It would be nice if there was a way to get reporting out of Patch Manager based on SCCM data. The including MS reports stink and when you run Patch Manager reports against WSUS it is not consistent with what has been approved/deployed through SCCM.
Also on the reports front, it would be nice if you could publish custom reports created in the Patch Manager console to the Orion 'Patch Manager' site. The options currently available on Orion are extremely limited and not exactly useful.
I think there was a company called Silect, that had an SCCM patch reporting product in the past, but I don't know if they still offer it or develop it.
