Statistical Forecast Models Using Forecast Assignment Table

[former_member717176]

Hello all.  I need some help.

I am trying to setup a background process to execute Statistical Forecasts in background using the models stored in the table /SAPAPO/DP_FCST2

Can anybody offer advice with regards the best approach.

Is there a specific Forecast Strategy or User Exit that should be used?

Thanks

Hello Christopher

Control Parameter in the activity needs to be setup correctly.

Additionally please refer this old thread

Just want to add some additional information on this topic  -

In Planning Book, Goto Settings => Forecast Profile => Assignments: There are three options available -   

1) Save assignment of selection for forecast profile - This allows users to save changes to original forecast profile

2) Save assignment with unique forecast profile - (this allows for the planner to fine tune a model but then save it to a unique GUID instead of over-writing the original profile itself.  Typically, DP Planner are expected to use this option.

3) Do not save assignment and forecast profiles  - This also allows users to over-write the original forecast profile settings without saving the assignment

Additionally if this /SAPAPO/FCST_GUIDS parameter is set to “X” then it will result into system saving any forecast profile changes as a unique forecast profile(GUID based).

Also when generating the forecasting (using option#2 above )interactively, it is important to use same planning levels(selection id) as defined in aggregation levels in background job.

Hope this will help.

Thank you

Hi Christopher,

First you need to go to transaction /SAPAPO/MSDP_FCST2 - Environment -> Assign Forecast Profiles to a Selection and make sure that the profiles are assigned to the desired selection.

Then, you have to define a Forecast Activity using transaction /SAPAPO/MC8T - Define Activities for Mass Processing and make sure you uncheck the control parameter Always Use Forecast Profile

Indicator: Always Use Forecast Profile of the Job

If you wish this forecast profile to be used always with this selection when the forecast is run, check this box.  You specify the selection in the mass processing job. Otherwise, the system uses the forecast profiles that have already been assigned to any selection contained in the mass processing job. You can  display and change these assignments in the Assign Forecast Profiles transaction (Demand Planning -> Environment -> Assign a Forecast Profile to a Selection).

Finally, you set up a background job where you call your forecast activity , execute then voila.

Let me know if you need any additional details or if you have questions,

Regards,
