Dear Expert,
I met a problem of how to handle an event raised by a free programmed search help - (F4), and this F4 is invoked
by a field defined in a Selection Option component (WDR_SELECT_OPTIONS) - SO.
The scenario is that I would like to update the SO after the user multiple select some entries in the F4. I could tranfer
back all the value chosen in the F4 to the consumer SO, but I can not update the icon in the SO(e.g in SO, multiple values will be
displayed with a green arrow icon), because I could not define a handler in SAP standard component SO, and it looks like there is no chance to catch the event triggered at the end of selection in F4. (this event belonged to this F4)
Welcome any suggestions or ideas, Thanks very very much.
In Addition, I use this way to enable the F4 for SO
lo_so_component->create_cmp_usage_group(
name = 'F4_TRANSPORT'
used_component = 'ZTRANSPORT').
