Converting Individual Orders In Interactive Planning 
Use
You can directly trigger the conversion of planned orders into production orders and purchase requisitions into purchase orders on the interactive planning screens of the
Product View and the Product Planning Table. The orders you designate for conversion in the APO System are sent to the connected OLTP System and are automatically converted there.
Procedure
Product View or the Product Planning Table from the SAP Easy Access Menu by choosing Production Planning ® Interactive Production Planning
® Product View or Product Planning Table.
The Product View or the Product Planning Table screen appears.

For a purchase requisition to be automatically converted into a purchase order, a procurement alternative must be assigned to the requisition.
The system sets the conversion indicator for the selected orders.
The orders designated for conversion are transferred to the connected OLTP System, where the conversion is triggered automatically.

If you create an external procurement order and immediately set the conversion indicator for this order, the OLTP System automatically creates a purchase order once you have saved the data. No purchase requisition then exists for this order in the OLTP system.
If you wish to create a purchase order with reference to a requisition, you must first save the external procurement order and wait until the requisition data has been passed on from the OLTP system to the APO system. When this has taken place, you can set the conversion indicator.

Subcontracting requisitions and purchase requisitions relating to OLTP scheduling agreements cannot be automatically converted in the OLTP system.
To convert these requisitions into purchase orders or scheduling agreement delivery schedule lines, use the Create Purchase Order via Assignment List function in the OLTP system.
