Hello Kevin,
When I saw 'Promotion Planning Error.JPG' (which you had uploaded while posting your initial question) it shows Promotion being created with name PROMO T-FV100 V1. I tried to explain this in Point#1 in my previous response to you.
Yes Objects can be assigned only after you create the promotion. You will see button in MP34 screen.
As per my understanding, sequence of steps would be
1. Maintain Promotion Key Figures using MP33. Whatever Characteristics and Key figure you maintain in MP33 gets visible in MP34 screen as well.
2. Create Promotion using MP34. This is screen which looks very similar to Interactive Planning Book. On top left corner (above selection profile icon), you have small white color icon which is used for creating promotion.
3. Assign Objects (Specify Levels and Characteristic for the promotion)
4. Activate the promotion
Besides above steps, you have a few optional features/settings which can be used in Promotion Planning.
- MP40 can be used to create promotion base (refer my previous response for its usage). I think you have used that feature while creating your promotion(based on uploaded screenshot).
- MP31 can be used to defined attributes, which helps in additional selection criteria or navigation in MP34.
- If you foresee cannibalization effect due to promotion, then you can define the same using by using cannibalization profile MP32
Frankly, I am kind of short of input/ideas now, also I am not an expert in Promotion Planning area. I will say, Good Luck to you and hope you will be able to put all this together to make Promotion planning works.
Also May I request you revert with your learning's once you fix the current issue to benefit the community.
Thank you
