RQM: group by for multi value category buggy?

we want to group by for a multi value category but this seems not to work as expected:


I would expect to see a group like "SW-Component, TCU-System(nearly)",
but only the first assigned value is used as group by criteria.

1) ill this be fixed in a future release (we have 5.0.2)
2) Is there a god quick work-a-round to get a statistic about distribution of the values?

 thanks Jörg

I got an email with an answer, but it seems it was not saved here. Hence a copy...

 Hi Dong,

I think the main effort is sorting the data. And sorting is already possible by multiple attributes. Why not also sort by values of a category?

And not all 2^n  combinations (unassigned is also a valid combination) must be visible, only the really used combinations.

Anyway, from user point of view it is a must have if a multi value category is offered as group by attribute. Otherwise a group by makes no sense and leads to wrong conclusions (already happened in real project :-()

  Thanks, Jörg

The reason I deleted my original answer is that I thought of the exact sorting theory (not sure if done in DB or RQM) that you mentioned above after posting, and believed my answer was not appropriate. I am with you on this. :-)
