After an administrator enables the Advanced BOM feature enabled, NetSuite automatically converts existing BOMs to read-only legacy BOM records. A legacy BOM is a snapshot of an assembly and its components at the time of conversion. The legacy BOM contains a link to the assembly record. Advanced BOM also links existing routings to corresponding legacy BOMs. NetSuite saves a copy of the link between the routing and the assembly in the event Advanced BOM is disabled. If Advanced BOM is disabled, the routing is linked to the assembly record. After Advanced BOM is enabled, the Assembly/Bill of Materials label changes to Assembly on the New Item, Assembly Item, and Saved Search forms. In addition, the Derived from Member Items Cost Estimate Type is no longer available for Assembly Items.
To view a legacy BOM:
1. Go to Lists > Supply Chain > Bill of Materials.
2. Beside the item you want to display, click View. ■ To view Bill of Materials – click the link under the Legacy BOM for Assembly. ■ To view BOM Revision details – on the Revisions subtab, click the revision Name. Legacy BOM records should be used as back up records only.To modify a legacy BOM record, create a copy of the legacy BOM.
