• What is the cause and solution for SAP error message /UI2/FDM306 - Target Mapping &1&2: Could not read ?

  The SAP error message /UI2/FDM306 Target Mapping &1&2: Could not read typically indicates an issue with the target mapping configuration in the SAP Fiori Launchpad. This error can occur for various reasons, including missing or incorrect target mappings, issues with the underlying OData services, or problems with the configuration of the Fiori Launchpad itself.
  Causes:
  
  Missing Target Mapping: The target mapping for the specified application is not defined in the Fiori Launchpad configuration.
  Incorrect Target Mapping: The target mapping exists but is incorrectly configured (e.g., wrong semantic object or action).
  Authorization Issues: The user may not have the necessary authorizations to access the target mapping.
  OData Service Issues: The OData service associated with the target mapping may not be activated or may have errors.
  Transport Issues: If the configuration was transported from another system, there may be inconsistencies or missing objects.
  
  Solutions:
  
  
  Check Target Mapping:
  
  Go to the Fiori Launchpad Designer and verify that the target mapping exists for the application you are trying to access.
  Ensure that the semantic object and action are correctly defined.
  
  
  
  Verify OData Service:
  
  Check if the OData service associated with the target mapping is activated in the SAP Gateway (transaction /IWFND/MAINT_SERVICE).
  Test the OData service to ensure it is functioning correctly.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary roles and authorizations to access the target mapping and the associated OData service.
  
  
  
  Check Configuration:
  
  Review the configuration in the Fiori Launchpad to ensure that all necessary components are correctly set up.
  If the target mapping was recently changed, ensure that the changes were saved and activated.
  
  
  
  Transport Consistency:
  
  If the issue arose after a transport, check for any missing objects or inconsistencies in the target mapping configuration.
  
  
  
  Debugging:
  
  If you have access to the backend, you can use transaction SLG1 to check for logs related to the error, which may provide more context.
