I am trying to create a KPI in Dashboard Designer, but am getting a timeout. I have been doing this for a while on my site; this is not the first. I haven't had this problem before.
I created a new KPI and clicked on the Data Mappings column value, which is a hyperlink, to bring up the Dimensional Data Source Mapping dialog. I switched to a Data Connection in the site I just created (DC works perfectly and can retrieve sample data). When I click the "Select a measure:" drop-down menu, I get the message "Loading..." and after a while (a minute? two?) a dialog pops up with:
The request took too long to complete. SharePoint is currently unavailable or experiencing heavy traffic. Try again later.
This is a test SP server and I'm the only one on it, so there is no load. Also as mentioned, I am able to verify the Data Connection without problem. I am not having any issue with any of my other few dozen KPIs/Data Connections. Any suggestions as to how to troubleshoot?
