How To Fix CNV21500039 - Structure of RELID <&1,&2> defined in DDIC, however imp. routine is macro

CNV21500039 - Overview

• Message type: E = Error

• Message class: CNV21500 - Messages for HR conversions basis

• Message number: 039

• Message text: Structure of RELID <&1,&2> defined in DDIC, however imp. routine is macro

What causes this issue?

Structure of RELID <&v1&,&v2&> is defined in DDIC, however import
routine indicated in CNV_INDX_MACROS is not function module, which is
the preferred form of importing data for such RELIDs.
Search for relevant fields in this case is always done on the basis of
DDIC. This means, that our knowledge about RELID's structure is somehow
different from structure in DDIC - some of fields might not have been
found during the search process.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Please make sure you really don't want to use default function modules
for this RELID and check if the knowledge gathered in CNV_INDX_STRUC
table is correct.
Compare results of following query:
SELECT s~cluster_name s~relid s~versn s~tabst s~structure
s~struc_type
INTO CORRESPONDING FIELDS OF TABLE gt_cnv_indx_struc1
FROM cnv_indx_struc AS s JOIN t52relid AS t
ON
s~cluster_name = t~tabname AND
s~relid = t~relid AND
s~versn = t~version
WHERE
s~cluster_name = '&v1&' AND s~relid = '&v2&'.
and output of function module CNV_21500_T52RELID_DEFINED:
DATA lt_struct TYPE STANDARD TABLE OF cnv_indx_struc.
CALL FUNCTION 'CNV_21500_T52RELID_DEFINED'

CNV21500039 - Details

• The SAP error message CNV21500039 indicates that there is a mismatch between the structure definition in the Data Dictionary (DDIC) and the implementation routine that is expected to handle that structure. Specifically, the error suggests that the structure defined in the DDIC is not compatible with the implementation routine, which is defined as a macro.
  
  Cause:
  
  Mismatch in Definition: The structure RELID <&1,&2> is defined in the Data Dictionary, but the implementation routine that is supposed to process this structure is defined as a macro. This can lead to issues because macros do not have the same capabilities as function modules or methods in terms of handling complex data types.
  Incorrect Implementation: The implementation routine may not be correctly set up to handle the structure as expected, leading to this error.
  Versioning Issues: If there have been changes to the structure in the DDIC but the implementation routine has not been updated accordingly, this
