Allow duplicate parts on BOM

Before you begin editing a system rule, ensure that no other users are using the system. After you finish editing a system rule, restart your PDXpert client application before working with items.

Purpose

Determines whether a part record's BOM tab will more than one row with the same part number.

Description

Allows multiple rows of the same part number (for example, a wire of various specified lengths) to be added to a BOM list.

Data type

Option selection

Recommended or default value

A part number can be added to a bill of materials

Within a single row only
Default (recommended) setting. Select this if a specific part number can never appear on more than one row. If a user tries to add a part number that already exists on the BOM markup, the system blocks the additional part and displays an error message.
This setting tests for duplicate parts only as the part is added to the BOM. If existing BOM lists already contain duplicate part numbers when you select this system rule setting, the existing assemblies are not changed.
On one or more rows (show warning)
Select this if a specific part number can appear on more than one row, but duplicates are unusual. When a user tries to add a part number that already exists on the BOM markup, the system displays an option to cancel or continue.
On one or more rows (no warning)
Select if a specific part number can appear on more than one row, and duplicates are common. No warning is displayed.

Details

In most industries, the default setting is preferred practice. Manufacturing systems typically expect all individual instances of a part number to be consolidated into a single row, which specifies the total required quantity. However, in limited cases, such as when a wiring harness design specifies different lengths of the same wire, several rows with the same part number can be useful.

Some manufacturing systems may not accept duplicate part numbers within a bill of materials. Before allowing duplicates, verify that downstream software systems can work with multiple rows of the same part number.

When the setting is Within a single row only, then importing a BOM file with duplicates will fail; otherwise, duplicate parts are treated as correct and no warning is displayed.
