Hi Milind
In my opinion, the correct approach would be to use the ExternalIdentifier structure. This includes the ID of the service order in the source system, and also the ID of the source system itself.
ExternalIdentifier is missing from most APIs but it is starting to be introduced.
Hope it helps
