Hello, I have a question:
the first measurement is to remove products from lower 5 € category, which makes up 15% of sales volume in year 3. After removing this 15%, we donnot know, how this 15% were compensated by products from the other 4 categories ( the exact percentage change is unknown).
In the calculation of the gross profit margin planning, it is calculated based on the percentage distribution from year 3. However, to get 100% in total, don't we need the exact changed percentage of the rest 4 categories at first, then calculate the gross profit margin?
We removed the category lower 5€. So the situation changed. I do not understand the logic of the gross profit margin calculation based on data from year 3. 15%+10%+30%+40%=85%, not 100%. This is a problem.
