Bonjour Naomi,
Thank you for your help. I tried the "classic" solution ( SET REPORTBEHAVIOR 80 ) but it doesn't work. I looked further and I noticed a very high network activity while the preparation of my report. My report was built around different files linked together with some "set relation to..." So I changed my approach and generated a single SQL cursor and I modified my report to reflect that change. This was the solution.
I'm surprised how the "set relation to..." made a so big difference from one version to the other.
Thanks again,
Normand
Have a nice day,
Normand
