We run 23R2, Build 23.209.0023. When attempting to use the Finish action via the ConfigurationEntry endpoint, the Supplemental Item does not appear on the Sales Order. This is not the same behavior we see when manually creating an SO, where after closing a Finished Configuration, the SO is updated to include the Supplemental Item.
Has anyone else had success with the Finish action that’s part of the ConfigurationEntry endpoint? It is properly updating the Configured Item’s Line Description.
