Controls in Trip Simulation

The system applies several controls to protect the costing process.

Duplicate Expense Control

The same expense cannot be added more than once in the Trip Expenses Outline.

Example:

Depreciation cannot appear twice in the same Trip Simulation.

Route Expense Limit Control

Trip expenses cannot exceed the predefined amount or calculated limit from the selected Simulation Route. This prevents users from over-expensing trips beyond approved route rates.

Payable Expense Control

Only expenses marked as payable in Fixed Expenses can be converted into Purchase Orders.

Duplicate Purchase Order Control

Once an expense row has been used to create a Purchase Order, it is linked to that Purchase Order and no longer appears in the payable expense selection dialog.

If all payable trip expenses have already been converted into Purchase Orders, the system displays:

All Trip Expenses Paid
