SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_20600_CHECK - Messages for Check classes

• Message number: 052

• Message text: Temporary dupl. possible due to mapping of company codes for no. assignm.

What causes this issue?

<DS:TX.CNV_MBT_TEMP_DUPLICATES>Temporary duplicates</> possible due to
mapping of the company codes for number assignment.
Example: Company code for number assignment A is renamed into B
(mapping: A -> B). Company code for number assignment B is renamed into
C (mapping: B -> C). In this case, temporary duplicates may occur in the
database if company code for number assignment A is converted at a point
in time when company code for number assignment B has not yet been
converted. If temporary duplicates are likely to occur, the conversion
programs must be generated in a different way.

• What is the cause and solution for SAP error message CNV_20600_CHECK052 - Temporary dupl. possible due to mapping of company codes for no. assignm. ?

  The SAP error message CNV_20600_CHECK052 indicates that there is a potential issue with duplicate number assignments due to the mapping of company codes in the context of a data migration or conversion process. This error typically arises during the use of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  The error is caused by the following factors:
  
  Duplicate Number Ranges: The system has detected that there are overlapping or duplicate number ranges for different company codes. This can happen if multiple company codes are configured to use the same number range for document numbers, customer numbers, vendor numbers, etc.
  Mapping Issues: During the mapping of company codes, if the same number range is assigned to multiple company codes, it can lead to potential duplicates when documents are created or processed.
  Configuration Errors: Incorrect configuration in the number range settings for the company codes can also lead to this error.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Review Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the number range objects related to the company codes in question.
  Ensure that each company code has a unique number range assigned to it.
  
  
  
  Adjust Mapping:
  
  If you are using a migration tool, review the mapping of company codes and ensure that each company code is mapped to a distinct number range.
  If necessary, adjust the mapping to avoid overlaps.
  
  
  
  Create New Number Ranges:
  
  If you find that company codes are sharing number ranges, consider creating new number ranges for the affected company codes to eliminate the possibility of duplicates.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, perform a test run of the migration or conversion process to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using for additional guidance on handling number range issues.
