In the financial dimensions setup, standard dimensions (i.e. item group) are mostly defined on company level, custom dimensions (value list) are always cross-company. For legal entity override, each single value needs to be marked as suspended. Additional values will be then shared again.

In fact real value tables are rather company-specific and can't be synchronised to that extent.

It was better to have the possibility to chose custom dimensions as either global or company-specific in order to avoid all this value suspending and get a clear separation of what is allowed to post per legal entity.
