if the alternative scenario (the new created with new altid) record's attribute value is changed in the MIKE+ GUI, a new record of the format "Pipe_muid; Pipe_altid; Pipe_attribute" gets inserted into the "m_ScenarioManagementUpdatedFields" table in the sqlite database representing the current model.
I didn't see this happen if I modified the new pipe record's attribute value using the data_access.set_values() method via mikepluspy module.
