Reconciling EBOM and MBOM in a Multi-Site environment

The determination of equivalence between the engineering bill of materials (EBOM) and the manufacturing bill of materials (MBOM) is based on the in-context ID (IDIC, also referred to as the absolute occurrence ID). When you paste a part from the EBOM to the MBOM, Teamcenter generates an identical, unique absolute occurrence ID for the part on both the EBOM and the MBOM. This mechanism is used when aligning structures to determine whether parts are missing in the source or target structures.

The ID is generated in the context of the top-level item. Even if you do not have write access to the top level of the EBOM, Teamcenter allows this ID to be generated and saved with the top-level item. If you are using Multi-Site and the EBOM is at the remote site, however, this mechanism does not work as Teamcenter must be able to check out the top level to generate the ID. A similar problem arises if you want to assign from an EBOM that exists on a remote site to a local process.

To enable a remote site to use the EBOM-MBOM mechanism in these situations, your administrator can generate in-context IDs on the EBOM that are available when you paste parts to the MBOM.
