Hi Ramesh,

When you run the location Heuristic at DC level system create distribution demand on manufacturing plant. Purchase orders, planned orders and production orders are never created when run the heuristic at DC level. This distribution receipt in the supplying form of purchase requisition. At manufacturing plant in SNP, we usually carries out Planning run for generation of planned orders for inhouse production and purchase requisitions for external procurement. The SNP planning outputs are in the form of purchase requisitions and planned orders. After that we convert the planned order to production/process order in PPDS. After Deployment run, Transport Load Builder (TLB) is run to create shipment orders.

Please refer the SAP help link for more details.

I do understand that during external procurement Purchase requisitions are created in APO

I just want to know whether the created Purchase requisitions are converted to purchase orders or planned orders ..?

By the way  how to check the status of purchase order ..?

Can we convert purchase orders to purchase requisitions if there are any master data changes like planning delivery time ..?

Hi Ramesh,

Going to the basic purchase requisitions are converted to purchase orders only. It is not possible to convert Purchase requisitions to Planned order in APO or ECC.


By the way  how to check the status of purchase order ..?

APO is planning toll not the tracking tool. You can check them in ECC MD04.


Can we convert purchase orders to purchase requisitions if there are any master data changes like planning delivery time ..?

Purchase order is firm receipt it is not possible to reverse the purchase order to purchase requisition in standard SAP. You can short close the purchase order and create new with one with changed master data.

Hi Ramesh,

Purchase requisitions are converted to POs, this you can do in ECC or trigger from APO.

Status of purchase order can be tracked in ECC only, in APO you can see all planning relevant data for PO like source and destination locations, order quantity, start and delivery dates etc..

Purchase orders are not converted to PReqs as a part of standard SAP process, for automating the process you can enhance the system for your need.

Otherwise you have below options;

1) Go to transaction MASS ----> select object type "BUS2012 (Purchase orders)" ------> Execute and then select header or Item as per you need -------> click on fields ----> system will present you with fields from header or item as per you selection. Here you can also enter some specific PO document nos. or can change all in one go.

2) Or you can set the deletion flag on PO line item once there is a change in some master data, and create a new PO wrt. PReq.

Hello Ramesh,

There is already very solid inputs from other Experts of the group.

I would like to share my understanding about How Order Flows -

External Procurement Scenario:

Purchase Requisition -> Purchase Order -> Inbound Delivery -> Good Receipt -> Stock

In-house Production Scenario:

Planned Order -> Production/Process Order -> Confirmation -> Good Receipt -> Stock

And Sales Order Scenario:

Sales Order-> Delivery->Good Issue->Post Good Issue -> Order Completed.

Hope this will give you some additional insight.

Thank you
