Need to get only Item specific UOM while creating BPA and Standalone Purchase Order.

Summary:

While creating BPA and standalone Purchase order, we need to get item specific UOM. Currently application populates all UOM that are in place.

Content (required):

While adding an item at line level in Purchase order and BPA, UOM LOV populates all UOM that are defined in the application. But we need to restrict UOM LOV that are item specific. We are looking for any kind of possible way to sort this out.
