I am trying to show 7 days before sales quantity on column.
For represent task clearly, let me show result table as a screen of excel, which I am looking for, but in aiming of simplicity, not for 7 days before, but 1.
Sorry of using not a power bi data scree. That's cause of big data volumes in power bi area
Tryed to use LOOKUPVALUE and DATEADD, but without success
