eAM to iProcurement

I am also addressing this issue to Oracle support but wondered if anyone else has had this issue:

I have a problem ordering an Inventory Stocked part from a work order. Steps followed are: 1. Create work order in Maintenance Super User responsibility; From the operation execute the "Purchase Materials" button; 3. System punches out to iProcurement; 4. Search for item (stocked item with zero quantity on hand); 4. Enter quantity required, add to cart; 5. On Checkout requisition Information view, charge account is displayed (pulled from Organization set up) but Work Order and Operation are not. 6. Complete order process, requisition is created but of course, neither the item or the requisition appear on the work
