  Cause:
  
  Table Configuration: The table in question may have been incorrectly configured or included in a list of tables that should not be present in the target system.
  Data Migration Process: During the data migration process, certain tables may be flagged for deletion or dropping, which can lead to this error if the system detects that the table is still in use or required.

  Solution:
  
  Review the Migration Plan: Check the migration plan or the configuration settings to ensure that the table in question is not supposed to be dropped. If it is needed, it should be removed from the list of tables marked for dropping.
  Check Dependencies: Investigate if there are any dependencies or references to the table in other parts of the system. If the table is still in use, it should not be included in the drop list.
  Adjust the Configuration: If the table is indeed required, adjust the configuration to exclude it from the drop list. This may involve modifying the migration settings or the data model.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion process you are undertaking. There may be specific guidelines or prerequisites that need to be followed.
