Hi,
Approve can happen at any time period open or close.
Reject Can happen only at period open only.
if user want to reject and if period is close then we need to send mail to adminstartor open period.after opening of that period user can reject that document.
so untill that period is open we need to keep that user decision step in his mail and we need to check period is opened or not.
but how to check that condition period is opened or close by adminstrator every time.
Thanks,
phani.
