Assign EBOM or manufacturing representation assemblies to an MBOM
You can choose to assign engineering bill of materials (EBOM) or manufacturing representation assemblies, or "mini MBOMs," to manufacturing representation lines in an MBOM.
Prerequisites
Note
To enable this functionality:
The values of the preferences MBMEnableModularMBOM and MbmReleaseStatusForModularBom must be set correctly.
The value of the preference MBMUseEBOMAsIs must be set to true. If MBMUseEBOMAsIs = false, you can only assign manufacturing representations.
Procedure
On the BOM Alignment page, in the EBOM panel, select the manufacturing representation lines that you want to assign, and in the MBOM toolbar, click Assign . Tip The manufacturing representation lines are indicated by Has Manufacturing Representation icons.
The Manufacturing Representations dialog box is displayed, reporting the number of manufacturing representations that exist for the first line in your selection. The name of the selected line is reported at the top of the dialog box. Note When MBMUseEBOMAsIs = false and the selected EBOM node has only one manufacturing representation, the Manufacturing Representation dialog box is not displayed, and the single manufacturing representation is directly assigned to the MBOM.If you selected a single line, select one of the following, and then click Assign.
Select Use existing manufacturing representation to assign the single manufacturing representation.
Select Assign EBOM Assembly to assign the source EBOM assembly.If you selected multiple lines, do the following.
To assign a manufacturing representation that exists for the first EBOM line in your selection, select Use existing manufacturing representation or Assign EBOM Assembly. Note The name of the selected line is reported at the top of the dialog box. If you chose Use existing manufacturing representation, select the preferred manufacturing representation, and click Assign and Next. The name of the second selected line is reported at the top of the dialog box. To assign a manufacturing representation that exists for the second line in your EBOM selection, select Use existing manufacturing representation or Assign EBOM Assembly. If you chose Use existing manufacturing representation, select the preferred manufacturing representation, and click Assign. Repeat this process for any additional lines in your EBOM selection.
Results
The relevant EBOM or manufacturing representation assemblies are assigned to the EBOM.
