The Acquisitions module only allows a search of Vendors by Name, not ID number. We have 224 vendors with no names, but we can't search for them as there are too many in our system and it times out on a blank search. We can get the ID via a report, but we don't have a way to access the vendor account page to modify or delete it with only the ID number. Also, the vendor ID is populated in the item record. If you find that ID, then you would be able to search by it on items that does not have acquisition details linked to the item in the Holdings table.
