New thumbnail display field

Question

I need a thumbnail field that displays the equivalent tiff filesize of a jpg file. I need to verify that the jpg files upsized by lightroom for "longest side" specs meets a minimum uncompress file size. The only way to currently do that (that I know of) is view every file in photoshop.

Hi John,
Yes you are correct. When your field is a  display field & if you dont enter data in it while creating record, MDM will add default value "New Item" in it. (even if you create record from Portal same thing will happen)
If you want to write Not Null validation on this field below is the work around:
Enable the Required property for your field in console.
But Required property in console works only when u write validation in Data manager.
The default REQUIRED_FIELDS validation does not work if your required field is also a Display field
You need to write addition condition along with REQUIRED_FIELDS.
When you try to create record without entering data in display field, MDM will add default value "New Item" if field lengh is equal to or more than 8 ( or "New It" if legth is 6 for example)
So copy the value which you will get in ur display field and use it as shown below:-
REQUIRED_FIELDS AND Name < >"New Item" (Here Name is considered as display field) (REQUIRED_FIELDS you need to type in expression window)
Or if you dont want to enable required property Then just add Name <> "New Item" validation in your existing expression (Here Name is considered as display field)
Thanks,
