  The SAP error message CNV_CDMC_CA120 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that the system encountered an issue while trying to determine if a specific database table is empty.
  Cause:
  The error can be caused by several factors, including:
  
  Table Locking: The table in question may be locked by another process, preventing the system from checking its contents.
  Authorization Issues: The user executing the migration may not have the necessary authorizations to access the table or perform the check.
  Database Connectivity Issues: There may be issues with the database connection, leading to failures in executing the query to check the table's status.
  Corrupted Table: The table might be corrupted or have inconsistencies that prevent the system from determining its status.
  Configuration Issues: There may be misconfigurations in the migration settings or parameters that lead to this error.
  
  Solution:
  To resolve the CNV_CDMC_CA120 error, you can take the following steps:
