Assign and remove source BOM elements in a target BOM

This procedure walks you through the basics of assigning and removing parts from a source BOM, such as an engineering bill of materials (EBOM) or a source usage BOM, and a target BOM, such as a manufacturing bill of materials (MBOM) or target usage BOM, using target BOM toolbar commands. This example demonstrates the effect of overassigning a part from an EBOM to an MBOM and how to correct that error.

Note

When assigning nodes from an EBOM to an MBOM in Manufacturing-BOM Manager, ensure that the Show Assignment State option is not selected to improve the performance. Use Show Assignment State only when you want to check the partial or complete assignment status between the EBOM and MBOM.

Procedure

1. Search for and open a work package with a linked EBOM and MBOM, and then open the BOM Alignment page.

2. In the MBOM, select an element that you want to assign from the EBOM.

3. In the EBOM, select a line without a full match assignment indication icon , and in the MBOM toolbar, click Assign .

   The variant formula of the MBOM element combines the variant formula of the selected element in the EBOM with the variant formula of its aligned design occurrence. A design BOM is a design structure intended to serve as a virtual represention of the product geometry. Example The variant formula of the element Wheel is ModelFamily = Sports in the EBOM. The variant of the corresponding element Wheel in the design BOM is Wheel_Base = Long. When the EBOM element is assigned to MBOM, the corresponding element Wheel in the MBOM has the following variant formula: CopyModelFamily = Sports & Wheel_base = Long

   Once elements are assigned, accountability is calculated automatically. The EBOM line shows a red icon to indicate that the element is over assigned in the MBOM. Assignment status icons help you to locate and correct problem elements in the MBOM. Note You can also assign and remove multiple parts and assemblies.

4. With the assembly still selected in the MBOM, do the following.

   In the MBOM toolbar, click Remove .

   In the confirmation dialog box, click Remove again.

   The additional element is removed from the MBOM structure and the EBOM icon displays a full match . Note You can also remove elements from the EBOM and multiple assigned parts and assemblies.
