Level 2 Sprint 3 INV01 - Not 1st week of Timescale?
I used the "NOT INPERIOD(CURRENTPERIODSTART())" formula to calculate to determine if it's the first week of the time scale or not and it's working. But i know that if we change the current period my formula doesn't not work anymore. I couldn't find a formula that targets the start of time scale and not the current period. Could you help me ? @einas.ibrahim
