RF framework list for a specific field

[former_member687281]

Hello!
This is my screen:

My requirement is to make a list for the marked field.
My problem is: This field is only for output and my employer wants it to stay this way so it has to be only for output.
He also said that they don't want to select the field for the list.

So, the goal is to make a list for the marked field and whenever I press the F8 button on this screen no matter where the cursor is, it should display the list for the marked field on the picture and when we click on one the list element it should change to that.

I know how to make a list with
/SCWM/CL_RF_BLL_SRVC=>INIT_LISTBOX (field name)

/SCWM/CL_RF_BLL_SRVC=>INSERT_LISTBOX (field name, value, and text

But it's only working for the seleceted field.

Please help me solve this problem.
Thanks in advance!

The requirements changed, so it's good if the field is also an input field an needs to be active. I can do that.

But if someone has an answer for the original question I am still curious if it's solvable.
