Q:

Document versus Dynamic Document Property

What is the key difference between Document and Dynamic Document Property?
We were trying to use these properties in Boomi atomsphere process development but not able to decide which is the best to use.

A:

Document Properties: Document properties are additional information or "metadata" about an individual document as it executes through a process. 
Usage: I have used document properties of Disk, FTP, SFTP for creating file names. Also document properties of Mail can be used to create Body, filename, subject, from Address and To Address.
Dynamic Document Properties: Dynamic document properties are properties that the process developer can define and use to temporarily store additional pieces of information about a given document.
Usage: I have used this to create an ALL_INDEX to get all the data from data cache
