• What is the cause and solution for SAP error message MDG_GN034 - No primary table can be determined for view &1 ?

  The SAP error message MDG_GN034: No primary table can be determined for view &1 typically occurs in the context of Master Data Governance (MDG) when the system is unable to identify a primary table for a specific view. This can happen for various reasons, often related to configuration or data model issues.
  Causes:
  
  Missing Configuration: The view in question may not be properly configured in the MDG data model. This could mean that the primary table has not been defined or linked correctly.
  Incorrect View Definition: The view might be incorrectly defined in the data model, leading to ambiguity about which table should be considered primary.
  Transport Issues: If the data model or configuration was recently transported from another system, there may be inconsistencies or missing elements.
  Data Model Changes: Changes made to the data model (like adding or removing fields or tables) without proper adjustments to the views can lead to this error.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the primary table, leading to this error.
  
  Solutions:
  
  
  Check Data Model Configuration:
  
  Go to the MDG data model configuration and verify that the view is correctly defined with a primary table.
  Ensure that all necessary fields and relationships are properly set up.
  
  
  
  Review View Definition:
  
  Check the view definition in the MDG configuration to ensure that it points to the correct primary table.
  If necessary, redefine the view to ensure it has a clear primary table.
  
  
  
  Transport Validation:
  
  If the issue arose after a transport, check the transport logs for any errors or warnings.
  Ensure that all necessary objects were transported correctly and that there are no missing dependencies.
  
  
  
  Check for Changes:
  
  Review any recent changes made to the data model or views. If changes were made, ensure that they are consistent and do not conflict with existing configurations.
  
  
  
  Authorization Check:
  
  Verify that the user encountering the error has the necessary authorizations to access the primary table associated with the view.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the relevant ABAP code to trace where the determination of the primary table is failing.
