• What is the cause and solution for SAP error message /IWFND/CM_COS013 - Two Multi-Destination Composition BSOs found for object type '&1' ?

  The SAP error message /IWFND/CM_COS013 indicates that there are two Multi-Destination Composition Business Service Objects (BSOs) found for a specific object type, which can lead to ambiguity in the system. This error typically arises in the context of SAP Gateway and OData services when there are conflicting definitions or configurations.
  Cause:
  
  
  Duplicate Definitions: The most common cause of this error is the existence of multiple definitions for the same object type in the system. This can happen if:
  
  Two different developers created similar or identical service definitions.
  There are multiple versions of the same service that have not been properly managed or cleaned up.
  
  
  
  Configuration Issues: Sometimes, configuration issues in the SAP Gateway can lead to the system not being able to resolve which BSO to use.
  
  
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), it might lead to inconsistencies if the same object was modified in both systems.
  
  
  Solution:
  
  
  Identify Duplicates: 
  
  Use transaction code /IWFND/MAINT_SERVICE to check the list of registered services and identify any duplicates for the object type in question.
  Look for services that have the same name or similar configurations.
  
  
  
  Remove or Merge Duplicates: 
  
  If you find duplicate services, decide which one to keep and remove the other(s) using the appropriate transaction codes (e.g., /IWFND/MAINT_SERVICE to delete or deactivate the service).
  If necessary, merge the functionality of the duplicate services into a single service.
  
  
  
  Check Service Registration: 
  
  Ensure that the service is correctly registered and activated in the SAP Gateway. You can do this through the same transaction mentioned above.
  
  
  
  Clear Cache: 
  
  After making changes, clear the cache of the SAP Gateway to ensure that the changes take effect. You can do this using transaction code /IWFND/CACHE.
  
  
  
  Transport Management: 
  
  If the issue arose due to transport, ensure that the transport requests are correctly managed and that there are no conflicting changes in the target system.
