File handling
It is possible to attach and retrieve documents and images to Business Objects through the REST API.
There are two types of file locations:
• regular file locations
• secure file locations
In addition, there are three type of field formats that are relevant here:
• Document field – displays the path and the name of the file
• Secure document field – displays the name of the file
• Image field – shows a preview of the image (jpg, jpeg, png and gif are allowed file types)
In this section, we have a look at the ‘Communication logs’ of ‘Property details’. On the layout, files of all three file types can be added:
 | The secure document location, allowed file types, and maximum upload sizes are configured in System settings > File locations. |
