Hi Sreekanth,
Thanks for the reply. This is the issue I have is that I do not know when the FM will be called.
I would like to add some F4-Help drop down list to fields: Main Group (PRODH1), Group (PRODH2) and Subgroup (PRODH3).
The program name is RMCA7019. The screen number is 1000 and the screen fields are SL_0001-LOW, SL_0004-LOW and SL_0005-LOW.
Here is a screen shot of the selection screen just in case
Thank you in advance for your help.
Sylvain
