Double Filter on the Same Facts

Hello I have a 'dim-selection ' table, like

 

SelKey, Dilm1-Field1, Dim1-Field2,Dim2-Field1,Dim2-Field3

 

The file is created from other dimensions and has 1 key, that key goed back to the Facts.

 

The goadl would be that on the left off the csreen the used choses one set of selections and sees the results in a visual. On the right a second selection also to a visual.

This works fine when using 'Edit Interactions'

But now, the user would like to have a chart with both values compared ...

 

As the Facts holds over 500miljon rows, and there are over 90 measures defined I would like to find a structural solution instead of doubling all measures and use a USERELATIONSHIP on the doubled versions ...

 

Any idea if this would be possible ?

    With edit interactions you can play with selections going into one visual and other selections going into another viual, but you can't combine them afterwards (or I havn't found hwo to).

    So I went back to the database. My selections are based on 5 fiels, coming from 3 tables.

    So first I created a selections table like this

      CREATE TABLE [edw_aps_goalpubdb].[ENGINE_SELECTIONS_New]
             WITH ( DISTRIBUTION = HASH([ID_PLANNING]),
                    CLUSTERED COLUMNSTORE INDEX )
      AS
    
      SELECT ROW_NUMBER() OVER (ORDER BY [ID_PLANNING]) AS ESEL_UID
           , [ID_PLANNING]
           , [DESCRIPTION]
           , [CONTEXT]
           , [PERIOD_CODE]
    	     , [MATERIAL_GROUP_CODE]
    	     , [DW_DAY_START]
           , BINARY_CHECKSUM([ID_PLANNING],[CONTEXT],[PERIOD_CODE],[MATERIAL_GROUP_CODE],[DW_DAY_START]) AS ESEL_CHECKSUM
        FROM (SELECT DISTINCT
                     P.[ID_PLANNING]
                   , P.[DESCRIPTION]
                   , P.[CONTEXT]
                   , P.[PERIOD_CODE]
    	             , EM.[MATERIAL_GROUP_CODE]
    	             , DATEPART(DW,ES.[DAY_START]) AS DW_DAY_START
    	          FROM [edw_aps_goalpubdb].[PLANNINGS] P
    	               INNER JOIN [edw_aps_goalpubdb].[ENGINE_MATERIAL] EM ON EM.ID_PLANNING = P.ID_PLANNING
                     INNER JOIN [ods_aps_goalpubdb].[ENGINE_SOLUTION] ES ON  ES.ID_PLANNING = EM.ID_PLANNING
                                                                         AND ES.ENGINE_CODE = EM.ENGINE_CODE
             ) X1
      ;

    The Facts have one link to this table based on ESEL_UID (Facts are coming from ENGINE_SOLUTION).

     

    Then I created a Cross-Table for all possible selections.

      SELECT ROW_NUMBER() OVER (ORDER BY ESEL_UID, ESEL_VERSION) AS ESEL_2_UID
           , ESEL_VERSION
           , ESEL_UID
           , ID_PLANNING
           , DESCRIPTION
           , CONTEXT
           , PERIOD_CODE
    	     , MATERIAL_GROUP_CODE
    	     , DW_DAY_START
           , ID_PLANNING_2
           , DESCRIPTION_2
           , CONTEXT_2
           , PERIOD_CODE_2
    	     , MATERIAL_GROUP_CODE_2
    	     , DW_DAY_START_2
        FROM (SELECT CAST (1 AS SMALLINT)         AS ESEL_VERSION
                   , ESEL1.[ESEL_UID]             AS ESEL_UID
                   , ESEL1.[ID_PLANNING]          AS ID_PLANNING
                   , ESEL1.[DESCRIPTION]          AS DESCRIPTION
                   , ESEL1.[CONTEXT]              AS CONTEXT
                   , ESEL1.[PERIOD_CODE]          AS PERIOD_CODE
    	             , ESEL1.[MATERIAL_GROUP_CODE]  AS MATERIAL_GROUP_CODE
    	             , ESEL1.[DW_DAY_START]         AS DW_DAY_START
                   , ESEL2.[ID_PLANNING]          AS ID_PLANNING_2
                   , ESEL2.[DESCRIPTION]          AS DESCRIPTION_2
                   , ESEL2.[CONTEXT]              AS CONTEXT_2
                   , ESEL2.[PERIOD_CODE]          AS PERIOD_CODE_2
    	             , ESEL2.[MATERIAL_GROUP_CODE]  AS MATERIAL_GROUP_CODE_2
    	             , ESEL2.[DW_DAY_START]         AS DW_DAY_START_2
                FROM [edw_aps_goalpubdb].[ENGINE_SELECTIONS] ESEL1
                     CROSS JOIN [edw_aps_goalpubdb].[ENGINE_SELECTIONS] ESEL2
               WHERE ESEL1.ESEL_CHECKSUM <> ESEL2.ESEL_CHECKSUM
              UNION ALL
              SELECT CAST (2 AS SMALLINT)         AS ESEL_VERSION
                   , ESEL2.[ESEL_UID]             AS ESEL_UID
                   , ESEL1.[ID_PLANNING]          AS ID_PLANNING
                   , ESEL1.[DESCRIPTION]          AS DESCRIPTION
                   , ESEL1.[CONTEXT]              AS CONTEXT
                   , ESEL1.[PERIOD_CODE]          AS PERIOD_CODE
    	             , ESEL1.[MATERIAL_GROUP_CODE]  AS MATERIAL_GROUP_CODE
    	             , ESEL1.[DW_DAY_START]         AS DW_DAY_START
                   , ESEL2.[ID_PLANNING]          AS ID_PLANNING_2
                   , ESEL2.[DESCRIPTION]          AS DESCRIPTION_2
                   , ESEL2.[CONTEXT]              AS CONTEXT_2
                   , ESEL2.[PERIOD_CODE]          AS PERIOD_CODE_2
    	             , ESEL2.[MATERIAL_GROUP_CODE]  AS MATERIAL_GROUP_CODE_2
    	             , ESEL2.[DW_DAY_START]         AS DW_DAY_START_2
                FROM [edw_aps_goalpubdb].[ENGINE_SELECTIONS] ESEL1
                     CROSS JOIN [edw_aps_goalpubdb].[ENGINE_SELECTIONS] ESEL2
               WHERE ESEL1.ESEL_CHECKSUM <> ESEL2.ESEL_CHECKSUM
             ) X1
      ;

    This table cointains quite some recors (in our case 800k) but that is not a problem to tabular.

     

    In PowerBI, i've created these relations, finally you can hide everything in the engine_selections table.

     

     

    Now my 'left' selections are working on the normal fields like CONTEXT, ID_PLANNING, ... the 'right' selections are working on CONTEXT_2, ID_PLANNING_2, ...

     

    If I want a Visual only for the left selections I put ESEL_VERSION = 1 in the visual filter, same for right (=2)

    If I want to see both i just place ESEL_VERSION into rows/columns/legend ....

    Works fine.

     

    Maybe there are far more nicer solutions but i couldn't find articles on it and his one works fine. Our fact table holds over 500M records and still satisfied with performance.

     

    Hope this helps you on the way.

    Anonymous,

    Based on the above description, it is difficult for us to provide you solution. Could you please share dummy data of your table and post expected result here?

      So the idea is that we woudl ahev something like this

       

       

      The 1 is the left (Dim1) and shows wich Selkey records should be selected.

      The 2 is the right (Dim2) and shows wich Selkey for the second selection.

      Dim1 and Dim2 are completely identical except then CompVersion 1 or 2.

      Finaly in the matrix I would like to see only the values for the selected SelKeys, By Compversion ...

       

      Hope this is a bit more clear.

        I did find a solution, without specials tricks, just a design with related tables.

        If anybody would need this, just PM me.
