In a very simple EMT environment where you use EMT only to generate the initial purchase order and do everything else manually, you can just mail or fax the printed purchase order to the supplier. However, in a fully automated EMT environment, you use eCommerce Manager (35.22.13) to export the EMT purchase order from the PBU.

See Communicating EMT Documents with EDI.

If the sales order is on credit hold and Send Credit Held SO is Yes in Supplier Data Maintenance, the PO is sent to the SBU. If EMT Credit Flow is Yes in Customer Data Maintenance for the end customer, the resulting SBU sales order is placed on hold at the SBU.

See Credit Held Orders for more information.
