we install the MDG 8.0 and active the Material Function. I can create material and generate change request. but in the UI of material creation. some field is not available to input value. they are gray. I find there is a configuration in GENERAL Settings->Processing Modeling->Define Governance Scope. when I set the fields to 'Yes' and save. there is runtime error-> Exception condition "Invalid_FIELDNAME" triggered. all of them are standard field, no any new fields. Could you please suggest how to fix this issue?
