What exact steps are producing this error? When you refer to "select the multi values" what does this mean? Multiple members from the same hierarchy? Multiple members from different hierarchies? Multiple attributes? Multiple levels? Multiple measures? Some combination of these? Where are you trying to insert the selected objects? In a crosstab? A chart? Which specific part of the reporting container are you trying to insert them into?

Lots of questions, sorry.

MF.
