Accounts receivable, contract account management, or mass accounting - the SAP component FI-CAX (Contract Accounting Cross Industries) has several translation variants. What they all have in common is the focus on efficient, as automated as possible management of contract and customer processes wherever millions of payments and reminders occur. Thus, FI-CAX is the SAP solution for accounts receivable in industries such as energy, telecommunications, the public sector, or mail order. This book is aimed at both beginners and users who have been working with FI-CAX for some time. The authors have incorporated their extensive practical know-how gained from years of consulting in the field of SAP financial processes into this book. In the second edition, they address current and potential changes arising from the introduction.
