Confirm Shipment accounting for PO ordering unit of measure

Idea Summary:

Currently, Confirm Shipment is failing when the ASN is sent by the supplier in the PO ordering UOM and the API is not doing the conversion from the item ordering unit of measure to the item inventory unit of measure. The idea is to have Sterling OMS automatically do the conversion from the item ordering UOM on the ASN to the inventory UOM and confirm the shipment accordingly.   

Business Rationale:

When a PO is sent to the supplier, the ordering unit of measure may be different than the inventory unit of measure. For example, the supplier may only sell a product by the CASE or by the REEL, while we store it and sell it to our customers by EACH or by FEET. Therefore, when we create the PO, we use the ordering unit of measure of the supplier. When the supplier ships the item, they will in turn use the ordering unit of measure that the order came in. Therefore, the ASN sent by the supplier and used to confirm the shipment will be in the ordering UOM. 

Sterling does the conversion correctly on the PO create side and we can see that the inventory supply for the item for the Supply Type of "Purchase Order Created" is correctly converted from ordering UOM to the inventory UOM. On the other hand, Sterling fails and does not automatically do the same conversion on the shipment confirmation side when we receive the ASN from the supplier. 

This issue was raised with IBM Support (related case# provided) and they indicated that the product only takes the inventory UOM to create/confirm shipment. While this is not an issue for Sales Orders, because we are shipping the item and we know our own inventory UOM, for POs it is an issue because the supplier sending the shipment confirmation ASN does not know our inventory UOM. 

The information needed for the conversion from an item ordering UOM to the item inventory UOM and implement this idea is readily available in Sterling OMS Item Master.
