I’ve discovered an issue with the way Acumatica is managing the `POVendorInventory.IsDefault` field
We have a number of items that can be purchased in multiple UOMs which are set up on the VENDORS tab of the stock item. When removing we remove one UOM from the POVendorInventory table, the other purchase units are updated with the `POVendorInventory.IsDefault` field unchecked, leaving the item with no default vendor!
This error happens whether we manage the item from the stock item listing or the Vendor Inventory (PO201000) table.
The most confusing issue is that when you remove a UOM and save, the isDefault checkbox remains checked as True unless you refresh the page or hit Esc. This gives the appearance the the vendor remains the default vendor for the other listed Purchase Units
As I’ve noted elsewhere, this is a very odd field as it’s critical to a lot of purchasing and yet it is listed as “Nonexistent in DB” and can’t be updated via the Vendor Inventory (PO201000) screen or adjusted via Mass Actions on a GI
The question here is - How do we update a large list of items and remove a single Purchase Unit without removing the vendor as the default by accident??
