In the Broadcom Business Services Console (vcf.broadcom.com), a situation may be encountered where the split or merge buttons for licenses are missing or unavailable. This typically occurs when working with licenses that have been shared between tenants.
This is expected behavior. Currently it is only possible to split/merge licenses that have been assigned to the tenant directly. Split/merging licensing that have been shared with the tenant is not possible.
Work with the tenant that is sharing the licensing to split the licenses accordingly before they are shared with the required tenant.
