Hi, how are you? Thank you very much for the reply.
Do I annoy you if I ask you to clarify me a little more? I'm new to power bi
The idea is to see the difference of "goal fulfillment" if it improves or deteriorates, with respect to the previous staff_week, of each evs id (these are repeated week by week)
As I said, I do not do it with dateadd because the date does not exist, it is actually that only "staff_week"
From already thank you very much!
