• What is the cause and solution for SAP error message SCRL604 - Type properties of param. &1 of method &2 were changed in an incomp. way. ?

  The SAP error message SCRL604 indicates that there is an inconsistency in the type properties of a parameter in a method. This typically occurs when the method's parameter type has been changed in a way that is not compatible with its previous definition. This can happen during development when changes are made to the method signature or the data types of the parameters without proper adjustments in all places where the method is called.
  Cause:
  
  Inconsistent Changes: The parameter type of a method has been changed in a way that is not compatible with its previous definition. For example, changing a parameter from a simple data type to a complex structure or vice versa.
  Multiple Implementations: If the method is implemented in multiple places (like in different classes or interfaces), and the changes were not uniformly applied across all implementations.
  Inheritance Issues: If the method is part of a class hierarchy, changes in the base class may not be compatible with derived classes.
  
  Solution:
  
  Review Changes: Go back to the method definition and review the changes made to the parameter types. Ensure that all references to this method are updated accordingly.
  Check Implementations: If the method is implemented in multiple places, ensure that all implementations are consistent with the new parameter types.
  Recompile: After making the necessary changes, recompile the affected classes or programs to ensure that all references are updated.
  Use Consistent Types: Ensure that the types used in method calls match the new parameter types defined in the method signature.
  Check for Inheritance Issues: If the method is part of a class hierarchy, ensure that any overridden methods in derived classes are also updated to match the new parameter types.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Review the SAP documentation for guidelines on method parameter changes and best practices for maintaining consistency in method signatures.
  Development Guidelines: Follow best practices in ABAP development to avoid such inconsistencies, such as using consistent naming conventions and documenting changes thoroughly.
  
  By addressing the inconsistencies and ensuring that all method calls and implementations are aligned with the new parameter definitions, you should be able to resolve the SCRL604 error.
