Limit part to one BOM row (rule)

Before editing a system rule, ensure that no other users are using the system. After editing a system rule, close the PDXpert client and start it again.

Administrators open this using the Tools ➔ System Rules… menu.

Purpose §

Determines whether a part record's BOM list can have more than one row with the same part number.

Description §

Lets 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 part can't be used on more than one row. If a user tries to add a part that exists on the BOM markup, the system blocks the added part and shows an error message.
This setting tests for duplicate parts only as the part is added to the BOM. If existing BOM lists 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 part can be used on more than one row, but duplicates are unusual. When a user tries to add a part that exists on the BOM markup, the system shows an option to cancel or continue.
On one or more rows (no warning) §
Select if a part number can be used on more than one row, and duplicates are common. No warning is shown.

Details §

In almost all industries, the default setting (Within a single row only) is preferred practice. Manufacturing systems typically expect all individual instances of a part number to be consolidated into one row (at one Find). The assembly's total required quantity is not split across several rows.

However, a few specific manufacturing processes may need several rows with the same part number; for example, a wiring harness manufacturer must specify different lengths of the same wire.

Some manufacturing systems may not accept duplicate part numbers within a bill of materials. Before letting duplicates, make sure 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 shown.
