Thank you for your kind reply.

In fact all documentation is in their page..i was so stupid...:-)

I read it and i was able to registry their assembly.

I was also able to change columns order using these ASSP libraries...

I solved all my problems creating a normal ACTION (i read their examples)...

I was able to :

Change Order columns

I can run an action also over a calculated measure not only over a standard measure

I can change the name of the columns with a more friendly name..

I think their very good...

I.E

ASSP.GetCustomDrillthroughMDX(

"[Vendite].[Importo Venduto] as [Importo Venduto]

,NAME([$TessereClienti].[Codice Tessera]) as [Codice Tessera]

,NAME([$TessereClienti].[Codice Tipo Tessera]) as [Tipo Tessera]"

)

There a lot of ASSP useful for generic problems...not only DRILLTRough..

I suggest to you to test them...

Thanks again.
