Data Driven Modelling - only one DATE dimension possible?

    Data Driven Modelling - only one DATE dimension possible?

    Hi,

    I need a cube with to date dimensions
    - date_beginn
    - date_end



    After a click at the "Data Driven Modelling" button in Excel I get "Duplicate time column: LP_BISDATUM[date, yyyy-MM] as failure.

    Does Data Driven Modelling only support ONE time dimension?
