Hello is there a way to fill the gap with running sum function when there are null values in some alternative weeks, prior to the last week with values point?
For instance if week 4 is null but week 5 and week 3 had a value. the running sum doesn't show anything in those cases.
I have tried something like this,
However, i don't make it to stop in the last point which also fulfills the condition of being null.
