Dear all,
I have a new issue using Dashboard.
I have created a graph using many Kpis with a join. Once it is ok, I realize I missed on KPIS. The problem is that I have to make again a portlet by defining a new data source. And after that, I have to include this new portlet in place of old one. This is not friendly, and now, I have a list of portlets and data source not used.

Can someone tell me how to change the data source definition ? How to add a new KPIS ?
Thanks in advance.
