We are setting up Vendor Management Inventory (VMI) with JNJ. If we give them a PO range, they can send us the PO using an 855 with Create and Acknowledgement. Is anyone doing this process and would you be willing to share how to set this up? I could not find the segment for Create and Acknowledge on the file layout for the 855. Do you use PO122 or import the PO with PO520?
