Following would be high level process-
- Define the key figure assignment and the product planning level for your promotions via
Advanced Planning and Optimization → Demand Planning → Planning → Promotion → Settings → Maintain Promotion Key Figures.
- Create a cannibalization group - Advanced Planning and Optimization → Demand Planning → Planning → Promotion → Settings → Maintain Cannibalization Group.
- In Interactive planning book - create and save an absolute promotion
