| Assembly Order CostingCosting is a crucial aspect of the Assembly Control module. The manner
in which costing is performed depends partially on how you define your cost
components. Other aspects of costing that are described here are: - Transaction-processing
methods
- WIP transfers
- Calculation of final
results
- Differences between Assembly Control module
costing and Job Shop Control (JSC) module
costing.
- Where to view financial
data in the Assembly Control module.
Note The aspects of
financial costing that are described here have no relation to the theoretical,
mathematical costs associated with line sequencing. Cost components There are three types of cost components: - Materials
- Operations
- Surcharges
Cost components can be
posted on an aggregated level, detailed level, or on a combination of
aggregated and detailed level. When costs are posted on an aggregated level,
all the costs for a cost component are combined into one sum, such as all the
individual material costs being added into a single sum. To post cost
components at a detailed level, you must define cost component charts. Detailed
cost components result in a price structure in which all costs have been broken
down. Transaction-processing methods The Assembly Control module is intended for use by companies that produce many
variants of complex products in a flow-assembly line. Assembly Control can also
be used for low-volume assembly if you select Order Based transaction processing. Select your transaction-processing
method in the Transaction Processing field in the Assembly Control Parameters (tiasc0100m000) session. - Use Line Station Based transaction processing when you do not need to trace back to the
original assembly order. Costs are posted to the assembly line. Results are
calculated by period by assembly line.
- Use Order Based transaction processing when you want your costing performed on
the basis of individual assembly orders. Costs are posted by order by assembly
line. Results are calculated by order by assembly line.
WIP transfers WIP transfers consist of: Generating the transfer order A WIP transfer
generates a transfer order. However, if the transfer occurs between line
stations that are in different logistical companies, a sales order and a
purchase order are generated. Performing the material issue A WIP issue may
unblock or immediately process the transfer warehousing order, dependent on
your parameter settings. In multisite situations, the normal sales procedure
must be followed in order to ship the goods. Performing the receipt A WIP receipt
acknowledges the receipt of the WIP transfer order at a main assembly line that
has received work from a supplying assembly line. Warehousing processes the inbound
line automatically. If the assembly lines are from two different logistical
companies, it is necessary to use sales orders and purchase orders (rather than
WIP transfer orders). In multisite situations, the normal receipt procedure
must be followed in order to receive the goods.
You can select whether you want these processes to occur
automatically, semiautomatically, or manually. Calculation of financial results When you close an
assembly line with the Close Assembly Lines (tiasc7220m000) session, the production results of the line are
calculated. All the line station orders must have the status Closed. The financial results are the WIP transactions
(which are estimated costs) minus the actual costs. Differences between costing in Job Shop Control and Assembly Control - In Assembly Control, the
quantity completed is always one.
- There is no scrap and yield in Assembly Control.
- WIP transfers are only
created between different assembly lines, and not
between line stations (of the same line).
- There is no set-up
time in Assembly Control.
- End item unit costs
(estimated material costs and hours costs for an order) are not calculated for
an assembly order. This is not necessary because each end item uses the same
assembly line, so there is no point in creating separate surcharges for each
item.
- In case of Line Station Based transaction processing, variances are calculated for an assembly
order and not for a generic item.
- Production results are
not split into price variances and efficiency variances in Assembly Control.
- Financial results in Assembly Control are
posted to the cost component of the
assembly line.
