How to use CX_BO_ACTION_CANCELLED with FM POPUP_TO_DECIDE_LIST ?

[stephane]

Hi Mike, 

You are right it is much more simple to use than described on the SCN
link I provided.
No need for the returning parameter, no need for a terminating event,
wonderful. 
Thanks for replying I should have made the test before reading the SCN,
unfortunately I was in a hurry... But not today so thanks again 

Cheers
Stephane
