Return Max Date based on column filter

[Anonymous]

I'm in need of some dax help. I have a table that contains 2 columns; Date & Event. I only want to see the date that is associated with a specific event. For example in the table below I only want to see the dates with the event that begin with "FM". 

Date	Event
7/12/2021	FM Party
1/5/2020	Corporate Event
5/6/2021	FM Event
1/1/2022	Event FM
2/5/2020	Business FM
6/6/2021	FM Meeting

Thank you for any assistance

Hi @Anonymous 

You can create a measure with the logic such as the following:

Measure = CALCULATE ( MAX ( TableTest[Column1] ) , LEFT ( TableTest[Column1] , 2 ) = "FM" )

 Adjust Column1 to 'TableName'[Event] and should be all good from there.

Hope this helps!

Thank you Theo - one more caviot, I need the other events to appear in the report as well, but they will show a blank value.

Thanks again for your help

Hi @Anonymous 

If you can mark the first one as a solution just so that others can use it given your original post, that will allow better solution identification down the track. However, to get you the additional caveat item, you can use below:

Measure = 

VAR _1 = CALCULATE ( MAX ( TableTest[Column1] ) , LEFT ( TableTest[Column1] , 2 ) = "FM" )
RETURN
IF ( LEFT ( TableTest[Column1] , 2 ) <> "FM" , BLANK() , _1 )

 Hope this helps!
