• What is the cause and solution for SAP error message 65331 - DCS-based class & cannot be used as copy reference ?

  The SAP error message 65331, which states "DCS-based class & cannot be used as copy reference," typically occurs when you are trying to create a copy of a class that is based on the Dynamic Class Structure (DCS) in the ABAP programming environment. DCS is a feature in SAP that allows for dynamic class definitions and is often used in scenarios involving polymorphism and dynamic behavior.
