OTBI Report - Hyperlink Path Not Found Error

I'm getting a "path not found" error when clicking a hyperlink on a graph in my OTBI report. The hyperlink is supposed to open a customer profile report when I click on a customer name in the graph.
here is a screen shot for reference:

where can i check the path that the hyper link is defined (i got the same dashboard and its working fine but its not working when i am changing the dashboard name + it is requested to change the dashboard name)
