I’m creating canvas app with CDS data source. There are two entities as “Expense” , and related “Expense Items” with 1:N relationships.
User should fill in fields to describe their expense and each "Expense Items" required to attach Receipt as photo image (.jpg) ,using attachment in Notes.
At gallery control in Canvas app I’ve tried to display attached image file but cannot find field that I should refer.
How can I refer image (files) attached?
