Hi Rayner,
You are most welcome.
Unfortunately I could not resolve the issue, so we have dropdowns with static value and we regularly keep a check if there is any discrepancy.
I developed a Z t-code where I first called
FM to read DDIC table level help, if that fails, read Domain level help, if both fails naturally you can't do anything. However, if any one works you get the list.
There are two problems.
1. You have no control on Search help. Like this method returned list of all PERNR. Ni choice of search by Last Name etc.
2.I called this Z transaction as a web transaction and passed field name needing F4 help as a parameter. This transaction appeared as a pop-up. But you cannot force user to read value from that ONLY. Also there is no way to ensure, whatever user selects will return to Personas.
So I left it there. Now I am planning to implement same design through HTML, JS and WS. It won't be very flexible but perhaps it might be useful.The idea is, call a modal window from Personas. This window will have a webpage that will accept Search Help name from Personas an then will call a Z web service which will return the output of SH. The page will then write the output as a table and when user clicks on a value, it will go back to parent control.
Now all this is @ conceptual level. I don't know how much of it will work in Personas.
Hope this will help you.
Regards
Abhijit
