What happens when a purchase order is 'flipped' into an invoice?

When a purchase order is 'flipped' into an invoice, all relevant fields in the invoice are filled automatically. This process leverages the existing data from the purchase order, streamlining the invoicing process for suppliers. By automatically populating the invoice fields, it reduces the chances of errors and saves time, as the supplier does not have to enter the same information again manually. This automation also helps in ensuring that the invoice aligns with the original purchase terms, such as items, quantities, and agreed prices, facilitating a smoother reconciliation process when it comes to payment processing.

The other options do not accurately describe the process. For instance, the purchase order is not deleted but rather serves as the foundation for the invoice. Similarly, the supplier does not need to manually enter all invoice information, as the purpose of flipping is to automate this task. Lastly, the purchase order remains valid and is utilized in creating the invoice rather than becoming invalid. Hence, option B is the most accurate representation of this functionality within the SAP Ariba Procurement platform.
