  Cause:
  This warning message occurs during the activation or generation of an enhancement implementation (such as a Business Add-In (BAdI) or enhancement spot) when there is a type conflict between the enhancement structure defined in the enhancement implementation and the original structure or interface it is supposed to enhance.
  Specifically, the system detects that the data types or definitions of the fields in the enhancement structure do not match the expected types in the original structure/interface. This can happen if:
  
  The enhancement structure has been modified manually and its field types differ from the original.
  The original structure/interface has changed (e.g., after a system upgrade or patch), but the enhancement structure was not adjusted accordingly.
  There is a mismatch in the order, type, or length of fields between the enhancement structure and the original
