Maximizing Sap Erp Financials Accounts Payable

This book is a must for any FI or MM consultants who want to take up a new assignment as an AP consultant. I have done one AP implementation before and this book has cleared some of the doubts that i had.This book is much better and covered more information than the "Invoice Verification for SAP R/3" by Stephen Birchall.However there is no information regarding posting incoming invoices through EDI. I was expecting some information on EDI invoices especially with the difficulty in settling planned delivery costs through EDI.Overall, i liked this book.
