Create a structure change
In Structure Manager, perform the necessary modifications (additions, deletions, moves, reshapes) by adding and deleting structure lines, then click Save.
Note You must have write access to the assembly. Change management compares the selected solution item with the associated impacted item in the change by displaying two panes. The left pane displays modifications to the solution item assembly, the right pane displays modifications from the impacted item assembly. By default, additions are blue, deletions are red, moves are green, reshapes are light blue, quantity changes are orange, and so forth. Click Icons/Colors Legend to view the currently defined color for each type of comparison. You can select the comparison colors by choosing Edit→Options→Change Management→Bom Tracking and changing the colors. If the change contains more than one impacted item, change management applies the following rules to select the appropriate impacted item:
Procedure Choose the item revision with the same ID as the selected solution item. If there is no item revision with the same ID, or if there are multiple revisions of the item revision, you are prompted to select one from those listed in the Impacted Items folder.
Note If the selected assembly is a new part, or else not a solution item (for example, you are only making structure change modifications, not creating a supersedure), choose No Impacted Item at the prompt. BOM Change objects of the type Add are created for every component. Examples In the example, the left pane displays the additions to Assy100/B, and the right pane displays the deletions from Assy100/A, as shown. Left pane: Additions to Assy100/B Right pane: Deletions from Assy100/A P10 P10 P21 P11 P15 P15 P25 P18 P19 Assy200/A Assy200/A P30 P30 P21 P11 This completes the first stage of making a supersedure—creating structure changes. These same changes can now be viewed from the BOM Changes view in Change Manager by selecting the solution item. The BOM Changes view displays the modifications (adds, cancels, moves, reshapes) with the specified buttons in the Icons/Colors Legend . The convenience of viewing color-coded changes to a structure might be sufficient for your change management requirements and you have no need to create supersedures.
Note When creating structure changes, the only changes processed are additions, deletions, moves, reshapes, and quantity changes. Changes to other component properties, for example, Find No., occurrence notes) are not included. Variant components are treated as any other component.
