  Check Header Object: Ensure that the header object is created and exists in the system. You can do this by navigating to the relevant transaction or table where the header object is stored.

  Using the appropriate transaction code to establish the relationship.
  
  
  
  Review Configuration: If the issue persists, review the configuration settings related to the header and subobject relationships. This may involve checking customizing settings in the SAP system.
