How to configure invoice approval workflow

Hello Team,

How to configure AME Invoice approval workflow.

My requirement.

we have 3 types of suppliers

     a. IT

     b. HR

     c. ADMIN

in each type we have 10 suppliers.

we have 3 type approvers - X,Y,Z

Note:- 1. All "IT" type supplier invoices  should go to "X" approver.

           2. All "HR" type supplier invoices should go to "Y" approver.

           3. All "ADMIN" Type supplier Invoices should go to "Z" approver.

Configured 3 attributes--

Created VENDOR_TYPE value set (DFF enabled in Invoice level)

Value set type is table --> Pick values from supplier level.

@ Jai Soni -- Please review my Attributes and suggest if anything need to be change.
