Calculate estimated end item unit-costs of a production order

The end item unit costs are the planned costs of one end item for a specific production order. LN calculates the end item unit costs by means of the estimates for hours and materials (item surcharges included). The calculation of estimated end unit costs of a production order is described in the following paragraphs.

LN calculates the estimated end unit costs when:

  • You change the production order status.

    Depending on the value of the Moment Freezing Estimates field in the Production Orders (tisfc0101s000) session, LN calculates the estimated end unit costs as follows:

    • During Creating Order: When the production order is planned.
    • During Releasing Order: When the production order is released.
    • Before First WIP Transaction: Before the first WIP transaction is carried out.
  • You use the Calculate Estimated End Item Unit Costs (ticst0210m000) session.
  • You use the Print Differences between Frozen and Current Estimated Costs (ticst0411m000) session. If you use this session, the costs are only printed, not stored.

If you print the differences between the current estimates and the previous calculated values in the Print Differences between Frozen and Current Estimated Costs (ticst0411m000) session, LN calculates the estimated unit costs.

The operation costs and the material costs are determined when you create the production order. The operation costs and the material costs of the end item are calculated when the costs are frozen. The data in the Estimated vs. Actual Material Costs (ticst0501m000) and Estimated vs. Actual Hours Costs (ticst0502m000) session are already filled at this moment. LN does the following when you calculate the estimated end-item unit costs:

Step 1. Determines the operation costs

By means of the Estimated vs. Actual Hours Costs (ticst0502m000) session, LN determines the operation costs per end-item unit by using the production times and the operation rates. LN calculates the operation rates based on the total costs of wages, machines, and overhead.

LN stores the operation costs on the cost components. The operation costs are calculated per end-item unit end product. If results are calculated per work center (see the Financial Transactions by Work Center field in the Shop Floor Control Parameters (tisfc0100s000) session), LN calculates the costs per work center. The costs are aggregated in the item-based view of the calculation office by using the aggregated cost components.

Step 2. Calculates the material costs

LN determines the required materials stored in the Estimated vs. Actual Material Costs (ticst0501m000) session. By means of the standard cost price, LN calculates the material costs per component.

The standard cost price includes the warehouse-related surcharges assigned to the item. If the material is linked to another warehouse, you must change the warehouse surcharge part to this warehouse.

If the work center where the material is issued, is stored as a shop floor warehouse, the shop floor warehouse-related surcharges must be taken.

[...]

LN allocates the material to the shop floor warehouse during the release of the order. Even if the calculation is carried out when the order status is not yet released, LN determines the shop floor warehouse surcharge. If the material is of Direct Receipt in WIP type, no warehouse surcharge is determined.

If the cost price is not calculated for a material, LN does not determine material costs.

If you calculate the estimated end unit costs by means of the Calculate Estimated End Item Unit Costs (ticst0210m000) session, you can select the Check Existence of Material Cost Prices check box. If this check box is selected, LN checks whether all material cost prices are available so that LN can make a correct estimation.

Step 3. Calculates the end-item surcharges

After all material and operation costs are calculated, LN calculates the surcharges. The surcharges are calculated in the sequence (item group, item and warehouse level) as defined in the Cost Price Calculation module.

Step 4. Calculates transfer prices

The WIP transfers can only be calculated when, in the Shop Floor Control Parameters (tisfc0100s000) session, the Financial Transactions by Work Center checkbox is selected and the Transfer WIP method is Always or Only upon Completion. The calculated price is the incremental price up to the last operation of the delivering work center.

Example
Quantity Ordered = 100 pcs
Work Center 1
operation 10operation 20
yield %10050
qty plan in200200
qty plan out200100
net mat per 10 pcs1 pcs3 pcs
estimated material qty20 pcs60 pcs
cost per pcs$ 5$ 10
total costs$ 100$ 600
per pcs, per workc.$ 1.00$ 6.00

 

Work Center 2
operation 30
yield %100
qty plan in100
qty plan out100
net mat per 10 pcs2 pcs
estimated material qty20 pcs
cost per pcs$ 6
total costs$ 120
per pcs, per workc.$ 1.20

 

The transfer price from work center 1 to work center 2 =

($100 + $600) / 100 = $7.00

The transfer price from work center 2 to calculation office =

 $7,- + $1.20= $8.20

The base for calculation are all cost price components of material and operation costs. The amounts are aggregated together and stored in a transfer price on the transfer component WIP Transfer Cost Component that is defined in the Production Orders (tisfc0101s000) session.
