I am trying to attach a preferred vendor to an item. My request is successful but the Vendor doesnt show up. The audit log is interesting; it is saying that I unset the vendor in the same request. Any tips?

<ns31:itemVendorList>

<ns31:itemVendor>

<ns31:vendor internalId="25030"/>

<ns31:purchasePrice>46</ns31:purchasePrice>

<ns31:preferredVendor>true</ns31:preferredVendor>

</ns31:itemVendor>

</ns31:itemVendorList>

I just tried it using the same XML you have there and it worked for me. Since the system notes show that it’s being set and then unset, I would look for

afterSubmit

scripts/workflows that may be working here. Start with Customization > Scripts > Scripted Records and see what’s running in

afterSubmit

.
