When creating a view to export, update and reimport data in bulk, if the imported data has more characters than the field, D365 is increasing the max characters value to accommodate the extra fields.
Example is UK postcode. Expecting max 8 characters. On the update, a space was included in front of postcode, total characters = 9.
Expected behaviour was to fail that update for the field, however it imported it and change max from 8 to 9.
Is there a way to enforce it failing?
