Import a BOM with unique level numbers that determine the relationships.
Before proceeding with the import, review Import Validation Rules for Item Revisioning Data.
On the Edit Import page, map and configure your BOM import data.
Map the incoming Excel values to the corresponding workspace fields. From the drop-down list above each Excel column, select a workspace field.

Locate the column in the Excel sheet that represents the BOM levels. Click the header for the level column and then select Match as BOM Level key to indicate that this column will be used to determine the BOM structure when it is imported.

Specify which column to use for the comparison:
Pick a column to use for comparison. If it is not yet mapped, map it to a workspace field.
Click the Excel column header and then select Match On. The values in the column will be compared against existing records in the workspace.

You can import classification properties if the selected workspace has classifications enabled and the Excel worksheet includes classification data. One column in the Excel file must contain the system name of the class to which each item belongs. The column must be mapped as the class entry column in the import table. Fusion Manage attempts to map incoming fields to those in Classification Manager.
For BOM parent items

If necessary, edit the project name and description.
In the For new records drop-down list, indicate how to handle new parent items:
Add to the workspace
Append new records to the workspace
Skip
Do not add new records to the workspace
Error
Do not add new records to the workspace and report an error
In the For matching records drop-down list, indicate how to handle updates to existing parent items:
Add to the workspace
Overwrite the existing records in the workspace
Skip
Do not overwrite the existing records in the workspace
Error
Do not overwrite the existing records and report an error
In the For new picklist values drop-down list, indicate how to handle new picklist values:
Add to the existing picklist

Use blank instead
Ignore the new value

For BOM child items
Click the Import Settings tab.

In the For new BOM relationships drop-down list, indicate how to handle new BOM parent-child relationships:
Add to the workspace
Include new relationships with existing relationships in the workspace
Skip
Do not add any new relationships to the workspace
Error
Do not add any new relationships to the workspace and report an error
In the For existing BOM relationships drop-down list, indicate how to handle updates to existing BOM parent-child relationships:
Add to the workspace
Overwrite existing relationships in the workspace
Skip
Do not overwrite existing relationships in the workspace
Error
Do not overwrite existing relationships in the workspace and report an error
Workspace fields can have validations and constraints associated with them to ensure that the proper data types are entered and that required values are supplied. You can choose whether or not to adhere to the existing requirements.
Strictly enforce all validations and constraints
All field validations and required values must be met
Ignore validations and constraints whenever possible
Field validations and required values that can be ignored will be ignored
