Finding what the report subscription error is in SSRS

Question

I've created a simple report in SSRS, and then tried my hand out with a data driven subscription.
I can verify that the subscription runs on the 'My Subscriptions' page, but under status it says there is one error.

How do I find out what this error is?

Answer 1

Are there any interesting entries in the windows event logs and SQL Server logs?

Answer 2

received this answer from stackoverflow which helped me find info on the errors:

You need to look in the "Report Server Execution Log" which is a particular SQL Reporting Services log file.

See Reporting Services Log Files for details.
