We are Presently doing Forecasting and Planning in an External system and bring the data into SAP and complete the Production execution and Order Fullfilment in SAP. We are planning to activate ATP in SAP and thinking of using GlobalATP in APO and leave the planning and forecasting in an external system.
I am an APO novice and would like to ask:
1. To perform ATP do we need all the issues(Sales Orders, Deliveries) and receipts(Purchase Requisitions, Planned Orders) in APO?
2. Once we download the Planned orders or Stock transport requests from external interface, do they get transferred to APO automatically? I guess CIF allows them to go automatically.
3. I guess in Apo the planned order and process order is a single elment. Is that Correct?
I appreciate your answers.
