I have created a data driven subscription and have set up the subscription to send on 28th February only.I have done this by creating a Monthly subscription. I have set February = True within the list of months, and specified "On Calendar Days" = 28. I expected this to run on Feburary 28th only, but it ran yesterday, on March 28th. Can anyone suggest why this happened? Many Thanks,Katie

Hi Katie, Generally, a subscription won't run in a unexcepted day. In this case, could you please help to check "March" is unchecked? Thanks, Jin ChenJin Chen - MSFT

I have checked and double checked that March is not selected. After speaking to a colleague, I find that this happened for them also (i.e. they have a report to send on 28th of February only, and it unexpectedly sent on 28th March). Any thoughts?

I had this same problem as well. We set up a report to run the 1st day of the month on quarter months (March, June, September, and December). The setup was done on 09/23/2011 with a start date of 9/23/2011. The report ran October 1st, but was not supppse too. October was not a month that was checked. I see that there was no follow up by Microsoft. Nice.
