Need help on the DAX formulation

Question

I would like to prepare a PBI report with below parameter.

Net New – Any user who used the Application in the last month and hasn't ever used before.
Any user who used Application in the last month (e.g., Sep 2022), but didn’t use it for over 6 months before Last month (e.g., didn’t use in the timeframe of Aug –Mar 2022).

Any body can help on how to prepare the DAX formula for above condition.

Hi,
I usually try to solve this types of problem by using INTERSECT and EXCEPT DAX functions.
If possible, please share your sample pbix file's link here, and then I can try to look into it to come up with a proposal.
Thanks.

Hi&nbsp;lavadba
&nbsp;
Based on your description, I have created a simple sample:

Please try:
First create three measures:
&nbsp;
Count Last Month = COUNTX(FILTER('Table',MONTH([Date])=MONTH(TODAY())-1),[User])

Count Before = COUNTX(FILTER('Table',MONTH([Date])&lt;MONTH(TODAY())-1),[User])

Count 6 Month Before Last Month = COUNTX(FILTER('Table',MONTH([Date])&lt;MONTH(TODAY())-1&amp;&amp;MONTH([Date])&gt;MONTH(TODAY())-8),[User])

&nbsp;
&nbsp;
Then create a new table with [User] Column and rename it:

&nbsp;
Apply the measures to the visual level filter:

Recreate a new table for users who&nbsp;didn’t use it for over 6 months before Last month and apply filter:
&nbsp;

Final output:

Hi&nbsp;lavadba&nbsp;,
&nbsp;
I can't get enough details from your&nbsp;screen shot. Could you please provide more details about your data? Such as another month and your source table.
Please provide me with more details about your table and your problem or share me with your pbix file after&nbsp;removing sensitive data.
