Add running sum function to crosstab. User should be able to set in desinger:

We already have running sum function in crosstab. But as to the two requirements, I don't quite understand. Can you give an example to show the case ? Thanks.

Whenever I try to use running sum on crosstab (2.6.1) I get the following message:  "Aggregation on cube measure can not be such type: "RUNNINGSUM" I will add some attachment with more detailed description.

Running sum in crosstab - aggregation orientation and partitions

Simple example of running sum aggregation in crosstab. This kind of aggregation/partitioning would be really useful in financial management (PL by months/years) or in projects performance tracking.
