• What is the cause and solution for SAP error message /IWFND/CM_MGW087 - Metadata Routing is based on IWF customizing (GSDO Group based) ?

  The SAP error message /IWFND/CM_MGW087 typically indicates an issue with the metadata routing in the SAP Gateway framework, specifically related to the configuration of the IWF (Integrated Web Framework) customizing settings. This error often arises when the system is unable to determine the correct service or metadata based on the provided request, particularly when using Group-based Service Definition Objects (GSDO).
  Cause:
  
  Incorrect Configuration: The error may occur if the service is not properly configured in the SAP Gateway. This includes issues with the service registration or the service definition.
  Missing or Incorrect GSDO: If the Group-based Service Definition Object (GSDO) is missing or incorrectly defined, the system may not be able to route the request correctly.
  Authorization Issues: Sometimes, the user may not have the necessary authorizations to access the service, leading to routing failures.
  Service Activation: The service might not be activated in the SAP Gateway, which can prevent proper routing.
  Metadata Issues: Problems with the metadata itself, such as missing or incorrect entity sets, can also lead to this error.
  
  Solution:
  
  
  Check Service Registration:
  
  Go to the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE) and ensure that the service is registered and activated.
  Verify that the service is correctly linked to the appropriate GSDO.
  
  
  
  Review GSDO Configuration:
  
  Check the configuration of the Group-based Service Definition Object (GSDO) to ensure it is set up correctly.
  Ensure that all necessary services are included in the GSDO.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to access the service. This can be done by checking the roles assigned to the user.
  
  
  
  Activate Services:
  
  If the service is not activated, activate it using the Service Maintenance transaction.
  
  
  
  Review Metadata:
  
  Check the metadata of the service to ensure that all entity sets and properties are correctly defined.
  You can use the transaction /IWFND/ERROR_LOG to check for any additional error messages that might provide more context.
