Memory exceeded running a simple query

Hi gurus,

I'm facing a pretty annoying issue with Analysis on Excel.

I'm trying to run a report with 89774 lines and I get a memory exceeded error message.

The report runs fine with RSRT.

I ran it to get Statistics and there is something strange about it:

I don't understand why the system transfers 1 795 480 lines, but I think this is where the issue comes from.

My query is made of 31 characteristics and 20 key figures, with no formula.

Has someone already faced this problem?

Thanks and Regards,

Jean-Guillaume
