Hi Team, 

we are working on Automation rule in my project. while applying Automation rule if anyone other than ARC Program Manager/Admin try to change it should revert back to previous value. 

Its not a single field, it is array of fields. on reverting  custom field array of values but its showing some error.. 

can someone suggest regarding this issue. 

Regards,

Dinesh.
