Thank you for sharing! Your video and explanation helped me so much.

You sir just put an end to my 3h of searching for a video/article that will explain in detail how is this achieved! Thank you so so much!!

I am calculating the previous month sales and difference comparing with current and previous month but I get blank values in the column. How it is possible? This previousmonth function is not working for me.

do we need the dates from calendar table or can I get it from my fact tbale itself ? As, I have data till march but its comparing for April as well and summing it to 0 (for MOM comparison )

Hi, nice session. What happens when i drill up the MoM to see Data on X axis with Months or vice-versa

Hi Sir, Here if we select current year (2021) then it shows current month (Jan 2021) minus previous month (Dec 2022). but i want to show that if i select current year it will show same value for 1st month that is Jan 2021 without previous month value? can you tell us how to do it? if anyone here knows it they can help me thanks in advance

I just have one metric I want to do this for so example; I don't use 'quantity x price', but just 'quantity'. However, I did these steps for one metric (used SUM instead of SUMX ) which works to mimic the same values as the original 'quantity' values, however next step with 'last month' calculation does not work (no values are shown). Tips anyone?

How can you compare Month to Date (MTD) vs. Last Month to Date (LMTD) where the reflection and visualization of data shall be based on the current date TODAY(). Thanks.

Nice video, how can we restrict it use only single year, though I have selected a single year as 2021 in the slicer, but still Jan 2021 compares the values with Dec 2020. Is there a way to restrict only selected year ? Jan 2021 should be blank

Hello, I have a questions regaring Day on Day fuction - i understand why BLANKs showed up but is there any way that if we don't have a data from PreviousDay our measuer will take next No Blank value? Btw thanks for your videos that was a milestone for me :)

Great video, what about if I want to compare % change of 3 months interval. For instance % change between July and September
