Drill history should drill down to base level automatically
Drill History Right now only delivers values when all dimensions are set to base Elements. So users can only see the history of a cell when all base Elements are known. That is very unlikely and is in contradiction to the usage of the flexible cube layout when only relevant Dimensions are given in PALO.DATA using PALO.EL()
Drill History should rather work in the same way as drill thru and drill down C-Elements automatically.
