  • What causes this issue?

    You want to use change number &V1& to change a BOM or to create a
    variant for an existing BOM. However, this change number does not allow
    changes to BOMs.
    One of the following situations triggered this error message:
    In the change master, the corresponding object type (eg. BOM,
    routing/plan) is not active, so it is not possible to create or change
    objects with this object type using this change number.
    The corresponding object type is currently locked for the creation of
    new data or changes.
    Change number &V1& is the number of an ECR. In this case, an object
    management record is required for the BOM. However, no object management
    records exist for the selected ECR.

    How to fix this error?

    Check your entries.
    If you really want to create your variant or make your changes using
    this change number, consult your system manager responsible for change
    master records to get the change number adapted to suit.
