Book Information in DPO
In the P.O. Book Information section, you manage the basic data of your project. This area serves as a central hub for all master data, including book names, invoice addresses, and book limits.
P.O. Book Information
Behind the P.O. Book Information tab in your settings section, you will find three options to manage your P.O. book:
- General P.O. Book Information – Change your book name
- Invoice Address – Enter and manage your invoicing address
- Book Limits – Adjust your storage, user, and P.O. limits
General P.O. Book Information
Here you enter the key data of your project:
Project Name → The official title of your project.
Project Number → A unique number for identification within the system.
Project Duration → The period during which the project is active – with an option for extension.

Invoice Address
Enter the address of the invoice recipient, including:
- Company, Street, ZIP Code, City, and Country
