Dear mhd7,
thats a Topic i struggled quite some time with.
Dashboards look quite simple at a first glance, but in Detail are very complex.
What you have to configure properly is the DataTable to be used for the Dashboard.
You will find it in the Dashboard properties, select DataTable1 (or whatever the Name is),
and there you can select the Location. I usually use "Current Data Table" and place the Dashboard as script into my data table. Then I have to manage only one file.
You also can refer to a fixed Location on Network (but when it isn't valid any more, you fail).
The "magic" is that jmp applies the "source" script to the Dashboard … and recreates the table.
Refer to the example in your jmp Installation:
open("$SAMPLE_DATA/../Dashboards/Instant Dashboard.jmpappsource");
activate "Show properties" under Dashboard Builder
and click on DataTable1 to see its properties.
BR, Georg
