Matching Sharing Rules are enabled for the CRM Product object in Vault. They are associated with Lifecycles results in the CRM Vault Metadata Integration. An error in the CRM Vault Metadata Administration tab appears:
[org_url]: Product - Required Vault fields have not been mapped: [lifecycle__v, state__v]; Survey - Upserted: 0, Expired: 0; Directory - Upserted: 0, Expired: 0; Content Type - Upserted: 0, Expired: 0
Matching sharing rules are currently not supported in this configuration. Regardless of whether Matching Sharing Rules are enabled or not, as long as the CRM Product object is associated with a lifecycle, the error would occur when performing the sync action.
