Measure not counting correctly when filtered

[SeanB004]

Hi all, I have a DAX query. I have table that filters the number of Sales Opportunities on a weekly basis from a specific deal source. However when doing a weekly difference calculation, I find the Previous week measure to be calculating all the opportunities in the previous week and not particularly filtering the ones for the specific deal source.

you can see the previous week numbers below dont correlate. I've also attached the formula I used. Help appreciated 🙂

Hi @SeanB004 ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data. 

(2) We can create a measure. 

previous = CALCULATE([Number of Oppts],FILTER(ALL('Table'),'Table'[Deal Source]=SELECTEDVALUE('Table'[Deal Source]) && 'Table'[Weeknum]=SELECTEDVALUE('Table'[Weeknum])-1))

(3) Then the result is as follows.

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

Best Regards,
