Currently, the system calculates percent salary based on the main driver’s tariff, which causes incorrect calculations for co-drivers when they have different per-mile tariffs. This was discussed in the dev meeting, and it was decided to submit a feature request: the system should be updated to calculate percent salary individually for each co-driver based on their assigned per-mile tariff. The customer is requesting this be implemented soon, as they need to pay drivers at different rates, and manually adjusting the percent salary each time would be a hassle. Please check and do the needful.
