• What is the cause and solution for SAP error message CNV20551481 - Cluster &1 and cluster table &2 with separate program but same seq. no. ?

  The SAP error message CNV20551481 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that there are two cluster tables that are being processed with the same sequence number but are being handled by separate programs. This can lead to conflicts or inconsistencies in the data migration process.
  Cause:
  
  Duplicate Sequence Numbers: The error arises when two different cluster tables are assigned the same sequence number in the migration process. This can happen due to misconfiguration or incorrect mapping in the migration settings.
  Program Conflicts: If two different programs are trying to process the same data or tables simultaneously, it can lead to this error.
  Data Model Issues: There may be issues in the data model or the way the data is structured, leading to conflicts during the migration.
  
  Solution:
  
  Check Configuration: Review the migration configuration settings to ensure that each cluster table has a unique sequence number. Adjust the sequence numbers as necessary to avoid duplication.
  Review Mapping: Ensure that the mapping of the source and target tables is correctly defined and that there are no overlaps in the sequence numbers assigned to different tables.
  Sequential Processing: If possible, process the cluster tables sequentially rather than in parallel to avoid conflicts.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand the requirements and constraints regarding sequence numbers and cluster tables.
  Error Logs: Check the error logs for more detailed information about the error and any related issues that may provide further insights into the cause.
