PO Approval Groups need to be defined when using Employee-Supervisor integrated with AME??

Hi,

The standard Employee-Supervisor funcitonality requires the definition of Approval Groups to setup the approval amount limits and the assignment of this approval groups to the Job assigned to the employee.....

When using AME based in Employee-Supervisor functionality, is it necessary to define the PO Approval Groups and PO Approval Assignments to the jobs or this is NOT required and is replaced with the definition of conditions, rules, etc

Help on this is really appreciated.

Regards,

Veronica
