Basic Functions 
Supplier Self-Services (SUS) provides several basic functions for processing procurement documents (see below). Where not otherwise specifically stated, these basic functions are available for the full range of procurement documents. For information on document-specific functions, see the descriptions of the individual procurement documents.
Features
Display a document flow list (detailed view) containing all documents connected with a particular procurement document and indicating their statuses. For example, you can determine whether invoices have been created for a purchase order.
Download any type of document in the CSV, or XML formats.
NoteWhen you download documents, ensure that your SUS user and your computer have the same language and country settings. If this is not the case, the time, date, and numbers appear incorrectly.
End of the note.Print documents in the CSV, XML, or PDF formats.
Hold (save) invoices, credit memos, and confirmations locally and then edit them later, before sending them.
Copy an ASN or invoice, and use it respectively as the basis (template) for a new ASN or invoice.
Display a detailed list of all changes (history) concerning an item (purchase order or confirmation). This can, for example, include the type of change, the user who made the change, and the time at which it was made.
Update price data at header and item level in invoices, purchase orders, confirmations, and credit memos, if you have added new items, changed item quantities or tax rates.
Add a new item by entering a line with the corresponding product data or add items directly from the catalog, when you process confirmations or invoices with limit items.
To update price information after you have added items, select Refresh Prices.
