Why is max_length not working?

[ServiceNow Use6]

Hi,

I have created max_length attibute to Description 5 on incident table, but it is not working. I don't want to use scripting, but why is it not working. Kindly help.

Regards

Hi @ServiceNow Use6 

May you try configure the max length in form builder options

Dictionary override does not allow to change the length of child table [incident] and if it needs to be changed, it should be at parent table [task]. Alternate way is to create Client Script, refer below

@ServiceNow Use6 This is a common confusion in ServiceNow, and here’s why your approach isn’t working as expected:

• The max_length attribute in the Dictionary Override is not enforced at the client-side/UI level. It’s a back-end constraint, meaning it prevents saving a string longer than the limit only at the database level, not in the form input field.

• You can still type more than 5 characters into the field in the UI. The enforcement will only happen when the record is submitted — and even then, it might not trigger a clear validation error unless you specifically script it (which you said you want to avoid).
