Engineering Definition of Manufacturing Specific Components

      Disclosed are methods which control manufacturing specific
component substitutions by a company's engineering group, and the
distribution and processing of those substitutions into the
appropriate manufacturing views.  Essential elements of the methods
include:

1.  Assignment of the Component Substitute

    Each bill of material component in the design view may have one
    or more component substitutes.  The following rules apply:

    a.  Updates to the component substitute are version controlled
        using the same rules for control by engineering change.

    b.  The logical key of the substitute item object is the Build of
        Material (BOM), Item Number, BOM Component Item Number, BOM
        Component Sequence, and Substitute Location ID.  The only
        data field is the Substitute Number.
    c.  The Location ID must identify a manufacturing location.

2.  Distribution of Substitutes

    The engineering view of substitutes is distributed.  Resolution
    into local manufacturing views is done at accept.

3.  Processing of Substitutes into the Manufacturing View:

    The following rules apply when a BOM component is accepted into a
    manufacturing view:

    a.  The component item will be replaced by the substitute item in
        the BOM component and all related dependent objects.
    b.  Substitutes will not be copied to the manufacturing view.
    c.  All dependent data related to that BOM component (optional,
        operations, and restructure) will be updated to reflect the
        combined effect of any update to the BOM component itself and
        its Substitute Number:

        1)  Substitutes are processed along with their "parent" BOM
            component, and other dependent objects in the engineering
            view (e.g. optional).
        2)  These records all have the same data elements in the high
            order part of the logical key.
        3)  They are processed in the order BOM component,
            substitute, other engineering dependents.
        4)  A check is made for each BOM component to see if its BOM
            Component Item Number is affected by a substitute on the
            Manufacturing view.  This is complicated by the fact that
            there are several possibilities for the EC affecting the
            BOM component and/or the substitute.
        5)  For each BOM component "applicable at" (includes
            "inserted by") or "extracted by" the EC to be accepted
            (these are the BOM components which can potentially be
            updated during the "accept" processing) any substitute
            objects are selected which s...
