How To Fix CNV_10020043 - Elem. rel. &1: Lengths of det. obj. &2 and conc./frag. obj. &3 differ

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10020 - Message class for package 10020

• Message number: 043

• Message text: Elem. rel. &1: Lengths of det. obj. &2 and conc./frag. obj. &3 differ

What causes this issue?

During the definition of elementary relationship &V1&, determination
object &V2& was assigned the concatenated/fragmented object &V3& (the
number in brackets is the length or number of characters).
The length of the determination object differs from the length of the
concatenated/fragmented object. These two values must be identical.

How to fix this error?

It is possible that an incorrect concatenated/fragmented object was
assigned. Correct the definition accordingly.
<ZH>Note:</>The length of a concatenated/fragmented object equals the
total length of all relevant fields. If one of the fields does not exist
in the given system (due to release dependencies), its length cannot be
calculated and considered.

• What is the cause and solution for SAP error message CNV_10020043 - Elem. rel. &1: Lengths of det. obj. &2 and conc./frag. obj. &3 differ ?

  The SAP error message CNV_10020043 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is a mismatch in the lengths of the fields between the detailed object and the corresponding consolidated or fragmented object.
  Cause:
  The error arises when:
  
  The length of a field in the detailed object (e.g., a source table or structure) does not match the length of the corresponding field in the consolidated or fragmented object (e.g., a target table or structure).
  This can happen due to differences in data types, field definitions, or changes in the data model between the source and target systems.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Objects: Check the error message for the specific objects involved (detailed object &2 and consolidated/fragmented object &3). This will help you pinpoint where the mismatch is occurring.
  
  
  Compare Field Definitions: 
  
  Go to the Data Dictionary (SE11) in SAP and look up the detailed object and the consolidated/fragmented object.
  Compare the field lengths and data types for the relevant fields.
  
  
  
  Adjust Field Lengths: 
  
  If the field lengths are indeed different, you may need to adjust the field lengths in the target object to match those in the source object, or vice versa, depending on the business requirements and data integrity considerations.
  If you are using a migration tool, ensure that the mapping configuration is correct.
  
  
  
  Check for Data Model Changes: If you are migrating from an older version of SAP to S/4HANA, review any changes in the data model that may have affected field lengths.
  
  
  Test the Migration: After making the necessary adjustments, run a test migration to ensure that the error is resolved and that data is being migrated correctly.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration process you are using, as there may be additional guidelines or considerations.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context.
  Migration Cockpit Documentation: Review the official SAP documentation for the Migration Cockpit, as it may contain specific instructions or best practices for handling data type and length mismatches.
  Community Forums: Consider searching or posting in SAP community forums or SAP Community Network (SCN) for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
