Automating Workbench Binding for PartRev Creation

I tried using BPM and Application Studio to set a default value for the ECOGroup, but the data disappears after saving. It seems there might be an issue with the column itself, as setting default values for other columns works successfully. Could you kindly advise if there’s an alternative way to automatically bind a specific workbench when creating a new PartRev? If so, how should it be implemented? Thank you in advance for your help!
