Hello Christopher
Control Parameter in the activity needs to be setup correctly.
Additionally please refer this old thread
Forecasting interactively and background in DP
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
