Hi,
"Cannot perform the intended action on this document. (WIS 30650)"
This webi error can be triggered if you attempt to open a new version of webi report on a older version of BIP WIReportServer/webi rich client.
For example, if the webi report is developed with BI4.1 SP02 Patch02 client and somehow if got export into a BI4.0 SP08 Enterprise, you'd run into this WIS 30650 error if you try top open it on BI4.0 SP08 BILaunchpad.
Hope this helps,
Jin-Chong
