  The SAP error message CNV_CMIS_A_20159 indicates that there is an issue with the table class being used in a conversion or migration process. Specifically, the error states that only 'TRANSP' (transparent tables) or 'POOL' (pool tables) table classes are allowed for the operation being performed.
  Cause:

  A table that is not classified as 'TRANSP' or 'POOL' is being referenced in a context where only these types are permitted.

  Solution:
  To resolve this error, you can take the following steps:

  Adjust Migration Logic: If you are using a migration tool or custom code, ensure that the logic does not attempt to process tables that are not allowed. You may need to add checks or filters to exclude unsupported table types.
  
  
  Consult Documentation: Review the documentation for the specific migration or conversion process you are using. There may be additional constraints or requirements that need to be adhered to.
