Update Enum Type column

I have an enum type column months, once a user enters a month and saves, he has an option to edit the records from another view, but the enum type month cannot be edited once posted, it’s greyed out, the editable constraint is marked as yes too.
how to solve the issue as we need to edit the month record from time to time


The behavior you describe is typically because the column is the key column, or is used to generate the key column value. The key column value cannot change once the row is saved the first time, so any value used to construct the key column value also cannot change.
