Is there a way to copy an event? I need to modify one and want to have the original one to reference.

Release:
Component: ESPWA

When in an event you can create a new event by editing the event you want and then changing the name of the event. You will now see one in your event lists of the new name and the old one still remains. 

EXAMPLE: Event named BABRI02.TESTRUNE below. I will change the TESTRUNE to TESTRUNE1. 

/*************************************************/ 
/* DEFINED BY BABRI02 AT 15.00 ON SAT 8SEP2018 */ 
/* LAST RUN AT 09.43 ON THU 31JAN2019 */ 
/*************************************************/ 
EVENT ID(BABRI02.TESTRUNE) MAILBOX(BABRI02) SYSTEM(X114M) REPLACE 
INVOKE 'BABRI02.ESP.TESTPROC(TESTRUNE)' 
ENDDEF 

Now when I list the events you will see both of them. 

EVENT NEXT DUE AT LAST RUN SYS HC SC 
BABRI02.TESTRUNE REQUIRES TRIGGER 2019/01/31 X114M 0 0 
BABRI02.TESTRUNE1 REQUIRES TRIGGER UNKNOWN X114M 0 0
