Process tree

After you import the files for a new assembly using the New Assembly wizard, the Process tree in the Process Definition window displays all the components that make up a process definition—including the BOM—as shown in the following illustration.

 

Note

If you aren't viewing a BOM directly after importing the files for an assembly using the New Assembly wizard, you can open the BOM for editing by logging into NPI, double-clicking the assembly to open it in the Process Definition window, then double-clicking the BOM in the Process tree.

Resolve BOM errors

After you import a BOM, there may be errors you need to address such as missing part numbers or documents or other changes. You can make all these changes in the Process Definition window or fix errors from within the imported BOM itself. For example, if there is an incorrect quantity, instead of using the Process Definition window, you can just change it in the BOM listing.

  1. In the Process Definition window, double-click a BOM error to see a dialog with details about the error.

    In this example, Internal Part Numbers are missing from the BOM.

  2.  Use the dialog options to correct the error (in this example, locate the appropriate IPN), then select Save to update the BOM with the correct IPN.

     

Note

For some errors, you have the option to select Ignore next to Actions, then the error entry will remain in Ignore status.

BOM Error List toolbar

The BOM Error List toolbar has useful tools to help you resolve BOM errors after importing.

Launch Wizard 

Launch Wizard button  Launches the Load Design Files wizard where you can replace the current BOM file with a different file.

Add

 

Adds a new part, existing part, or assembly to the BOM for a process definition.

  • Add New Part - Adds a new Internal Part Number to the BOM.

  • Add Existing Part - Adds an existing part number to the BOM.

  • Add Assembly - Adds a new assembly to the BOM.

 

 

Delete 

Delete button  Deletes selected line items from the BOM.

Change Part Type

 

Changes the selected part to a different type: Generic, Electronic, Consumable, or Tooling.

 

 

Mark As Assembly 

Mark As Assembly button  Changes a selected part to an assembly.

Configuration Options

  • Split Item - Splits a selected BOM line item into two additional items.

  • Group Items - Reconfigures selected BOM items into groups.

  • Add to Group - Adds a selected BOM line item to a group.

  • Ungroup Items - Ungroups grouped BOM items.

  • Copy Existing Variant - Copies a selected variant from one assembly to another.


AML/AVL/Alt IPN Options

Specifies approved manufacturer or vendor lists for parts and Alternate IPNs for selected parts.

  • Add/Delete Approved Manufacturer List (AML)

  • Add/Delete Approved Vendor List (AVL)

  • Add/Delete Alternate Internal Part Number (IPN)


Revision Options

Assigns the selected option to the Revision Mode column for all BOM items.

  • Use Latest For All - Uses the latest part revision.

  • Use Any For All - Uses any part revision.

  • Use Specific For All - Uses the specified part revision.

     

Auto-Validation

When selected, error checks you previously set up in NPI Global Options are validated automatically.

Validate

When selected, validates error checks you previously set up in NPI Global Options.

Genealogy

Genealogy button  Displays every line item/component for an assembly and associated details including IPNs, part types, quantities, revision mode, and references (if defined).

 

 

Export BOM

Export BOM button  Exports the BOM to a file and includes only the BOM items you select in the Export BOM dialog.

 

Save and publish a BOM

After you format a BOM, select the Save and Check In Save and Check In button button (the padlock) next to the BOM node of the Process tree on the left side of the window to save and publish the BOM.

 

 



Publishing commits any part linkage (internal to customer and internal to manufacturer) and adds new parts to the global part library. FactoryLogix will then switch to the ECAD node of the tree and present the PCB to you. You can compare the CAD to the BOM for further error-checking by clicking the CAD to BOM Comparison button on the toolbar. The tool will display a list of discrepancies between the CAD and BOM such as reference designators present in the CAD with no matching part numbers in the BOM and vice versa.

  • If you're satisfied with the BOM, select the Save button next to the BOM in the Process tree to save and publish the BOM.
