Filtering of VAR table by value in matrix

[tomislav]

Hi, 
I have created VAR table named JoinedTableX and in final part of calculation I need to filter its columns by values in matrix vizual (rows, columns).
And I don't know how to do that, so pls advise.

Sample table 

Duration Between Selected Folders TEST =
VAR MinCalDate =
    MIN ( 'Calendar'[Date] )
VAR MaxDate =
    MAX ( 'Calendar'[Date] )
VAR CaseIDX =
    VALUES ( Case_History_Summary[CaseID] )
VAR Folders =
    VALUES ( Case_History_Summary[Folder] )
VAR NextFolders =
    VALUES ( Case_History_Summary[NextFolder] )
VAR LastCaseHistoryIDForNextFolder =
    GROUPBY (
        FILTER (
            ALL ( Case_History_Summary ),
            MinCalDate <= Case_History_Summary[DatePST]
                && MaxDate >= Case_History_Summary[NextDatePST]
                && Case_History_Summary[CaseID]
                IN CaseIDX
                && Case_History_Summary[casehistoryid] <> Case_History_Summary[NextCaseHistoryID]
        ),
        Case_History_Summary[CaseID],
        Case_History_Summary[NextFolder],
        "Last casehistoryid", MAXX ( CURRENTGROUP (), [NextCaseHistoryID] ),
        "LastDate", MAXX ( CURRENTGROUP (), [NextDatePST] )
    )
VAR Table_FirstEntry =
    GROUPBY (
        FILTER (
            ALL ( Case_History_Summary ),
            MinCalDate <= Case_History_Summary[DatePST]
                && MaxDate >= Case_History_Summary[NextDatePST]
                && Case_History_Summary[CaseID]
                IN CaseIDX
                && Case_History_Summary[casehistoryid] <> Case_History_Summary[NextCaseHistoryID]
                && Case_History_Summary[NewToFolder] = 1
        ),
        Case_History_Summary[CaseID],
        Case_History_Summary[Folder],
        "First casehistoryid", MAXX ( CURRENTGROUP (), Case_History_Summary[casehistoryid] ),
        "FirstDate", MAXX ( CURRENTGROUP (), Case_History_Summary[DatePST] )
    )
VAR JoinedTable =
    FILTER (
        NATURALLEFTOUTERJOIN ( Table_FirstEntry, LastCaseHistoryIDForNextFolder ),
        [Last casehistoryid] > [First casehistoryid]
    )
VAR JoinedTableX =
    ADDCOLUMNS (
        JoinedTable,
        "DURATION", DATEDIFF ( [FirstDate], [LastDate], DAY ),
        "CaseIDXX", CALCULATE ( VALUES ( Case_History_Summary[CaseID] ) ),
        "FolderXX", CALCULATE ( VALUES ( Case_History_Summary[Folder] ) ),
        "NextFolderXX", CALCULATE ( VALUES ( Case_History_Summary[NextFolder] ) )
    )
RETURN
    SUMX (
        FILTER (
            JoinedTableX,
            //This part gives me problems
            [FolderXX]
                IN Folders
                && //Folders is selected value of Case_History_Summary[Folder] in matrix rows
            [NextFolderXX]
                IN NextFolders
                && //NextFolders is selected value of Case_History_Summary[NextFolder] in matrix columns
            [CaseIDXX]
                IN CaseIDX
        ),
        [DURATION]
    )

How it should look.

Your measure is computed for every single cell in the visual, including the values area and the Totals row and column, and for the Grand Total.  This will automatically filter by the matrix's row/column intersection. You can use SELECTEDVALUE() but that will mess with the totals.
