Basic APO Functionality
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.
The answers to your questions can be found by searching SAP documentation, or by taking basic classes.
Here is a site that has some nice high level documentation for you to look at:
PPDS online help
TLB online help
GATP online help
Good Luck & Best Regards,
Thanks for the update.
Request you to give some high level information in this regards.
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...
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.
Just trying to used your chart in order to complement it:
No effect - No orders etc. are created.
DP is a Time Series-based planning Chart.
Unconstrained Forecast from DP
And from another source as BI or External systems (like Demantra)
ATD Receipts & ATP Issues
