(Salesforce beginner here)
Hi all,
I have a custom object Book with an "author" field that's a Lookup to another custom object Person.
Sometimes the author of a book is unknown and in that case the page layout for such a book shows nothing in the "author" field.
Is it possible to instead show some generic text like "unknown author" when a Book's author field is null?

Thanks,
VR

is there any possibility of uploading a video file or directly a video in salesforce sandbox

 

 

Thanks In advance
