## How to calculate next 4 weeks demands (not standard calendar, but the combo of week such as 2022001)

Hey all,

I try to calculate next 4 weeks demands. But it doesn't depend on the standardized calendar but on the combo of year and week, such as 2022001 1st week of year 2022). For example, in week 1 2022, (2022001), my next 4 weeks demands should cover from 2022002 thru 2022005.

I initially set up as below, but that doesn't work for me. Any thoughts? Thanks!

If you only use "[YearAnd Week]<=CurrentYearAndWeek+4" then the formula will consider all weeks before CurrentYearAndWeek+4 which is more than 4 weeks, to make it correct and keep it in the exact period you need to cap the lowest amount and highest amount.

In your dax formula, in the filter try to write something like below:

Filter(all(table),[YearAnd Week]>=CurrentYearAndWeek&&[YearAnd Week]<=CurrentYearAndWeek+4)

rather that SELECTEDVVALUE you can use MAX.

Hey Vahid,

Thanks for your help. I still see there is off for some calculation. But I think your logic is right. Would you mind explaining the login for below dax.  Is that ok for me to only put "[YearAnd Week]<=CurrentYearAndWeek+4" In other words, why should we put "[YearAnd Week]>=CurrentYearAndWeek"?  Thanks!

Filter(all(table),[YearAnd Week]>=CurrentYearAndWeek&&[YearAnd Week]<=CurrentYearAndWeek+4)
