Basic APO Functionality

[Former Member]

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	Input	Output	Engine	Effect in ECC / OLTP System (Through CIFing)
Demand Planning	Sales Order History Data from OLTP System	Unconstrained Forecast or Demand	Forecast Models (e.g. Univariate/Seasonal)	No effect - No orders etc. are created.
Supply Network Planning	Unconstrained Forecast from DP	PR, STR & SNP Planned Orders	Heuristic/Optimizer/CTM	PR, STR, Planned Orders
SNP Deployment Run	ATD Receipts & ATP Issues	Change the ATP Category of STR	Optimizer / Heuristic	STR (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.

Thanks,

Debi
