Measure to rank within subcategories (for filtering table visual to TopX within subcategory)

[morrtenjansen]

Context: TransactionTable "RepdataH". It has dimTables on it, but that will be in a next step, current issue only concerns RepdataH.

I need to rank the records via a measure, as it is, within a category ("Restaurant"), and I have a number to rank by ("Random number ..."), per record. That is to show a table with a random subset (say, 3) of records per restaurant.

But when used in a table (only using fields from RepdataH) all records get rank 1.

(Most of the tips I have found regarding "Rank by Category" or "Get topX by Category" use calculated columns, but I need it interactively,)

Pls. advice (all the VARing is mostly for testing purposes).

MsrDraw =

VAR er = MAX(RepdataH[Restaurant])

VAR tbl =

SELECTCOLUMNS(

    Filter(

            ALL(RepdataH)

        ,

            RepdataH[Restaurant]=er

    )

,

        [Random Number …]

)

VAR en = MAX(RepdataH[Random Number …])

VAR rx =

rankx(

    tbl

,

    en

)

RETURN

rx

Thanks for advise.
