The following rules apply to both calculations:
- The overhead field of work orders is not a formula definition field.
- The Planned Overhead field of work/production orders is equal to transaction totals on the Planned Overheads tab.
- Resource costs are calculated by processing the cost factor of shifts/exceptions of Resource Usage records.
The following rules apply to planned cost calculations:
- The cost of related materials used in Planned Production Order Cost calculations are entered into the Unit Price fields of planned Usage, Scrap, Input from Production and Warehouse slips. The Cost of Input Materials option located on the Planned Production Order Cost Calculation window is used to specify the cost to be used in calculation. This field contains two options:
By Company Costing Method: The cost value calculated using the company costing method is used for cost of input materials.
By User Options: The value selected on the costing method field on which planned cost is displayed as default is used for cost of input materials.
If Production is selected on the procurement type of an input, the planned cost value is equal to the Planned BOM Cost calculated for the related period.
If Purchasing is selected on the procurement type field, the planned input cost is the planned cost defined on the material for the period.
When other costing methods are selected, values are assigned according to the moving cost method.
- Costs are assigned to warehouse slips using the company costing method and by processing previous planned inputs. The same method is used for pseudo semi finished good usage transactions.
- Costs and unit prices of inputs from production are calculated by calculating total costs of production orders grouped by BOM and revisions, and distributing the calculated totals to input from production transactions linked to related work orders using cost factors.
- Total cost that covers total material, workstation, labor and overhead costs of work orders linked to related BOM and revision is calculated.
- Planned input from production transactions are determined for work orders linked to related bills of material and revisions.
- Results obtained by multiplying input from production quantity in main unit for each transaction with the cost factor are aggregated.
- Cost rates of each Input from Production are calculated by dividing the result of quantity (in main unit) ** cost factor* operation to total (T).
- Total cost of each transaction is calculated by multiplying cost rates with total cost. Unit costs in main unit are calculated by dividing the calculated total cost to transaction quantity. Calculated unit costs are converted to the unit on the line.
Actual cost calculations are performed using the same method defined above.
