| Calculating operation costs (labor, machine, overhead) |  |
| Labor, machine, and overhead costs are calculated to determine the operation costs. If the work center is either a main work center or sub-work center, ERP LN first checks the setting of the Type of Operation Rates field in the Cost Price Calculation Parameters (ticpr0100m000) session. If the parameter value is Work Center Rate, ERP LN reads the work center's operation rate code. A number of labor, machine, and overhead rates have been recorded using the above-mentioned operation rate code for the selected cost price calculation code in the Operation Rates (ticpr1150m000) session. Based on this data, ERP LN calculates the labor and machine costs required to carry out the relevant operation using the following formulas:
    Labor costs = man hours	x labor rate
    Machine costs = machine hours x machine rate
Depending on the method used to calculate overhead costs (set via the Operation Rates (ticpr1150m000) session), ERP LN calculates the overhead costs on the basis of the man-hours or machine-hours. This is done using the following formula:
    Overhead costs = man-hours or machine-hours x overhead rate
According to the direct costing principle, no overhead costs are included in the cost price calculation code. The operation costs for the operation comprise labor, machine, and overhead costs. If the Type of Operation Rates field is Task Relationship Rate, ERP LN reads the task's operation rate code and goes through the same cycle, as described above. |
