Hi experts,

I am new to APO world and I just want to know few basic concepts about it - the input and output of each module in APO.

Module InputOutputEngineEffect in ECC / OLTP System (Through CIFing)
Demand PlanningSales Order History Data from OLTP SystemUnconstrained Forecast or DemandForecast Models (e.g. Univariate/Seasonal)No effect - No orders etc. are created.
Supply Network PlanningUnconstrained Forecast from DPPR, STR & SNP Planned OrdersHeuristic/Optimizer/CTMPR, STR, Planned Orders
SNP Deployment RunATD Receipts & ATP IssuesChange the ATP Category of STROptimizer / HeuristicSTR (No change)

Please correct me if I have written anything wrong in the above table.

What i need is :-

What is the "input / output / engines / effect in OLTP system" of other modules like :- PPDS, TLB, GATP.

Please suggest. I guess, this will help to clarify the doubt of many APO freshers.
