I zoom to a another session from a session & when close the session,it will take much time (20 to 25 secs.).

Can any one suggest ways to resolve this problem.

So are there specific sessions with this problem? Is it all zoom sessions? Is it zooming off the application menu or a zoom field?

This problem is only with single session. Also it is a zoom session. It is zoomimg off to zoom field.

If it is only with 1 session I would recommend running update statistics and maybe even running ttaad4225m000 repairing reference counters. Of course you might need to this on all the tables related to the two sessions. If that does not fix it then contact baan support. You can also turn logging on to see which query maybe causing the problem.

Good Luck!
