FM to give into a selection screen a directory on your own PC

Hi dear experts,

I'm searching something similar to KD_GET_FILENAME_ON_F4 FM, but, instead of choosing a file in AT SELECTION-SCREEN ON VALUE-REQUEST FOR..., I would like to choose only a directory (as "Desktop"), since after that, filename has to be decided from pgm code itself...

Let me know if you need some more inputs...

Bye,

Roberto
