Previously, when using the

mutation a unique was required. In alignment with , this mutation now supports non-unique values and the restriction has been removed. This is helpful when performing tasks such as order revision for new order items to be added as you can now freely specify a ref number.

field on the  entity. Enabling greater flexibility to set meaningful status information, such as "substituted", "returned", "replaced", or "cancelled".
