Add a manufacturing-specific part or container
Add a part, assembly, or container to your target bill of materials (BOM) without generating errors when accountability checks automatically compare the source BOM to the target BOM.
Procedure
You can add manufacturing elements such as welds, resources, and containers to the target BOM (typically a manufacturing BOM, or MBOM) because these do not exist in the source BOM (usually an engineering BOM) and thus report no assignment indications. You can also create a manufacturing element from an existing element that duplicates that element but simply reuses, or references, that element.
To hide assignment indications, your administrator must specify a filtering rule in the Advanced Accountability Check dialog box in the Teamcenter Rich Client.
If you have not done so already, search for and open an existing work package and navigate to the BOM Alignment page.
To create a new, unreferenced manufacturing element in an assembly MBOM:
In the MBOM panel, select an assembly, and in the MBOM toolbar, click Add → Add Child .
In the Add dialog box, type a name and optional description for the element and click Add.
The new manufacturing element is created in the MBOM under the same node as assembly you initially selected.To create a new manufacturing element based on a selected element in an assembly BOM:
In the MBOM panel, select the target element, and click Add → Create Based On .
In the Create Based On dialog box, the ID of the selected element is displayed in the ID text box, with a Revision value of A.
To create a new element with just the ID, do not edit the ID text box; to append a name to the same ID, in the Name text box, type the name to be appended to the ID and click Create.
The source element is duplicated in the MBOM under the same node as the source. The new manufacturing element references the same elements with the same IDs and revisions, but does not duplicate any effectivity.Select the new or referenced manufacturing element in the MBOM, and in the MBOM toolbar, click Edit .
(Usage BOMs only) To replace an existing manufacturing element with a newly created element:
In the MBOM panel, select the target element, and click Add → Save As and Replace .
In the Save As and Replace dialog box, the ID of the selected element is displayed in the ID text box, with a Revision value of A.
To create a new element with just the ID, do not edit the ID text box; to append a name to the same ID, in the Name text box, type the name to be appended to the ID and click Save As and Replace.
The source element is duplicated in the MBOM under the same node as the source. If effectivity is specified in an associated manufacturing change notice (MCN) that is set as the active MCN, then changes made in the usage MBOM inherit their effectivity from the MCN. This behavior, which is reflected in Element Effectivities column, is controlled by the preference MEAlignEffectivityBetweenEbomAndMbom.
Results
You can now modify specific properties in the MBOM table columns of your manufacturing element and click Save → Save Edits , and then use the element for manufacturing-specific operations, such as adding fixtures and resources.
