Managing EBOMs-MBOMs

Save and replace in context

The manufacturing engineer can create a new MBOM substructure from an existing one, while preserving the occurrence information on the line. Typically, this is done to create a new subassembly when it is not possible to revise the existing subassembly, possibly because the existing MBOM is still in use on the shop floor.

This situation arises in the aerospace industry to create a new kit from an existing one. It is also useful when manually creating an MBOM from an EBOM in cases where you do not want to use a different item type for manufacturing parts. Use this menu command on each level in the structure for which you want to create a manufacturing-specific part.

Select the top line of the subassembly and choose File→Save As→Replace Assembly In Context.

Teamcenter creates a copy of the subassembly and propagates existing alignments to the copy. All relationships of the items in the kit are preserved, regardless of GRM rules. Options and variant rules are not carried over from the original line.

If this action is performed in the context of an incremental change, it is recorded.
