I do this in my dashboards all the time. Here is an example where I have a drop down box populated by a BAQ. I adjust the parameters for the BAQ based on another textbox or drop down box.
I would avoid the customization and just do this in the BAQ. You can make the fields update able, but don’t actually make it update-able in the dashboard. Then it will automatically be a drop down filter in the dashboard without customization.
Thanks for sharing this, this has been a major help!
So far got the drop-down / customized the tracker view but I’m struggling to see how to get the tracker and the grid to communicate - currently when I select something in the drop-down of the tracker, the bottom grid doesn’t filter. Should I be setting something up in the Properties, either using the Filter or Parameters tab please?
