How do I do this? Variable table, limiting data based on selection

I can't get this measure to work... I'm half way maybe.  Here's my code:   O QTY OD FLOW = VAR bob = SELECTEDVALUE ( DateRanges[daterangeid] ) VAR origin = SELECTEDVALUE ( 'PrimaryMarketTa...

    Anonymous With regard to your question above you can store a variable and use it as a filter in another table like:

    Measure =
  VAR __table = SELECTCOLUMNS('Table',"FilterColumn",[Column])
  VAR __filteredTable = FILTER('Table2',[Some Column] IN __table)

Hi Anonymous ,

Bacause you do not provide a screenshot of the results you are expecting and desensitized example data, I could only according to your descriptions to give some suggestions, please try below dax formula, do some adjustments according to your measure:

O QTY OD FLOW =
VAR bob =
    SELECTEDVALUE ( DateRanges[daterangeid] )
VAR origin =
    SELECTEDVALUE ( 'PrimaryMarketTable ODflow'[PrimaryMarket] )
VAR test =
    CALCULATE (
        [O QTY L4wks removed origin city from dest OD flow],
        TOPN (
            5,
            ALLSELECTED ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
            [O QTY L4wks removed origin city from dest OD flow], DESC
        ),
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketdest] ),
        FILTER (
            ALL ( 'OD CitytoCityOrigin' ),
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] = origin
        )
    )
VAR jim =
    LOOKUPVALUE (
        'OD CitytoCityOrigin'[PrimaryMarketDest],
        'OD CitytoCityOrigin'[PrimaryMarketOrigin], origin,
        test
    )
VAR third =
    CALCULATETABLE (
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
        FILTER ( ALL ( 'OD CitytoCityOrigin' ), jim <> BLANK () )
    )
VAR secondtake =
    CALCULATE (
        [O QTY L4wks removed origin city from dest OD flow],
        TOPN (
            5,
            ALLSELECTED ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
            [O QTY L4wks removed origin city from dest OD flow], DESC
        ),
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketdest] ),
        FILTER (
            ALL ( 'OD CitytoCityOrigin' ),
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] IN third
        )
    )
RETURN
    secondtake

Thanks for your efforts & time in advance.

Thank you for your response, but I am still not there.  In your previous post you fixed my query (kind of) - the All ( 'OD CitytoCityOrigin' ) - this messes things up as it ends up grabbing the entire table.  I removed the All and it somewhat works.  

This is where I am at now - This one errors with "A function "PLACEHOLDER' has been used in a True/False expression that is used as a table filter expression."

OK - TEST1 gives me my top 10 cities that we sent trucks to.  I then need to combine that Test1 with those 10 destination cities now as the origin.  

Accroding to Dax Formatter - this query currently has a syntax error, but it isn't caught by power bi, so maybe not.  That syntax error is supposed to be here:

 

var DestCitiestable = 
    CALCULATEtable ('OD CitytoCityOrigin',
        [O QTY L4wks removed origin city from dest OD flow],  <--- HERE before the comma
     TOPN (
           10,
            ALLSELECTED ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
            [O QTY L4wks removed origin city from dest OD flow], DESC
        ),
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketdest] ),
        FILTER (
         'OD CitytoCityOrigin' ,
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] = origin && 'OD CitytoCityOrigin'[OriginQTY]>0   )
    )

 

 

Here is the full code, this does not work.

 

O QTY L4wks OD FLOW = 


VAR bob =
    SELECTEDVALUE ( DateRanges[daterangeid] )
VAR origin =
    SELECTEDVALUE ( 'PrimaryMarketTable ODflow'[PrimaryMarket] )

VAR test1 =
    CALCULATE (
        calculate([O QTY L4wks removed origin city from dest OD flow],FILTER (
            'OD CitytoCityOrigin' ,
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] = origin && 'OD CitytoCityOrigin'[OriginQTY]>0
        )),
        TOPN (
           10,
            ALLSELECTED ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
            [O QTY L4wks removed origin city from dest OD flow], DESC
        ),
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketdest] ),
        FILTER (
         'OD CitytoCityOrigin' ,
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] = origin && 'OD CitytoCityOrigin'[OriginQTY]>0   )
    )

var DestCitiestable = 
    CALCULATEtable ('OD CitytoCityOrigin',
        [O QTY L4wks removed origin city from dest OD flow],
        TOPN (
           10,
            ALLSELECTED ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
            [O QTY L4wks removed origin city from dest OD flow], DESC
        ),
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketdest] ),
        FILTER (
         'OD CitytoCityOrigin' ,
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] = origin && 'OD CitytoCityOrigin'[OriginQTY]>0   )
    )

var summarizeDestTable = 
ADDCOLUMNS(
    SUMMARIZE(DestCitiestable,'OD CitytoCityOrigin'[PrimaryMarketDest],"PrimaryMarketOrigin",'OD CitytoCityOrigin'[PrimaryMarketDest]),"aColumn",1)


VAR destcities =
    CALCULATE (
        calculate([O QTY L4wks removed origin city from dest OD flow],FILTER (
            'OD CitytoCityOrigin',
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] = DestCitiestable = origin && 'OD CitytoCityOrigin'[OriginQTY]>0
        )),
        TOPN (
           5,
            ALLSELECTED ( 'OD CitytoCityOrigin'[PrimaryMarketDest] ),
            [O QTY L4wks removed origin city from dest OD flow], DESC
        ),
        VALUES ( 'OD CitytoCityOrigin'[PrimaryMarketdest] ),
        FILTER (
         'OD CitytoCityOrigin' ,
            'OD CitytoCityOrigin'[PrimaryMarketOrigin] in summarizeDestTable && 'OD CitytoCityOrigin'[OriginQTY]>0   )
    )


RETURN
destcities

Again, I am not looking for you to fix my syntax, or make this query work - I am hoping you can help me understand how to do what I am trying to do in my two variables "SummarizeDestTable" and "Destcities" - here I am trying to limit my original Test1 query, isolate to the Destination cities (just top 10), and use those dynamically as my new Origin selection to pull another top 5 from those origins.

I would rather you give me the process, than repost my code with slight improvements.

Thanks,

Jonathan
