Hi Carlos, the default memory limit for olap server (memsize) is 512 megs.
If your olap server is running on windows look for the file sasv9_OLAPServer.cfg and increase the memsize setting from 512m to 1024m (1 gig).
Example:
you find: -memsize 512m
you change in: -memsize 1024m
You must restart the olap server service (on win) to force the new value for memsize.
If this doesn't solve your problem, please contact SAS Tecnical Support.
Regards.
Andrea
