Importing the EMT PO into the SBU
The SBU uses eCommerce Manager to import the created EMT PO. When it has created a confirmed secondary sales order from the PBU’s purchase order, the SBU sends an acknowledgment to the PBU. The PBU imports the PO acknowledgment and the system changes and registers the transmission status.
The PBU cannot modify the primary sales order until it receives an acknowledgment from the SBU unless Require Acknowledgments is set to No in Purchasing Control (5.24) at the PBU.
