Before the handover from a unitized visual EBOM to an MBOM is complete, you must create a change record and planning scope needs. However, in this scenario we want to split the planning of our major unitized assembly into two separate planning scopes, one for each installation kit. To realize that, we need to create such planning scopes as related planning scopes.
Related Planning Scopes
To distribute responsibilities between different teams and work on large complex assemblies, you can create related planning scopes for the same source structure (EBOM).
For example, the major assembly aircraft wing is divided into planning scopes for planning the skeleton, hydraulics, electronics, flaps, aileron and so on. The multiple related planning scopes created for the major assembly allow you to distribute the work between different teams and ensure single consumption of the source structure’s components across all the related planning scopes: A component consumed in the first related planning scope is not available for consumption in other related planning scopes.
The Related Planning Scope flag can be set when the planning scope is created either with the transaction VMP_MAINTAIN or with the Manage Unassigned EBOM app.

Summary
- Create change records and distinct planning scopes for installation kits before the EBOM to MBOM handover.
- Related planning scopes enable teamwork and ensure components are consumed only once across scopes.
