Trash Can and Deletion flag set CJ20N

Hi,

what is the difference between Trash Can and Edit->Status->Deletion flag-> set   in CJ20N, i need to do different activities when clicked on Trash Can and when Deletion flag is set .

I'm using user exit   EXIT_SAPLCNAU_004

to catch deletion. using SAP_ACTVT = '06'.   but the program is catching SAP_ACTVT = '06'. for both.

what feild value will get me, what is clicked?

Thanks!
