How to Setup DFF Multi-level Dependency for Value Sets Up to Three Levels

Summary:

Hi,

We have a requirement for Expense Item screen wherein client wants to see multiple dependent value set for DFFs.

E.g. Level 1 is independent, Level 2 values depend on selection of Level 1, Level 3 values depend on selection of Level 2.

I have found a document but I see there is a step where EFF setup is needed and for which, upon checking, no EFF is available for Expenses Module.
Document Reference: Fusion PIM: How To Setup Dependent EFF Attributes/Value Sets Three Level Or More (Doc ID 2921826.1)

Please let us know how to achieve this requirement. Level 3 values are more than 100 values and we do not want the employee to see everything so it needs to be dependent on Level 2 (which is dependent on Level 1)
