Adding Parts with Associative BOM Links
If you want to add parts with associative BOM links, you must first set the following Windchill preference:
Pasting Parts must be set to Paste with Associative BOM Links
In addition, the following Windchill preferences govern the appearance of the BOM transformation panel used to set additional transformation options in the action window and should be set accordingly.
 |
If none of these preferences are set, then associative BOM links are automatically created using default system values.

Show BOM Transformation Panel for Assemble as Selected Part
|
If set to false the BOM transformation panel does not appear. By default any existing downstream equivalent part is added to the structure. If there is no existing downstream equivalent part then the selected or copied part is added to the structure.
|
|
Show BOM Transformation Panel for Assemble as New Branch
|
If set to false the BOM transformation panel does not appear when Paste as New Branch and Assemble As New Branch actions are launched. By default a new branch is created from the selected or copied part using the default view of the downstream view.

Branch Attribute Propagation Behavior
|
Allows the user to specify which branch attributes are propagated when performing certain BOM transformations when duplication with propagation" has been enabled. The following options are available:
• View Only: The view attribute is propagated down to the leaf node, while BOM Type and Alternate BOM are propagated to the top node only. This is the default setting.
• View and BOM type: Each iteration created in the downstream view by the BOM transformation has the View and BOM Type entered during the transformation.
• View and Alternate BOM: Each iteration created in the downstream view by the BOM transformation has the View and Alternate BOM entered during the transformation.
• View, BOM type and Alternate BOM: Each iteration created in the downstream view by the BOM transformation has the View, BOM Type, and Alternate BOM entered during the transformation.

Adding parts with associative BOM links is used when Transforming an eBOM into an mBOM. During this process positional information from the upstream BOM to the downstream BOM is maintained, as are the associative links between the parts being added.
When adding parts with associative BOM links, the following link creation rules apply:
• If the two parts are non-equivalent parts then no occurrence links are created.
• If the two parts do not have paths associated with them, no occurrence links are created.
• If the two parts have equivalent parent parts they are displayed first, and you are given the option to Add Existing Downstream Part. However, if you do not want to add the existing equivalent downstream part you can select Add New Part when using the Paste as New Part or Assemble As New Part actions. Or you can select New Branch when using the Paste as New Branch or Assemble As New Branch actions.
• Consumption links are created.
|
|
If there are multiple existing downstream iterations as a result of the transformation performed in these actions, you are asked to choose which one is launched as the root node in the downstream tree.
|
You can add parts with associative BOM links using one of the following methods.
• By Creating a New Branch.
This creates a new branch iteration of the selected node and then creates new equivalence links to the upstream BOM.
• By creating new parts.
This creates a new downstream part and then creates new equivalent links to the copied upstream part. If the copied part is an assembly of parts, no children are created.
• By pasting copied upstream parts to the downstream structure.
When pasting parts the newly created downstream part is pasted as is, with the exact same attributes as the copied part.
• By creating new downstream branch variants.
The resulting new downstream part iteration does not share a part master with the selected upstream part iteration and is launched as the root node of the downstream tree. Additionally, all of the usages from the selected downstream iteration are duplicated on the newly created downstream iteration. The duplication only occurs if a downstream iteration is created. If an existing downstream iteration is used no duplication occurs.
• By creating new downstream part variants.
The resulting new downstream part iteration does not share a part master with the selected upstream part iteration and is launched as the root node of the downstream tree. Additionally, all of the usages from the selected downstream iteration are duplicated on the newly created downstream iteration. The duplication only occurs if a downstream iteration is created. If an existing downstream iteration is used no duplication occurs.

|
The difference between creating a new downstream branch variant and creating new downstream part variant is that the New Downstream Branch Variant action creates a new iteration of an existing master whereas the New Downstream Part Variant action create a new master with an iteration. If a transformation occurs when creating a new downstream branch variant the selected upstream part iteration and the new downstream part iteration share the same part master. When the new downstream part variant is created the selected upstream part iteration and the new downstream part iteration do not share the same part master. The equivalent links and the equivalent occurrence links are maintained when the New Downstream Branch Variant and New Downstream Part Variant actions are executed.
|
When adding parts with associative BOM links, you can define the propagation of attributes from the selected upstream object to the downstream location. For example, you can create the new branch or part by using the same attributes of the upstream object.
 |
To paste all parts using the same column attributes (for example, to paste multiple parts using the Add options, or with the same downstream view), click the Edit Column Attribute Values button. Select the name of the column to apply multiple column attributes to, and then the value you would like to apply to those columns. For example, set all parts to an Add Options value of Add New Part. Repeat for all columns that you would like to edit.
To paste only a selected number of parts using the same column attributes, multi-select the parts that you would like to paste using the same column attributes, and click the Edit Column Attribute Values button. Select the Apply to selected rows check box and click OK. Repeat for all columns that you would like to edit.

|
The Paste Special action on the Clipboard is a special transformation action. It validates the copied information on the source or upstream node and then pastes the information on the target node based on the configuration you specify in the automatic BOM transformation template. The action supports copying multiple nodes in the upstream structure and pasting them under a single downstream parent node. It is not available in the Occurrence mode.
|
Structure Transformation Panels
When performing other structure transformation actions, several panels appear in the action window.
The following options appear in the structure transformation panels, depending on the type of transformation being performed.
|
Field
|
Description
|
||
|---|---|---|---|
|
Downstream View
|
Use to select the downstream view to be used in the transformation.
|
||
|
Downstream BOM Type
|
Use to categorize the type of downstream BOM being used, such as Production, Costing or Testing.
|
||
|
Downstream Alternate BOM
|
Use to select an alternate BOM for the transformation.
|
||
|
Number Suffix
|
By default, when creating a new part Windchill automatically generates a new part number using a suffix-based numbering scheme. To change this behavior edit the following preference: > >
If this preference is disabled then you need to manually enter new part values when creating the new part.
|
||
|
Type
|
The type of object being created during the transformation. This could be a part, or another type of manufacturing object, such as a resource.
|
||
|
Number
|
Identification number for the object.
|
||
|
Child Structure Options
|
Options to be used when performing the transformation. For example:
• Do not duplicate
• Duplicate with propagating
• Duplicate without propagating
|
||
|
