Data type format validation will prevent users from selecting incompatible data types that lead to solution import failures and issues with apps, flows, and other clients.
Feature details
Until now, it was possible for incompatible formats to be set for data types through XML and solution import. For example, if a user used XML to change the format of a Text data type column to Date, no error would be raised. This change could be packaged in a solution and then deployed without an error, but when the user attempted to use the app or flow, it would fail due to an incompatible type.
This update will validate whether any data type format changes are compatible with the data type being changed. This will occur using API operations and at solution import. If the change isn't compatible, the user will receive an error with details about the table, column, and type that are incorrectly formatted.
