debt obligations (CDOs), which are a type of asset-backed security and include collateralized bond obligations (CBOs) and collateralized loan obligations (CLOs) and other similarly structured securities. CDOs generally issue separate series or "tranches" which vary with respect to collateral, risk and yield. To enhance current income, the fund may engage in a series of purchase and sale contracts or forward roll transactions in which the fund sells a mortgage-related security, for example, to a financial institution and simultaneously agrees to purchase a similar security from the institution at a later date at an agreed upon price. The fund also may make forward commitments in which the fund agrees to buy or sell a security in the future at a price agreed upon today.

The fund typically will sell a security if the fund's sub-adviser believes it is overvalued from a valuation standpoint, another sector becomes relatively more attractive, and/or it expects fundamentals to deteriorate. In addition, at times, the fund may engage in active and frequent trading, which will increase portfolio turnover.

Principal Risks

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. It is not a complete investment program. The fund's share price fluctuates, sometimes dramatically, which means you could lose money.

BNY Mellon High Yield Fund | · Fixed-income market risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.

BNY Mellon High Yield Fund | · Interest rate risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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-related 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.

BNY Mellon High Yield Fund | · Credit risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.
BNY Mellon High Yield Fund | · High yield securities risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.
BNY Mellon High Yield Fund | · Mortgage-related securities risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.
BNY Mellon High Yield Fund | · Foreign investment risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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.

BNY Mellon High Yield Fund | · Market risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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. 

BNY Mellon High Yield Fund | · Liquidity risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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. 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 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.

BNY Mellon High Yield Fund | · Floating rate loan risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· 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 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. The floating rate loans in which the fund may invest typically will be below investment grade quality and, like other below investment grade securities, are inherently speculative. As a result, the risks associated with such floating rate loans are similar to the risks of below investment grade securities, although senior loans are typically senior and secured in contrast to other below investment grade securities, which are often subordinated and unsecured.

BNY Mellon High Yield Fund | · CDOs risk  
Risk/Return: rr_RiskReturnAbstract  
Risk [Text Block] rr_RiskTextBlock

· CDOs risk: The risks of an investment in a CDO, including a CBO or CLO, depend largely on the type of the collateral and the tranche of the CDO in which the fund invests. CDO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default, market anticipation of defaults, as well as aversion to CDO securities as an asset class. In addition to the normal risks associated with credit-related securities discussed elsewhere in this prospectus (e.g., interest rate risk and default risk), investments in CDOs may be more volatile, less liquid and more difficult to price than other types of investments.
BNY Mellon High Yield Fund | · Issuer risk
