Let's say I have below table. I'm wondering if there is a way in Power Query to fix this planning.

The order of processes should be first by priority, and then by date.
As you can see, there is a problem on 11-1-2021 to 15-1-2021, where the resource usage is 175%.
I would like to move al processes forward in time that are conflicting, while respecting the desired order of the processes. Obviously processes of 25% and 75% could run on the same day.

Below things come to my mind that could be part of the solution, but I don't know how to make cake of it.
  • Group by Date and sum Resource usage shows me the conflicts.
  • Merging with a date table and calculating resource availability for each day.
  • Using a recursive function?
  • Using a loop?
I know it's perhaps more straightforward to do this with VBA, but I would really like to learn if something like this is possible in PQ.
