Prevent column edit if specific value is already set

[Nin_o]

Hi,

Is it possible to prevent a column from being edited if a certain value is already selected from a list? For example, if the column value is already set to “Option4” then it is no longer editable. If value is either “Option1”,Option2 or Option3, column can still be edited.

Thanks

Please explore Editable_if column constraint on the said column.

Conditionally allow the user to edit a column value.
