How Reference Numbers Are Generated


Reference Numbers are unique to each object within Workfront. Every time an object is created, the Reference Number is incremented. There can be “jumps" if other projects were entered that the user does not have access to, prior projects were deleted, or personal projects were entered. 
There is a single set of unique reference numbers across all object types and objects are numbered sequentially across item types.
When a user creates a new object, the assigned unique Reference Number will increment from the highest existing Reference Number across all item types. 


Let's assume that the highest Reference Number across all item types is 9,624.
Adding 10 tasks and then 1 project will set the Reference Numbers in the following way:
Object Reference Number
Task 9,625 - 9,634
Project 9,635
