Work with change notices > Using the Change Summary panel
Verify source and target notices in the Change Summary panel
Use the Change Summary panel to verify and compare elements between a source BOM, such as an engineering bill of materials (EBOM) or usage source BOM, and a target BOM, such as a manufacturing bill of materials (MBOM) or usage target BOM.
Procedure
In a work package associated with one or more change notices, navigate to the BOM Alignment or Manage Plant BOM View page with a Change Summary panel.
Click a tile in the Change Summary panel to review it in the BOM and MBOM and apply changes as applicable.
If the tile is red with a missing in EBOM icon in the upper-left corner and the indicator Removed in the upper-right corner to report that the element was removed from the EBOM:
Click below MBOM Instances to highlight it in the MBOM. Click Remove to take it out of the MBOM.
The tile color changes to green and the MBOM Instances section is removed to report that the problem is resolved.
If the tile is blue with an unassigned in EBOM icon in the upper-left corner and the indicator Added in the upper-right corner to report that the element was added to the EBOM but not yet assigned to the MBOM:
Click below EBOM Instances to highlight it in the EBOM. Assign it to the MBOM.
The tile color changes to green and the EBOM Instances section is removed to report that the element is assigned.
If the tile is orange with a revision change in EBOM icon in the upper-left corner and the indicator Changed in the upper-right corner to report that an occurrence effectivity change was added to the element in the EBOM but not yet updated in the MBOM:
Click below EBOM Instances to highlight it in the EBOM. Click Propagate to apply the change to the MBOM.
The tile color changes to green and the EBOM Instances section is removed to report that the MBOM element is updated.
If the tile is orange with a revision change in EBOM icon in the upper-left corner and the indicator Replaced in the upper-right corner to report that an element in the EBOM has been replaced with a different element but not yet updated in the MBOM:
Click below EBOM Instances to highlight the new part in the EBOM (004836/A;1-LG-000048 in this example), as well as the old part (004673/A;1-LG-000048) in the MBOM. Click Propagate to replace the part in the MBOM.
The tile color changes to green and the EBOM Instances section reports that the EBOM and MBOM elements are aligned. The names in the Elements column of the EBOM and MBOM are appended with the text New.
If the tile is green, no action is required. If you prefer, you can click it to review the element in the EBOM and perform an action, such as assign a part to the MBOM. In this example, the indicator Changed in the upper-right corner reports that the element revision has changed but requires no change because it is unassigned to the MBOM. Note A green tile with the "Part not assigned yet" statement in the EBOM Instances section can also display a change in occurrence effectivity that requires no change because it is unassigned to the MBOM.
