    SAP Error Message:
    WER444 Type &1 is not a valid predefined type
    
    
    Cause: This error occurs when a program or configuration tries to use a type that is expected to be a predefined (standard) type in SAP, but the specified type name (&1) is not recognized as such. In other words, the system cannot find the predefined data type with the name provided. Common scenarios include: A typo or incorrect type name used in ABAP code or configuration. Using a type that is not defined or not available in the current SAP system/version. Attempting to use a type that is custom or user-defined but referenced as a predefined type. Issues in data element or domain definitions where the type is incorrectly specified.
    Solution: Check the Type Name: Verify the exact type name used in the code or configuration. Ensure it matches one of the standard predefined types in SAP (e.g., I, C, D, P, N, F, etc.). Correct Typo or Syntax: Correct any spelling
