versionNumber property
Represents the existing version (freshness) of the promotion, which can be used to preserve the right order when multiple updates are done at the same time.
If set, the insertion is prevented when version number is lower than the
current version number of the existing promotion. Re-insertion (for
example, promotion refresh after 30 days) can be performed with the
current version_number. If the operation is prevented, the aborted
exception will be thrown.
Optional.
