How To Fix CNV21500040 - Structure of RELID <&1,&2> defined in DDIC, however exp. routine is macro

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV21500 - Messages for HR conversions basis

• Message number: 040

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

What causes this issue?

Structure of RELID <&v1&,&v2&> is defined in DDIC, however export
routine indicated in CNV_INDX_MACROS is not function module, which is
the preferred form of exporting 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'

• What is the cause and solution for SAP error message CNV21500040 - Structure of RELID <&1,&2> defined in DDIC, however exp. routine is macro ?

  The SAP error message CNV21500040 indicates a problem related to the structure definition in the Data Dictionary (DDIC) for a specific RELID (Release ID) during a data conversion or migration process. The error suggests that the structure is defined in the DDIC, but the expected routine is a macro, which can lead to inconsistencies or issues during the execution of the conversion program.
  Cause:
  
  Mismatch in Definitions: The error typically arises when there is a mismatch between the expected structure definition and the actual implementation in the DDIC. This can happen if the structure is defined as a standard structure but is being treated as a macro in the conversion routine.
  Incorrect Configuration: The configuration for the data migration or conversion process may not align with the definitions in the DDIC, leading to this error.
  Versioning Issues: If there are different versions of the data structures or routines being used, it can lead to discrepancies that trigger this error.
  
  Solution:
  
  Check Structure Definition: Verify the structure definition in the DDIC for the specified RELID. Ensure that it is correctly defined and matches the expected format for the conversion routine.
  Review Conversion Routines: Look into the conversion routines or macros being used. Ensure that they are correctly implemented and that there are no discrepancies between the expected and actual definitions.
  Update or Correct Configuration: If there are configuration settings that are incorrect, update them to align with the DDIC definitions. This may involve adjusting the settings in the migration tool or program.
  Consult Documentation: Refer to SAP documentation or notes related to the specific error message. There may be specific guidelines or patches available that address this issue.
  Testing: After making changes, conduct thorough testing to ensure that the error is resolved and that the data conversion process works as expected.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional context or solutions for this error message. SAP Notes often contain fixes or workarounds for known issues.
  Transaction Codes: Use transaction codes like SE11 (Data Dictionary) to check the structure definitions and SE80 (Object Navigator) to review the related programs and routines.
  Support: If the issue persists, consider reaching out to SAP support for assistance, providing them with detailed information about the error and the context in which it occurs.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
