    Anonymous,

    It seems that you hit the limitation which is described in this official article, it is not possible to use an aggregate function over a table in DirectQuery mode and it is not possible to change the aggregation for a column.

    Besides, currently, this new DirectQuery mode of SAP connector is available as a Beta feature, with the main goal of gathering customer feedback about overall capabilities and performance. Regarding to your issue, click "send a frown" button to report it.

      Lydia,

       

      Can I ask something about the plans with the directquery option towards SAP-BW ?

      Not for immediate use but a real design issue towards the future.

    I'm connecting to a SAP BW with directquery.

    Using the $INFOCUBES.

    Connection works fine (but slow), normal visuals are working fine.

    Now I'm trying to add a Measure

     

    Measure SelCount Table = COUNTROWS(Stamkostenplaats)

    This works fine on a normal 'Table', but when the tables contains Hierarchies it goes bananas and I can't find a way to have it defined correctly.

    When trying to have it defined by a distinctcount on a field

    Measure SelCount Jaar = DISTINCTCOUNT(Stamkostenplaats[[0MAST_CCTR                    2020NMBS/SNCB]].[LEVEL03]].UniqueId])

    Whatever I try, always getting erros in the visuals ...
