If you want to create material cost estimates or costing runs
based on the same quantity structure, you can reference existing
cost estimates. This enables you to make constructive comparisons
while at the same time improve performance.
To do this, you can define in Customizing for Product Cost
Planning a reference variant and enter
this in the
costing variant . The reference variant enables you to
specify whether certain items should be transferred as already
valuated or whether they should be revaluated.
You can use an existing standard cost estimate as a reference
for an inventory cost estimate. The system accesses the quantity
structure of the standard cost estimate without determining it
afresh. You can use the reference variant to establish that
overhead should be calculated differently, for example.
You have executed a costing run in the legal valuation view in
costing . You can use this run as a reference to carry
out costing runs based on the same quantity structure for both the
other valuation views of the group cost estimate.
For percentage overhead costing of
materials, it is necessary to use the reference variant in order to
compare the results. This enables you to receive valuations that
differ only in the transfer prices. As a result, you improve
performance, because the system does not have to determine the
quantity structure again.
