• What is the cause and solution for SAP error message /PM0/3FWTG_GENERATOR227 - Class &1: error redefining method &2 ?

  The SAP error message /PM0/3FWTG_GENERATOR227 Class &1: error redefining method &2 typically indicates an issue related to method redefinition in ABAP classes. This error can occur when there is a problem with the inheritance or implementation of methods in a class hierarchy.
  Cause:
  
  Method Signature Mismatch: The method being redefined in a subclass does not match the signature of the method in the superclass. This includes differences in parameters, return types, or visibility (public, protected, private).
  Abstract Methods: If the method in the superclass is declared as abstract, it must be implemented in the subclass. If the implementation is missing or incorrect, this error can occur.
  Interface Implementation: If the class is implementing an interface and the method signature does not match the interface definition, this error can arise.
  Syntax Errors: There may be syntax errors in the method definition that prevent the class from being activated.
  
  Solution:
  
  Check Method Signatures: Ensure that the method signature in the subclass exactly matches the method signature in the superclass. This includes the name, parameters, and return type.
  Implement Abstract Methods: If the superclass has abstract methods, ensure that they are properly implemented in the subclass.
  Review Interface Methods: If the class implements an interface, verify that all methods defined in the interface are correctly implemented in the class.
  Syntax Review: Check for any syntax errors in the method definition. Ensure that the method is correctly defined according to ABAP syntax rules.
  Re-activate Classes: After making the necessary changes, re-activate the affected classes to ensure that the changes take effect.
