Send a parameter through a enhanced screen

Hi everyone,

I have been trying to send the value that has a specific field of an enhanced screen to be able to use it in a custom screen. To do this, I added a button to a section group of the enhanced screen. However, when I had to specify the OBN Information I don't have any way to specify the parameter that I want to send to my custom screen.

When I define the OBN Information of the button I have to specify the BO that I want to reference. However, I am not be able to indicate any type of parameter to be sent to another BO.

The configuration of the button from an enhanced screen is very limited, so I would like to know how can I send a parameter from an enhanced screen to a standard screen (e.g. my own QA)

Best Regards
