  Cause
  This warning occurs when you try to pass a parameter to a function module, method, or subroutine, but the data type of the actual parameter (the expression you are passing) does not match the expected data type of the formal parameter defined in the interface.
  Common causes include:
  
  Passing a field symbol or data object of an incompatible type.
  Passing a structure or table where a simple data type is expected, or vice versa.
  Passing a data object with a different length or type (e.g., passing a string where an integer is expected).
  Using incompatible types in CALL FUNCTION, METHOD calls, or PERFORM statements with USING/CHANGING parameters.
  
  
  Solution
  
  
  Check the parameter types:
  
  Verify the data type of the actual parameter you are passing.
  Compare it with the expected data type of the formal parameter
