Functionality
If necessary, the relationships created locally usingBAPI_REL_CREATERELATION and BAPI_REL_MASSCREATERELATION are alsocreated in remote systems. This is the case if one of the linkedobjects is in a remote system and the relationship has been marked asREMOTE when created in the local system.
Creation in the remote system takes place using a tRFC call of thefunction module BAPI_REL_MASSCREATERELATION. The function should bebefore the COMMIT WORK that starts the posting of the application inthe local system.

Notes
In the case of errors, an entry is written to the tRFC log. The tRFC isthen canceled, for example, if no RFC destination is found for thelogical system of the remote system.
To correct errors, you can add a tRFC-compatible destination for themethod CreateRelation of the class ObjectRelationService. You make thissetting with the transaction BD97 (in theImplementation Guide Basis Components --> Application Link Enabling(ALE) --> Sending and Receiving Systems --> Systems in Network -->Synchronous Processing --> Determine RFC Destinations for Method Calls
