Hello team, As far as my understanding, externalId in OrderHeader is used to save orderId reference of any other system into our system.
If this is the only case, we should also maintain something similar on following entities as well as consistency and they will be in need in case of a full-fledged integration with OFBiz environment with any other system: 1. ReturnHeader 2. ContactMech 3. Party (already exist) 4. Facility 5. Product (can be discussed, Identification type SKU can also do the job) Please let me know your thoughts on this. -- Best Regards, Suraj Khurana Technical Consultant
