Manage BOMs > Assign parts to the MBOM
Change the quantity of parts
If the quantity property value for a single part in the engineering bill of materials (EBOM) is equal to the sum quantity of multiple parts in the manufacturing bill of materials (MBOM), you can set the EBOM value to appear as equivalent (a full match) in your accountability check results. To allow you to do this, an administrator must select the Consider quality rollup for multiple match check box on the Inclusion Rules tab of the Advanced Accountability Check dialog box in Manufacturing Process Planner and apply the setting to your user profile.
For more information, see Roll up equivalent line quantities in accountability checks in the Manufacturing Process Planner section of the Teamcenter help.
Example
For an airplane assembly in the EBOM, the quantity for a single part is set to 100. In the MBOM, 85 are assigned to one part in the right wing, and another 15 to the fuselage. The quantity property allows the accountability check to appear as a full match in the EBOM part because the different quantities assigned to the different MBOM parts are equal to the EBOM quantity.
Procedure
Open a work package created in Multi-BOM Manager.
In the EBOM, select a part, such as a rivet, with a value in the Quality column.
The selected part shows a full match .
In the MBOM, select one of the parts containing a quantity value and in the MBOM toolbar, click Edit .
Double-click the value on the Quantity column and edit it to 80, and then in the MBOM toolbar, click Save Edits .In the EBOM, the rivet part displays a partial quantity icon to indicate that the EBOM part quantity is greater than the sum of the MBOM part quantities.
Results
If the sum of the MBOM quantity is greater than the EBOM part quantity, the part displays an over assigned icon .
As long as your administrator has set up your advanced accountability check rules correctly, when assigning an EBOM part that contains a quantity value to multiple parts in an MBOM, click Edit in the MBOM toolbar to specify quantities for each MBOM part, and when the EBOM part displays the full match icon , click Save Edits to save the MBOM. You can change your MBOM quantities at any time as long as they add up to the EBOM part quantity value.
