Dynamic value lookup

Hi, Anonymous 

Based on your decription, I created data to reproduce your scenario. The pbix file is attached in the end.

Keyword:

Calendar(a calculated table):

Calendar = CALENDARAUTO()

There is no relationship between two tables. You may create a measure as below.

Visual Control = 
var _date = SELECTEDVALUE(Keytword[Date])
var _keyword = SELECTEDVALUE(Keytword[Keyword])
return
IF(
    _date in DISTINCT('Calendar'[Date])&&
    COUNTROWS(
        FILTER(
            ALL(Keytword),
            NOT(Keytword[Date] in DISTINCT('Calendar'[Date]))&&
            Keytword[Keyword] = _keyword
        )
    )=0,
    1,0
)

Finally you need to put the measure in the visual level filter and use the 'Date' column from 'Calendar' table to filter the result.

Best Regards

Allan
