How to get data from different BO in ByD

Hi Experts,

I'd like to show some data from the other BO(there is just BO no screen) to the screen of main BO (BO has created screen)

as can see pic above, i want to get data from Preventive BO to show on the interface

they are the same element.

I don't know if i can do that?

Best Regards,

Thanarat
