Approval of vacation requests according to the dual control principle

When processing a leave request on the dashboard, the option of a dual control principle should be introduced.

As soon as the line manager presses "Accept", the request is no longer visible to the HR department and vice versa.

However, an HR department cannot know in case of doubt whether the leave request has been approved and a line manager cannot know in case of doubt whether the leave request has been submitted correctly (remaining leave, correct wage type, etc.).

Therefore, the possibility of a dual control principle is urgently required here.
