Scenarios when a Webi Schedule fails

Hi Gurus,

Can someone please share all the scenarios when a scheduled report fails.

Recently one of schedules failed which was scheduled (using Windows AD details) to a shared drive using my Windows AD details. I think my Windows AD password was changed around that time.

Also during that time i changed the folder of the report. But i am not very sure which of this caused the issue.

So likewise i wanted to know all the scenarios when a schedule fails.

PS: i have the admin rights.
