How to filter table with value related to the selectedvalue

[char23]

I have the two tables below in my power bi file. I have a slicer from Table2 that uses column [Month] as the selected value. If a month is selected, I want to calculate and filter Table1 where Table1 = the associated selected [Date Rank] from Table2 + 1. For example, if 24-Jun is selected from Table2, I want to filter Table1 where [Month] = 24-May.

Table1

ID	Status	Date Rank	Previous Status	Month	Type	Group
A	Normal	3	No previous	24-Mar	Task	<0
B	Normal	3	No previous	24-Mar	Task	1 to 5
C	Not Normal	3	No previous	24-Mar	Task	1 to 5
D	Not Normal	3	No Previous	24-Mar	Not Task	11 to 15
A	Not Normal	2	Normal	24-May	Task	6 to 10
B	Normal	2	Normal	24-May	Not Task	6 to 10
C	Normal	2	Not Normal	24-May	Not Task	6 to 10
D	Not Normal	2	Not Normal	24-May	Task	6 to 10
A	Not Normal	1	Not Normal	24-Jun	Task	1 to 5
B	Not Normal	1	Normal	24-Jun	Task	<0
D	Normal	1	Normal	24-Jun	Task	<0
E	Normal	1		24-Jun	Task	1 to 5

Table2

Date Rank	Month
3	24-Mar
2	24-May
1	24-Jun

Hi, @char23 

Thanks for lbendlin‘s reply. You can put this measure in filter pane and set to 1 to filter data.

filter =
VAR _month =
    SELECTEDVALUE ( 'Table 2'[Month] )
VAR _dateRank =
    CALCULATE (
        MAXX ( 'Table 2', 'Table 2'[Date Rank] ) + 1,
        FILTER ( 'Table', 'Table'[Month] = _month )
    )
VAR _result =
    IF ( SELECTEDVALUE ( 'Table'[Date Rank] ) = _dateRank, 1 )
RETURN
    _result

Thank you, I'm not sure if this would work for my visual since I have other measures on the same visual. Is there anyway to write this where the filter for 1 is in the measure itself? I am trying to understand how your formula works.

Hi, @char23 

The logic of this formula is to find the corresponding Date Rank of Table 2 according to the selected date and add 1. If the Date Rank of Table 1 is the same as the corresponding Date Rank of Table 2, then the Flag will be 1, otherwise, it will be 0. Add this Measure to the Filter box of the visual object, and set it to 1, then it will display all rows that have a filter of 1. What are the main problems you are currently facing that you can mark with a picture.

Add another column to Table2, call it "Next Date Rank", and set it to [Date]+1.  Use that column to join to Table1.

Thank you for the suggestion. Can you elaborate. I tried this method and still haveing trouble getting it to work. This is what I have below, but it just returns blank. 

VAR SelectedNextDateRank =

    CALCULATE(

        MAX('Table2'[Next Date Rank]),

        'Table2'[Month] = SELECTEDVALUE('Table2'[Month])

    )

RETURN

    COUNTROWS(

        CALCULATETABLE(

            'Table1',

            'Table1'[Date Rank] = SelectedNextDateRank

        )

    )
