Find transaction code from customer exit (include program)

Hello,

Is there any way to find in which transaction a customer's exit include is used ?

For example the include "ZXCOFO01" .

I go to SE38, and paste it. then from the menu Utilities -> Main programs, it shows me the program "SAPLXCOF" which belongs to the function pool XCOF (Customer Exits Order Confirmation CORF)

Now, how can i find in which transactions is used ?

(where used function doesn't show any transactions)

thanks in advance
