AME setup for payable invoice

Hi everyone,

Hope you're enjoying good health.

I have a scenario where i have to setup invoice approval as follows:

There are around 40 supplier types and these are classified in two types A, B based on approval. What i need is:

1- if invoice has supplier type falling under class A then approver set 1 should approve the invoice.

2- If invoice has supplier type falling under class B then approver set 2 should approve the invoice.

Please elaborate as to how i can setup AME for the above scenario.

Many thanks,
