I'm seeing the following errors in my SCSM 2012 CU3 environment on the DW management server:
Event ID 33528
Message: Unable to connect to DataSource : DW_PPS_SCSM_Managers. Ignoring this datasource for MP Sync.
The reason for me manually doing it this way is because trying to "unregister" from the Administration console fails, and I believe it's due to the fact that one of my data sources has spaces in it, so it doesn't parse the spaces correctly and fails
with an error.
Unfortunately, after re-registering with the DW, I'm only seeing one Data Source. I'm missing the DW data source... and I'm not seeing anything in the Reporting section (yes I manually configured the remote SSRS server.)
