I'm using the process builder for a certain task. Which will check a field of a record,
if it's value is A1, it will create a new record and set it to A2,
if A2 then set it to A3, and if A3 then set it to A1.
A1, A2, A3 are the only values that should be there.
im planning to use this code inside the formula field of the process builder
