• What is the cause and solution for SAP error message WER167 - Type &1 of paramater &2 is not a valid DDIC type ?

  The SAP error message:
  WER167 Type &1 of parameter &2 is not a valid DDIC type
  
  
  Cause:
  This error occurs when a parameter in a function module, method, or any ABAP interface element is defined with a type that is not a valid Data Dictionary (DDIC) type. In other words, the type assigned to the parameter is either:
  
  A local type (defined in the program but not in the DDIC),
  A type that does not exist in the Data Dictionary,
  Or a type that is not allowed in the context where a DDIC type is mandatory.
  
  SAP requires certain interface parameters (especially in function modules, remote-enabled function modules, or BAPIs) to use only DDIC types to ensure consistency, transportability, and integration with other SAP components.
  
  
  Solution:
  
  
  Check the parameter type:
  
  Go to the interface (function module, method, or program) where the parameter is defined.
  Identify the parameter &2 mentioned in the error.
  Check the type &1 assigned to this parameter.
  
  
  
  Verify the type
