What are the related set ups to be done for AP invoice approval?Can we set the approval hierarchy even for this?

Hi..

   For Approving an invoice in AP we have to raise one invoice for raising an invoice we have some mandatory fields like supplier, supplier number, Payment terms, distribution sets, date, payment method, bank, payment document etc.

After defining all the above we can raise a invoice,  There s no need of defining the approval group it s not a mandatory, 

Firstly we need to raise an Invoice...

To raise an invoice we need to fill the basic information in the Invoice Fom.

Invoice approval can be done hierarchially.This can be done by a Technical Consultant who sets responsibility for approvals only to certain persons.
