Is there a way to shown error message when record saved

I have add the validation logic to entity's formula (Administration » Entity Manager >> Entity Formula), is there anyway to shown the error message on screen if the validation fails? thanks.

Hi,
There is no such an ability to do it with Formula. But you can:
Create a custom field - https://github.com/espocrm/documenta...-field-type.md
OR
Customize existing field - https://github.com/espocrm/documenta...dard-fields.md.

Thank you.
