• What is the cause and solution for SAP error message CNV_21539001 - Mapping not maintained for renaming attendance / absence type ?

  The SAP error message CNV_21539001 indicates that there is a mapping issue related to the renaming of attendance or absence types during a data migration or conversion process. This error typically arises in the context of SAP's data migration tools, particularly when using the SAP S/4HANA Migration Cockpit or similar tools.
  Cause:
  The error occurs when the system encounters an attendance or absence type that has not been properly mapped in the conversion settings. This can happen due to:
  
  Missing Mapping Entries: The mapping table for attendance/absence types does not contain an entry for the specific type being processed.
  Incorrect Configuration: The configuration for the migration might not have been set up correctly, leading to missing or incorrect mappings.
  Data Inconsistencies: The source data may contain types that do not exist in the target system or have not been defined in the mapping.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Mapping Configuration:
  
  Go to the relevant mapping configuration in the SAP system (usually found in the transaction code related to the migration tool you are using).
  Ensure that all attendance and absence types from the source system are correctly mapped to the corresponding types in the target system.
  
  
  
  Add Missing Mappings:
  
  If you identify any missing mappings, add them to the mapping table. This may involve creating new entries for the attendance/absence types that are not currently mapped.
  
  
  
  Review Source Data:
  
  Check the source data for any inconsistencies or unexpected values. Ensure that all attendance and absence types in the source data are valid and correspond to the types defined in the target system.
  
  
  
  Test the Migration:
  
  After making the necessary adjustments, run a test migration to verify that the error has been resolved and that the mapping works as expected.
