The allocation of
assembly parts is based on product engineering. Allocation using product
engineering is a fast but approximate material requirements calculation method.
The number of assembly parts for each engineering module is calculated using
demand from real sales orders and hypothetical 'pseudo orders'. An engineering
module is a group of standard parts, without routings, assembly lines, options,
and so on, for a particular system, such as the electrical system or
transmission. An engineering module is not actually manufactured and is for
design and planning purposes only.
Process Engineering Quantity
The allocation of
assembly parts is based on process engineering. LN calculates the
requirement for assembly parts using all the relevant data for the assembly
line, including option combinations, product structures, and so on.
Maximum of Both
Whichever is larger of Process Engineering Quantity and Product Engineering Quantity is used for assembly part allocation. Using the
maximum quantity enables you to compensate for possible errors in the
calculation based on either of the previously mentioned processes.
