A Supplier approval structure can have one or more levels, with one or more users per level.
If more than one user is added to the same level, any one of the users can approve the supplier.
If more than one level is defined, at least one user on each level must approve the supplier before the supplier becomes active.
Different workflows can be configured for different supplier types.
The user user cannot request approval as the user doing the approving.
When any data is changed on a supplier the supplier's status will automatically move to "Approval Required". The approval workflow will only start when the user Requests Approval by click the Request Approval button at the bottom of the supplier window
