I am creating a SharePoint 2007 custom sequential workflow in which I am assigning a single task to 2 different users.The task is approval of an expense report.
I am facing the problem when 1 person approves the expense amount and the other person rejects it. This is a classic workflow issue.
I want to lock the assigned task or make the task read-only as soon as 1 user approves/rejects the expense amount preventing the other user from changing the approval status.
Please Help.Thanks in advance.
