• What is the cause and solution for SAP error message CNV_21522013 - Possible merge of employee subgroups &1 and &2 ?

  The SAP error message CNV_21522013 indicates a potential issue during a data migration or conversion process, specifically related to the merging of employee subgroups. This error typically arises when the system detects that two employee subgroups, identified by the placeholders &1 and &2, may be merged, which could lead to data inconsistencies or conflicts.
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Duplicate Employee Subgroups: The employee subgroups being processed may have overlapping or conflicting definitions, which can lead to ambiguity in how employee data is categorized.
  Configuration Issues: There may be configuration settings in the SAP system that allow for the merging of subgroups, but the system has detected that this could lead to issues.
  Data Migration Process: During a data migration (e.g., from an older system to SAP S/4HANA), the mapping of employee subgroups may not have been set up correctly, leading to potential conflicts.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Employee Subgroup Definitions:
  
  Check the definitions of the employee subgroups involved (subgroup &1 and subgroup &2) to understand their configurations and any overlaps.
  Ensure that the subgroups are distinct and do not have conflicting attributes.
  
  
  
  Adjust Configuration:
  
  If the subgroups are intended to be merged, you may need to adjust the configuration settings in the SAP system to allow for this merge.
  If they should remain separate, ensure that the data migration or conversion process reflects this distinction.
  
  
  
  Data Mapping Review:
  
  Review the data mapping in the migration process to ensure that employee subgroups are correctly assigned and that there are no unintended overlaps.
  Make necessary adjustments to the mapping to prevent conflicts.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or best practices for handling employee subgroups.
  
  
  
  Testing:
  
  After making adjustments, conduct thorough testing to ensure that the changes resolve the error and that employee data is correctly categorized.
  
  
  
  Seek Expert Assistance:
  
  If the issue persists, consider reaching out to SAP support or consulting with an SAP expert who specializes in data migration and employee management.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like PA30 (Maintain HR Master Data) or SPRO (Customizing) to review and adjust employee subgroup settings.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling employee subgroup merges.
  Migration Tools: If you are using SAP's migration tools (like the SAP S/4HANA Migration Cockpit), ensure that you are following the recommended procedures for handling employee data.
