Filtering on Date complex

Hey,

basically what you are looking for is called the "Event in Progress".

Please be aware, that solutions for these kind of questions require that the Calendar table is not related to the fact table. 

Here you will find a pbix file that contains a little example, based on your sample data it shows 3 rows valie for the selected month "2016-06":

I've created a measure "Active WorkID"

Active WorkID = 
SUMX(
    'Fact'
    ,
    var theEnd = IF(ISBLANK('Fact'[EndDate]), DATE(9999,12,31), 'Fact'[EndDate])
    return
    IF(AND('Fact'[StartDate] < [Min Selected Date], theEnd > [Max Selected Date])
        ,1
        ,BLANK()
    )
)

that I'm using with the card visual. this measure returns the value 1 one for each WorkID that is "active". This measure can also be used in the Visual level filter section of a visual.

Hope this is what you are looking for

Regards

Tom

Hey,

so you are saying 

Month('startdate' + 45) = Month(Selected)

Left side

2014-07-01 + 45days = 2014-08-15 --> Month = 8

Right side

2018-08 (Selected Month) = Month(...) = 8

this comparison equals to true?

Not sure what you mean if you are saying you can't see trends, trends of what

I would consider this a trend.

I have to admit that I have my difficulties to understand your requirements, sorry for that

Regards

Tom
