  Cause:
  The error message breaks down as follows:
  
  Elem. rel. &1: This refers to the element or relationship that is being processed.
  Spec. function module &2: This indicates the specific function module that is being called.
  TABLES parameter needs type &3: This part of the message specifies that the TABLES parameter in the function module is expected to have a certain data type, but the actual data type being passed does not match.
  
  The root cause of this error can be due to:
  
  Data Type Mismatch: The data being passed to the function module does not match the expected data type for the TABLES parameter.
  Incorrect Mapping: During the data migration process, the mapping of fields may not have been set up correctly, leading to incompatible data types.
