D365 Finance and Operations - Expense Mileage

Default mileage rate can be set at the expense parameters:

Mileage type expense categories can be set up and optionally mileage tiers can be set up at:

Mileage tiers can be defined per mileage expense category:

Mileage rate tiers can be defined for miles or number of passengers and can be date bound as well.

 Once the employee books the mileage, the system picks the applicable mileage rate into the expense line. If the employee puts a lot of mileage in one expense line, which covers many tiers, the system splits the expenses lines accordingly intelligently for you.

In the expense report below I did create only two expense lines but they were spanning across multiple tiers. System split them into 4 lines and posted the mileage rate accordingly.

When the mileage is posted, then the same gets recorded against the employee at:

That’s how the system knows how many miles are claimed against each tier for each employee.

The only thing that is not correct is the ‘New’ button on this form. I think that is there to manually enter the miles claimed by the employees in the exceptional scenarios where the system fails to do so.
