Hi alexandraMiz,
What you just described sounds like a bug to me so I'd make sure to let support know about it via a ticket.
It could even be that it's already a known issue and if lucky, already fixed in a later version (not sure what version you are on).
As for workarounds, what you could do is to write a data set business rule that triggers the FdxExecuteCubeView function (which returns a data table object) and use vb.net to apply any changes to description etc you need to the table.
You'd then call this dataset rule from the Data adapter and feed that to BI Viewer.
Hope that helps.
