More information
For sync-based workflows, all layers in the web feature layer must either be versioned and contain a Global ID field or be nonversioned, have archiving enabled, and contain a Global ID field. If the layer participates in a relationship class or has attachments, the relationship class or attachments must be related using a Global ID field as the primary key.
