KPI Comparison based on previous data entry in dataset

It is best practice to use a Calandar table for all Power BI date logic

see https://www.youtube.com/watch?v=BtYn1hfdSAM

and https://www.youtube.com/watch?v=XjVLaVLluYE

and all the other Calandar training modules ... they are free !

Then your answer will be something like  ....

Distinct Count MTD = 
CALCULATE( 
DISTINCTCOUNT(Injury[(InjuryID]),
Calendar(MonthOffset) = 0)

Distinct Count previous month = 
CALCULATE( 
DISTINCTCOUNT(Injury[(InjuryID]),

Calendar(MonthOffset) = -1)

Distinct Count YTD = 
CALCULATE( 
DISTINCTCOUNT(Injury[(InjuryID]),
Calendar(YearOffset) = 0)

Distinct Count previous quarter = 
CALCULATE( 
DISTINCTCOUNT(Injury[(InjuryID]),
Calendar(QuarterOffset) = -1)

Thanks for reaching out for help.

I put in a lot of effort to help you, now please quickly help me by giving kudos.

Remeber we are unpaid volunteers and here to coach you with Power BI and DAX skills and techniques, not do the users job for them. So please click the thumbs up and accept as solution button. 

If you give someone a fish then you only give them one meal, but if you teach them how to fish then they can feed themselves and teach others for a lifetime.  I prefer to teach members on this forum techniques rather give full solutions and do their job. You can then adapt the technique for your solution, learn some DAX skills for next time and soon become a Power BI Super User like me. 

One question per ticket please. If you need to extend your request then please raise a new ticket.

You will get a quicker response and each volunteer solver will get the kudos they deserve. Thank you !
