Infor LN & Baan Tip: What conditions must exist before changing an item's inventory unit?
Is there a procedure for changing an item’s inventory unit? What conditions must exist before it can be done?
Once inventory transactions (receipts or issues) have occurred for an item, the inventory unit cannot be changed. If only orders have been placed against the item (sales or purchase), the inventory unit can be changed if these orders are removed and the economic stock of the item is zero.
The reason that the inventory unit cannot be changed once transactions have been made is due to how transactions are recorded. The inventory transactions are recorded in units. These units are the inventory unit of the item. The inventory unit is not held in this table, however. The inventory unit is held on the item data. For example, if 5 pieces (pcs) of an item are issued and the inventory unit is later changed to pounds (lbs), there will be a mismatch in the inventory history of the item. In the past, the item was issued as pcs, and now the item master inventory unit is lbs. As the inventory unit is not date effective, the inventory has then been issued in two different units (pcs and lbs), but there is no method to recognize this difference.
