Copying by Replace and Merge

Product Managers and System Engineers can use the Replace & Merge action to reduce feature proliferation within a product line by replacing a logical feature in multiple model versions.

During a replace and merge, the active parts under similar logical features are combined into one GBOM Part table/logical feature. The new logical feature then replaces all instances of the two logical features involved in the merge. You cannot replace and merge logical features once they reach the Release state.

Design variants are not programmatically rolled down for children that are added under a leaf-level logical feature. In such cases, design variants are considered to be user-defined conditions and are not altered in the replace and merge process.

If you use replace and merge on a model version that has been added as a logical feature, and that logical feature has a design variant attached, the replace and merge operation fails without an error message.

Note: If you manually add a variant, option group, variant value, or option to a model version and then add it as a design variant to a logical feature, that variant, option group, variant value, or option is retained in the model version context even if the design variant is removed.

Before you begin: View the Logical View page for a model version. See Logical View Tab on the Logical Structures Page.

Working with Logical Features

Select a logical feature that is in the Preliminary or Review state.
Click Replace & Merge .
Search for the logical features to combine with the selected logical feature.
The search results only include logical features that belong to the same product line hierarchy.

Select one or more logical features, then click Submit.

The app opens the GBOM Part Table for the selected logical feature:


Column Name	Description
Part Number	The part number of the part related to the feature.
Group Number	The group number for the duplicate part. If the part is not a duplicate part, this column is blank.
Originating Feature	The name of the feature to which the part is related.
Part Type	The type of part.
Part State	The current state of the part in its lifecycle.

Select any parts you want to remove from the table, then click Remove Parts . These parts are added as inactive parts for the new feature and are moved to the Inactive Parts table.
Click Done.
