So Item A Rev01 has a relation with Item B Rev 01 and Item C rev 01. In Teamcenter view property, I can see in the reference list, A rev is referencing both B and C.
When I do the attribute mapping, to map the referencing item ID with "relation":
"Item ID": ItemRevision.GRM(relation).Item_id /description="referencing item id"
only one of the two referencing item id is mapped. If more than two, there is no pattern for showing which one is mapped.
I have only done it on TCIC, have not try SWIM or NX.
Overall, for attribute mapping, is it only capable of mapping only single value property? will fail on property with multivalue?
