Hi,
I believe this pending issue is addressed and fixed on XIR2 SP6. See ADAPT01177040
Description:
In InfoView, when an instance of a Web Intelligence document is scheduled to a particular time in the future the instance fails to run.
The status of the instance remains as Pending.
New Behavior:
This problem is resolved.
If your XIR2 is before SP6, I'd suggest you to apply the SP6 upgrade and FP6.4.
Hope this helps,
Jin-Chong
