The Center Type in the Role record is not editable (in UI) once you save it. Do you want to change it since you want to use a new center ?
1. Get the ID of the new center.
In the case above, it is CUSTOM10.
2. Edit the Role record and open Web Console (F12 in the keyboard), and type the following code:
nlapiSetFieldValue(‘centertype’,’XXX’)
Replace XXX with the CUSTOM id.
3. Save the record.
