Hi Stephenie,
Just wanted add one more pointer -
Following five fields are the key fields(primary key) for Table name : /SAPAPO/DP_FCST2.
Client
Name of DP Planning Area
Selection ID
Key Figure (many time key figure field is a culprit for this behavior - its a good idea to leave this field as blank)
Name of Planning Version
By looking at the current design in your system if you ensure these above five fields has or gets the SAME value - either when running forecasting interactively or when running it through FC Optimization. If you able to achieve this, then you will end with only single entry in //DP_FCST2 table. Hence there will not be more than one forecast assignments for the single/same selection.
As mentioned above, Please watch out for value in Keyfigure field in this table - Forecast Profile assignment done by Interactive Planning leaves this field value as BLANK, please check what happens with entry created by Forecast Optimization.
Since I do not have ABC_XYZ configured in our system, I am not able to visualize further.
Hope this will help you get some clue.
Thank you
