Purchasing:Purchasing-Ordering specific items from Pfizer/Hospira

Procedures (specific) for ordering from Pfizer (legacy Hospira items)

Recently Pfizer (#22337) acquired the marketing rights to a number of products that we used to purchase from Hospira.
Pfizer has specific criteria for ordering these items (related to unit of measure UofM) that are unique to how our normal item/ordering processes work.
More details - When we create an item it has to be built based on established "rules" concerning UofM, UPC, size fields, pricing etc. that are critical for purchasing/receiving/put-away/picking processes. Pfizer has asked us to order a product that we sell as an each (EA) with a UPC printed on the selling box and is packed as 25 eaches in a pack (PK) - as an EA on the PO (but as a pack of 25). Example below;

To comply with Pfizer's requirements the following solution has been developed. Pfizer has told us that they will be able to process our PO's will only the vendor item # (no UPC).
We have created another item # that will be used/switched by the purchasing department before sending PO's to Pfizer (more details below).
Set up of secondary item (real item in our system, but only for PO ordering purposes).
