For purchase requisition items that were not assigned to sources at the time of their creation, you can perform either of the following actions:
Collectively assign sources and convert these purchase requisitions using a single transaction.
First, assign the purchase requisitions to sources, and then continue processing the assigned items with other transactions.
If you want to carry out the assign and process steps together, use the Assign and Process function for purchase requisitions. This function is a combination of the Assign Source to Purch. Requisition function and the Ordering: Assigned Purchase Requisitions function.
You can trigger the automatic assignment of sources for all selected purchase requisition items from a list of open purchase requisitions. If there are several sources of supply for a material, you can choose the desired one from a list of all possible sources.
You can manually assign requisitions for which no source was found to a vendor. You can also flag them for RFQ processing (Edit → Flag for RFQ → Without Vendor/With Vendor). You cannot save the flag for RFQ. Convert the purchase requisitions that are marked for a request for quotation into RFQs immediately; otherwise, the assignment will be lost when you leave the transaction.
After the system makes the assignment, you can save your purchase requisitions with the assigned source or convert the items now assigned into purchase orders, scheduling agreement delivery schedule lines, or RFQs from within the assignment overview. If you select the requisitions that have already been assigned, and the automatic source determination process identifies a different source than the one already determined, the previous source is overwritten without prior warning.
On the SAP Easy Access screen, choose Logistics → Materials Management → Purchasing → Purchase Requisition → Follow-On Functions → Assign (ME56) to assign purchase requisitions.
On the SAP Easy Access screen, choose Logistics → Materials Management → Purchasing → Purchase Requisition → Follow-On Functions → Assign and Process (ME57) to assign and process purchase requisitions.
Both transactions are also available as an app. The apps are as follows:
- Assign Source of Supply to Purchase Requisitions (ME56)
- Assign and Process Purchase Requisitions (ME57)
On the SAP Fiori launchpad, the Process Purchase Requisitions SAP Fiori app is also provided. The differences to the SAP GUI transactions are as follows:
- Mass selection and assignment is not possible. You have to assign the sources one by one.
- Automatic assignment is not supported. Quota arrangements and source lists are not considered.
After the manual assignment you can convert the requisitions to purchase orders, contracts, and RFQs. Multiple selection is possible for the generation of the follow-on documents.
