• What is the cause and solution for SAP error message HL630 - Main structure &1 not yet exported (no IWB_SHH_KEY) ?

  The SAP error message HL630, which states "Main structure &1 not yet exported (no IWB_SHH_KEY)," typically occurs in the context of SAP's Integration with other systems, particularly when dealing with the SAP Gateway and OData services. This error indicates that the main structure (or entity) has not been exported properly, which can prevent the system from processing requests related to that entity.
  Cause:
  
  Missing Export of Main Structure: The main structure (entity) that is being referenced has not been exported to the OData service. This can happen if the service has not been activated or if there are issues with the service definition.
  Incorrect Configuration: There may be configuration issues in the OData service or the underlying data model that prevent the main structure from being recognized.
  Transport Issues: If the OData service was recently transported from one system to another, there may be inconsistencies or missing components in the target system.
  Development Errors: Errors in the ABAP code or the service definition can lead to this issue, especially if the service was customized.
  
  Solution:
  
  
  Check OData Service Activation:
  
  Go to the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE).
  Ensure that the OData service is activated. If it is not, activate it.
  
  
  
  Review Service Definition:
  
  Open the service definition in the Service Builder and check if the main structure is correctly defined and exported.
  Ensure that the entity set is properly configured and that all necessary fields are included.
  
  
  
  Check for Missing Components:
  
  If the service was transported, verify that all necessary components (like data elements, structures, etc.) are present in the target system.
  Use transaction SE80 or SE11 to check the existence of the main structure.
  
  
  
  Debugging:
  
  If you have access to the ABAP code, you can debug the service to identify where the export is failing.
  Look for any custom logic that might be preventing the export of the main structure.
  
  
  
  Rebuild the Service:
  
  If the issue persists, consider rebuilding the OData service. This can be done by regenerating the service in the Service Builder.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
