Identifying assignment statuses of packed EBOM lines

In an engineering bill of materials (EBOM), if you pack a specific structure line or lines, you can view the status of the individual packed lines (occurrences) by pausing your mouse over the EBOM assignment icon. The example below reports that all line occurrences in a packed line with a fully assigned icon are assigned to the manufacturing bill of materials (MBOM).

Partially assigned line occurrences in a packed line are indicated by the partially assigned icon .

If you select a partially assigned line by clicking and choosing Unpack, any line occurrence partially assigned to the MBOM is displayed. In this example, only a single line occurrence is assigned.

To resolve the issue, click the assignment icon in the EBOM to locate the part in the MBOM where all previously packed lines should be assigned. You can then click each unassigned line in the EBOM, and in the MBOM toolbar, click to assign each unassigned occurrence line.

If you repack the assembly in the EBOM, it now displays as fully assigned . If you assign a line occurrence more than once it displays an overassigned icon , and if it is packed again the overassigned icon remains. Unpacking partially or overassigned icons in the EBOM and viewing their assignments in the MBOM lets you better understand the nature of their overall statuses.
