You can change the work process segment data and associations, but if you clear the Set as Master check box for a work process segment that is already being used as a master segment, an error is displayed in the Feedback Zone. To make changes to a master segment, you must first remove it from the associated work definition.
Procedure
In the navigator, click Production.
Select Work Process Segments and then select the resource you want to work with.
Note: All areas that are compatible with the current resource appear. Green icons indicate a compatible view.
In the Displays panel, select an editor.
The editor appears in the workspace, displaying the resource information.
Click the Details tab.
Clear the Set as Master checkbox to remove the master segment designation from the work process segment.
