  Error Message: W8181 - Data type incompatible
  
  
  Cause:
  This warning or error occurs when there is an attempt to assign or move data between two fields or variables whose data types are incompatible. For example:
  
  Assigning a character field to a numeric field without proper conversion.
  Moving data between fields of different lengths or incompatible types (e.g., integer to string without conversion).
  Using incompatible data types in operations, function calls, or parameter passing.
  
  In ABAP, data type compatibility is strict, and implicit conversions are limited. The system raises this message to prevent data corruption or runtime errors.
  
  Typical Scenarios:
  
  Assigning a field of type CHAR to a field of type NUMC or INT directly.
  Passing parameters to function modules or methods where the expected data type differs from the actual parameter.
  Using MOVE or = operator between incompatible types.
  Field symbols or data references pointing to incompatible types.
