OM Documents (1022500) - Run code when change Tab

Hi all,

Currently I'm working on customization of OM Documents (10.225.00). Based on my testing, by standard, when we click on "Refresh Sales Orders" button, record will display in Sales Orders tab. Then, when we directly click on Shippers tab, this screen will auto load record into Shippers grid without need us to click on "Refresh Shippers" button.

So, my question is how can we customize to set the screen to run code upon click tab? Because I have a extend table that need to show some record into Sales Order and Shipper grid.

Thanks,

AY
