I just upgraded SQL 2005 with SSRS to SQL2012. Everything seems to have gone smoothly with the exception of one thing. The reports that were on SSRS can be ran manually, and the subscriptions can be edited for all except for one batch of reports. When I try to edit the existing subscription for them I receive the following error:
The required field StartDateTime is missing from the input structure. (rsMissingElement)
I can create a new subscription, schedule it, and it runs and processes correctly but I need to be able to edit the current subscription. If it can't be resolved I will need to recreate all the subscriptions, which isn't a huge deal, but am hoping for a less painful fix.
