• What is the cause and solution for SAP error message CNV_CMIS_A_20_FUNC021 - Counting number of table entries in destination & ?

  The SAP error message CNV_CMIS_A_20_FUNC021 typically occurs during data migration processes, particularly when using the SAP Conversion and Migration tools. This error indicates an issue with counting the number of entries in a specific table in the destination system.
  Cause:
  
  Table Locking: The table in the destination system may be locked by another process, preventing the counting operation from completing.
  Database Issues: There could be issues with the database connection or performance, leading to timeouts or failures in executing the count query.
  Insufficient Authorizations: The user executing the migration may not have the necessary authorizations to read from the destination table.
  Data Consistency Issues: There may be inconsistencies or corruption in the data that prevent the counting operation from being executed correctly.
  
  Solution:
  
  Check Table Locks: Use transaction codes like SM12 to check for any locks on the table in question. If locks are found, you may need to wait for the locking process to complete or resolve the lock.
  Database Performance: Ensure that the database is performing optimally. Check for any long-running queries or performance bottlenecks. You may need to consult your database administrator for assistance.
  User Authorizations: Verify that the user executing the migration has the necessary authorizations to access the destination table. You can check this in transaction SU53 or by reviewing the user's roles and authorizations.
  Data Consistency: Run consistency checks on the data in the destination system to ensure there are no issues. You can use transaction SE11 to check the table structure and data integrity.
  Retry the Operation: After addressing the above issues, retry the migration operation to see if the error persists.
  
  Related Information:
