Managing EBOMs-MBOMs
Align single EBOM/MBOM lines with different item types
You can align single lines and their properties even if they have different item types.
Example
You can align a line that has a part type with a line that has an item type.
Procedure
If the EBOM and MBOM are not already linked, link them using the Link Associate→Link Structures command.
(Optional) If you are viewing unconfigured structures, turn them off so that you have 100% BOMs by deselecting the Show Unconfigured toggles.
Run an advanced accountability check, and from the EBOM and MBOM views, select the two lines to be realigned.
Choose Tools→Manufacturing Alignment→Align.
In the Align dialog box, the selected MBOM line is displayed in the Line to be aligned text box and the EBOM line is displayed in the Line to align with text box.
Select Align the selected lines only.
To align all properties in the MEAlignedPropertiesList site preference, select the Align properties (for non-reused assembly lines) check box.
Click Align.
In the prompt warning you that the two lines have different item types, click Yes.
In the Alignment Succeeded prompt, click OK.
Run an accountability check to verify that the structures are aligned.
