I want to filter data table based on lookup table selection as shown in below image.

Hi @adeelnazir786 ,

Sorry for that, We cannot understand your data model clearly, Could you please provide a mockup sample  based on fake data or describle the fields of each tables and the relations between tables simply? It will be helpful if you can show us the exact expected result based on the tables. Please upload your files to One Drive and share the link here.

Hi @adeelnazir786 ,

We can create a measure and use it in visual filter to meet your requirement:

VisualControl = 
VAR Title =
    SELECTEDVALUE ( 'data'[title], BLANK () )
RETURN
    IF (
        IF (
            ISFILTERED ( 'Sheet1'[key] ),
            CALCULATE (
                COUNTROWS ( 'Sheet1' ),
                FILTER ( 'Sheet1', CONTAINSSTRING ( Title, [key] ) )
            ) > 0,
            TRUE ()
        )
            && IF (
                ISFILTERED ( 'Sheet2'[key] ),
                CALCULATE (
                    COUNTROWS ( 'Sheet2' ),
                    FILTER ( 'Sheet2', CONTAINSSTRING ( Title, [key] ) )
                ) > 0,
                TRUE ()
            )
            && IF (
                ISFILTERED ( 'Sheet3'[key] ),
                CALCULATE (
                    COUNTROWS ( 'Sheet3' ),
                    FILTER ( 'Sheet3', CONTAINSSTRING ( Title, [key] ) )
                ) > 0,
                TRUE ()
            ),
        1,
        -1
    )

@v-lid-msft 

Great work! Please share dax to calculate the frequency (Existance count) of selected text (lookup text).

@v-lid-msft ,

I've been use part of your formula which returns the number of findings, that really working 😛 

CALCULATE (
                COUNTROWS ( Sheet1 ),
                FILTER ( Sheet1, CONTAINSSTRING ( Title, [key] ) )
            )

 Thanks & Regards,
