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

      Debi,

      Sorry, but I couldn’t possibly offer any better information than that which is contained in those links.

      Perhaps one of the other forum members will be more inclined to complete your chart for you… 

      Best Regards,

    In the above mentioned chart, probably I can help you add up the gATP module. gATP module is more at the execution side of the Planning data rather than planning the data itself ( which is done by other modules like DP, SNP and PP/DS ). So, the input to the gATP module would be the Planned data ( it could be Sales documents, STOs, POs, Stocks…). In short, the incoming demands look up to the reciept elements that were planned to fulfill the incoming demands. The output of the gATP module is the demand confirmation along with a schedule line ( a date on which the demand is fulfilled by APO ). The engine used here is ATP engine.

    Hope this helps.

    Thanks,

    Just trying to used your chart in order to complement it:

    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.

    DP is a Time Series-based planning Chart.

    Supply Network Planning

    Unconstrained Forecast from DP

    And from another source as BI or External systems (like Demantra)

    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)
