This sounds like ServiceNow… if it is I’d love to know that special URL.

Or you can type “cancel_my_transaction.do” in the navigator filter bar. Related tip: you can quickly bring up any table by typing “table_name.list” (s/.do/.list/ from the single-item url) there instead of poking around for a link. “sys_user.list” is probably the one I use most often.
