I’m trying to view the details of a PO that’s linked to a SO line. My API call, {{api_base_uri}}/SalesOrder/SO|SO00000051?$expand=Details, works just fine. However, when I try {{api_base_uri}}/SalesOrder/SO|SO00000051?$expand=Details,Details/PurchasingDetails, I get an error stating “the given key was not present in the dictionary”.
I may have been misinformed on this being the correct key, but there’s nothing online covering this topic.
Can I please get some help?
Context: I’m trying to create a collection run in Postman that creates an SO + PO, then PO links their lines. I’m on 2023 R1.
