Item numbers for parts and subassemblies can be created and maintained automatically in an assembly model. Item numbers are based on the assembly structure, that is, the order in which parts, subassemblies, and assemblies are displayed in Assembly PathFinder.
Once created, you can use assembly item numbers in assembly reports, including pipe and tubing reports produced in XpresRoute, and structural frame design reports. The item numbers are saved with the assembly and are available for downstream use, for example, in PMI balloons placed on the model and in ballooned parts lists on an assembly drawing. This ensures consistent part numbering is propagated across all applications of the model.
You can create item numbers in an assembly model by selecting the Maintain item numbers check box in the Item Numbers page (Solid Edge Options dialog box). As new items are added to the assembly, new item numbers are created. If items are removed from the assembly, their item numbers are not available for reuse.
You can remove item numbers from the assembly by deselecting the Maintain item numbers check box.
Item number creation can be enabled and disabled at any time.
Item numbers can be generated as the assembly is built by enabling item number creation before items are added to the assembly.
In some cases, it may be better to enable item numbers after most of the assembly structure has been created.
You can edit item numbers in the model by selecting the top level assembly occurrence in PathFinder and choosing the Occurrence Properties command. The Item Number column in the Occurrences Properties dialog box shows the assembly item numbers. You can:
Change existing item numbers.
Add missing item numbers using the Next Available Number command on the shortcut menu.
Use the Reset Item Numbers command on the shortcut menu to cancel your edits and restore the item numbers generated by the assembly structure.
You can use the assembly-generated item numbers in assembly reports when you select the Use assembly generated items number check box in the assembly Report dialog box. The item numbers are shown when you select the Format button to open the Format Report dialog box or in the Report Output dialog box.
See the help topic, Create a report.
You can display assembly item numbers in PMI balloons placed on the model.
When you select the PMI tab→Annotation group→Balloon command, you can use these options on the Balloon command bar to retrieve the item numbers from the assembly and display them in the balloon:
Item Number button 
Item Count button 
On an assembly drawing, you can:
Review the assembly generated item numbers on the Item Number page (Parts List Properties dialog box). The numbers shown in the first column correspond to the assembly structure.
Show the assembly generated item numbers in a ballooned parts list by selecting the Use assembly generated items number check box on the Options page (Parts List Properties dialog box).
Use the Item Numbers page (Solid Edge Options dialog box) to select an item numbering schema for the parts and subassemblies in the assembly model. Refer to the following table for a comparison of item numbering options.
Example:
The gray shaded cells below indicate the assembly structure, where A1 and A2 are subassemblies, and P1, P2, P3, P4, and P5 are parts.
The unshaded cells show how flat list item numbering is applied to the assembly structure.
The last column shows the level based item number option, which is available only for Exploded - Top down item numbers.

You can format the item numbers shown in the assembly model by selecting the following options on the Item Numbers page (Solid Edge Options dialog box):

In the Teamcenter-managed environment, the integration of Solid Edge Item Numbers with Teamcenter Find Numbers is governed by the Teamcenter preference SEEC_Synchronize_ItemNumbers. This site preference, delivered by SEEC Administrator, provides a single point for enabling and configuring Item Number options. When you enable SEEC_Synchronize_ItemNumbers the Solid Edge Options, Item Numbers page is available for viewing only. Definitions are based on the values specified by the preference.
By enabling SEEC_Synchronize_ItemNumbers, you can construct a view in Structure Manager that is consistent with a draft's parts list. Synchronization is bi-directional. Existing structures that contain non-modeled items (virtual components) and associated occurrences cannot be reset. The item numbers are locked. However, when an Item Number is assigned either through reset or when placing a new occurrence, the numbers assigned do not conflict with numbers locked by virtual components.
There are a few important governing rules to be aware of:
Item Numbers are supported at the top level only.
Any change to the Item Number options results in a reset.
Item Numbers assigned to non-medeled Item Revisions are considered locked or fixed. These BOM lines are not included in Solid Edge Save.
Solid Edge will not assign an Item Number that is currently assigned to non-modeled Item Revisions.
The reset command will not impact an Item Number that is currently assigned to a non-modeled revision.
Item Numbers must be unique by document reference. If they are not unique, Solid Edge keeps the lowest Item Number and assigns it to all occurrences of that reference.
The Teamcenter Preferences section of the Solid Edge Administrator's Guide provides details regarding preference options.
