INVOICE APPROVAL RULE BASED ON CONDITIONS

Hi Experts,

We have requirement to create Invoice approval rule based on below condition. Please help us with the IF and THEN condition to be used.

If 3WAY match and if not prepayment and PO amount less than or equal to Inv amount then Autoapprove

If Inv amount greater than the PO it needs to go the Requester only 

If any frieght it should be autoapprove 

If Invoice type Prepayment have to go requester approval only 

Thanks,

Bhushan
