Default item category in Punchout Catalog for blank UNSPSC?

Summary:

Does "Default item category" work in Punchout Catalog for blank/empty UNSPSC?

Content (please ensure you mask any confidential information):

We are testing the default item category in our Punchout Catalogs. As far as we understand with this feature, the requester can now continue to submit a requisition even when a valid category mapping doesn't exist between the supplier and the internal definitions.

We have confirmed this worked. For example, we didn't have UNSPSC External Categories 31160000 map to an internal category, so the requisition errored out due to Blank Category Name. With the feature, the systems would know to default the Categories to "All items" even if we don't have the mapping.
