Purchase Order Creation from a Sales Order in SAP CRM

Use

After a sales order, or sales order item, has been created and the planned purchase order (PO) or PO item has been released in SAP APO, then SAP CRM triggers the creation of the purchase order in the ERP system ( Materials Management – Purchasing, MM-PUR). If this purchase order has a reference to a purchase contract that has been made with a vendor/supplier, the ERP system updates the call-off history of this contract. When this PO is saved, the following happens:

SAP ECC returns the updated information to SAP CRM, where the document flow between sales order and PO is updated accordingly, both on header and on line item level.
SAP ECC forwards the purchase order to SAP ICH.
SAP ECC (MM-PUR) generates a message that causes the PO to be sent to the vendor.

It can be generated as an e-mail, fax, electronic data interchange (EDI), and so on; it can be sent immediately or at a later date.

The following figure illustrates the process flow and system communication:
