Calculating Previous Week Data

[clarkey1988]

Hi,

I wonder if anyone cna help me. I'm trying to calculate the previous week's sum of weight. So for week 20 in the screen shot below I need the Previous Week Weight column to reflect Week 19's weight (542,843). Currently my measure is showing 540,827. I have 5 filters shown in the screen shot and have included them in my measure but I seem to be pulling correctly on some but not others.

Any help would be greatly appreciated!

Hi, @clarkey1988 

According to the sample picture you posted, the measure seems to be correct and useful. And it seems that the reason why the value of the 20 Week is blank is that the [week number] has been filtered by the visual filter?

You can try to remove the filter and check if the measure can work.

If you still have a problem, you can post some sample data(without sensitive data) and your expected result.

Hi @v-robertq-msft 

That filter was jsut the top 2 max weeks so don't think that has an impact. However, I had 4 filters in my original picture. Once I clear them the measure works correctly. Somehow the filters are breaking the measure - but I thought I accounted for them in the measure code itself?

Hi, @clarkey1988 

If you think that the filters are breaking the measure, I suggest you to use the ALL() function to replace the ALLExcept() function in your original measure. Because the ALL() function can ignore any filters outside that might have been applied to avoid the effect of the visual filter.

ALL() function in DAX

Hi @clarkey1988 

Would you able to share the pbix file?
Also, I think the week - 1 logic should not be included under ALLEXCEPT.

Hi @clarkey1988 

Try it without MAX in your formula at the end. So, keep it like 'Degama'[Week Number] = 'Degama'[Week Number] - 1

Hi @dkaushik - unfortunately that did not seem to work. It actually didn't pull any values using that logic in the measure.
