  The SAP error message CNV_PE_GEN137 indicates that the user does not have the necessary authorization to create a Data Dictionary (DDIC) table type in the SAP system. This error typically occurs during data migration or conversion processes, particularly when using tools like SAP's Data Migration Workbench or during custom development activities.
  Cause:
  The primary cause of this error is a lack of appropriate authorizations for the user executing the operation. Specifically, the user needs to have the necessary permissions to create or modify DDIC objects, which include table types, structures, and other related objects.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check the authorization check failure. This will provide insights into which specific authorization is missing.
  Alternatively, you can use transaction code SU01 to review the user's roles and authorizations.

  S_TABU_NAM: Authorization for table name maintenance
  
  
  You may need to work with your SAP security team to assign the correct roles or modify existing roles to include the necessary authorizations.
  
  
  
  Use a Different User:
  
  If the current user does not have the required authorizations and cannot be granted them, consider using a different user account that has the necessary permissions to perform the operation.
