I want measure the number of issues created in first 6 months and then in last 6 months of the year

Hi @irv45,

If you want to aggregate moths, then you should specify the Month level in the expression: [Time].[Month].DateMembersBetween.

And expression to group month from January till June for year 2024 might look like this:

Aggregate(
  [Time].[Month].DateMembersBetween('Jan 1 2024','Jun 30 2024')
)

Please see this post for a more dynamic solution:

Best,
