Picking up the changes outside the current workflow's key fields data

[Ricky Lee]

Hi Everyone,
 
Just wondering is it possible to set up a Wait for Event that will pick =
up the changes made outside the current workflow's key fields? E.g. In =
my Recruitment Workflow, Applicant A and B both apply for same vacancy. =
I need to terminate the Applicant B workflow when Applicant A receives =
the contract offer and fill the vacancy position. soo I want to find out =
whether it is possible to set up a Wait for Event that will pick up the =
changes (when Vacancy is filled).
 
I am on 46C.
 
Any help is appreciated
