Approval matrix

Summary:

We have a requirement for a specific approval matrix to be defined for an Unpaid Leave

Content (please ensure you mask any confidential information):

The requirement is as follows:

Leave Type                                                : Unpaid Leave

Total entitlement / year                          : 60 Calendar days (Jan to Dec)

If Leave applied < 15 days                        : Approval = Line Manager > Head of Department > HR HOD

If Leave applied >= 15 days                      : Approval = Line Manager > Head of Department > HR BU Head

We are aware that the above can be achieved with 2 rules. However, the problem statement is mentioned below:

If total entitlement consumed = 15 days, then 16th entitlement onwards (either applied for less than 15 days or more than 15 days) then Approval = Line Manager > Head of Department > HR BU Head > FYI to HR HOD.
