  The SAP error message USMD1403 indicates that there is an issue with activating a Data Dictionary (DDIC) table type in the context of a data model. This error typically arises in the SAP Master Data Governance (MDG) environment when there are inconsistencies or issues with the underlying data model or the table type definition.
  Cause:
  
  Inconsistent Table Definition: The table type may have inconsistencies in its definition, such as missing fields or incorrect data types.
  Dependencies: There may be dependencies on other objects (like structures or tables) that are not activated or have errors.
  Transport Issues: If the table type was transported from another system, there may be issues related to the transport that prevent activation.
  Authorization Issues: Lack of proper authorizations to activate the DDIC objects can also lead to this error.

  Check Table Type Definition: Review the definition of the DDIC table type in transaction SE11. Ensure that all fields are correctly defined and that there are no inconsistencies.

  Transport Check: If the table type was transported, check the transport logs for any errors. You may need to re-transport or correct any issues.
  Authorization Check: Ensure that you have the necessary authorizations to activate DDIC objects. Consult with your SAP security team if needed.
