• What is the cause and solution for SAP error message CNV_21521010 - Both old and new employee groups are initial ?

  The SAP error message CNV_21521010 indicates that both the old and new employee groups are set to initial (blank) during a data migration or conversion process. This typically occurs in the context of using SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  
  Data Mapping Issues: The error usually arises when there is a failure in mapping the old employee group to a new employee group during the migration process. If both fields are left blank, the system cannot determine which employee group to assign.
  Missing Configuration: The employee groups may not be properly configured in the target system, leading to the inability to assign any group.
  Data Quality Issues: The source data may have missing or incorrect values for employee groups, resulting in both fields being blank.
  
  Solution:
  
  Check Source Data: Review the source data to ensure that the old employee groups are populated correctly. If they are missing, you may need to correct the data in the source system before migration.
  Define Employee Groups: Ensure that the employee groups are defined in the target system. You can do this by checking the configuration in the SAP system (transaction code: SPRO).
  Mapping Configuration: In the migration tool, check the mapping configuration to ensure that the old employee groups are correctly mapped to the new employee groups. If necessary, create a mapping that assigns a default employee group if the old group is blank.
  Data Transformation: If you are using a transformation tool, ensure that the transformation logic correctly handles cases where the old employee group is blank. You may need to implement logic to assign a default value.
  Testing: After making the necessary changes, perform a test migration to verify that the issue has been resolved.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PA20 (Display HR Master Data) and PA30 (Maintain HR Master Data) to check employee group assignments.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on data migration issues.
  Documentation: Review the SAP documentation related to the migration process you are using, as it may provide insights into common pitfalls and best practices.
  
  By addressing the underlying causes and ensuring proper configuration and mapping, you should be able to resolve the error CNV_21521010 effectively.
