The transfer route costs option in the assemblies module can be used to calculate the total overhead and labour costs for a route and transfer the totals back into an assembly:

The details of each assembly contain a typical batch size. This is used to calculate the costs of each operation as follows:
| Total Time Per Item | Operation Time Per + ((Setup Time + Setdown Time) ÷ Typical Batch Size) | 
| Overhead Cost For Operation | Total Time Per Item x Overhead Rate | 
| Labour Cost For Operation | Total Time Per Item x Labour Rate | 
The costs for all the operations in the route are calculated in this way and the totals passed to the Assemblies module.
