Configuring rates for driver journal

Hi community.

We are running a 6.4.2 cloud implementation for a customer in Argentina.

This customer have a DC located in Buenos Aires and distributes their goods to their multiple facilities in the metropolitan area.

Transportation scope is as follows:

Nbr of Service providers = 5

Payment terms= fixed amount (example $7500) by journal of 8 hs work.

Complexity of this scenario is given by the fact that a same driver – equipment can perform more than one shipment within those 8 hrs. Any extra hour above those 8 is considered additional charge.

Rates could be daily or nightly (starting at 15:00 hs) and we also need to verify if the driver worked 4 hs or less to charge half journal.
