Change Billing Documents
Application component: Billing
App type: SAP GUI
Description:  App ID: VF02 With this app, you can change some attributes of billing documents such as invoices, credit memos, and so on. 
Key features:    Change billing document details such as the billing date, texts, pricing, and output items Note Depending on the timing, you can make only limited changes. Before the system has forwarded the billing document to financial accounting, you can do the following:  Change the billing date (in the header details), texts, and output items. This includes the option to trigger a redetermination of output items, which adds the new output items underneath the existing ones.   Carry out new pricing for individual items or change the prices manually  After the system forwards the billing document to financial accounting, you can only change output items and texts. If you need to make other changes, you will have to cancel the billing document and create a new one.   Search for billing documents by document number, company code, fiscal year, or reference   Cancel the billing document that you are currently viewing When you cancel a billing document, the system creates a billing document cancellation (for example, an invoice cancellation), which copies data from the billing document and creates an offsetting entry in financial accounting when it is posted. The cancellation causes the preceding billable document (for example, the delivery) to be open for billing again, so that you can then create the correct billing document.Note   If the system has already posted the now-canceled billing document to financial accounting, it has also automatically posted the corresponding cancellation billing document to offset the canceled document's entry.  If the system has not yet posted the canceled billing document to financial accounting, both the canceled billing document and the cancellation billing document receive posting status E (billing document canceled). In this case, posting is not necessary and no journal entries are created.    Display the document's output items and perform actions such as send, add, and duplicate output, and more. You can also display a PDF preview of the output, which shows what the billing document will look like when it's printed or converted to PDF format. Note The values of some tax fields may not be finalized until the billing document has been posted to financial accounting. Therefore, there are sometimes small numeric discrepancies between tax field values in the output preview (which is generated before posting) and the final output (which is generated after posting). This can be due to financial accounting applying a different currency exchange rate than was used at the time of billing document creation.In some cases, a value may not be calculated at all until the billing document has been posted, and will therefore be missing in the preview.In case of doubt, the values in the final output are correct and the values in the preview should be disregarded.    Navigate to an overview of associated accounting documents   Navigate to the document flow and the pricing conditions for the headerTip The document flow in the Display Billing Documents and Change Billing Documents apps exposes the entire related document chain, independent of business role.In contrast, the process flow in the Manage Billing Documents app and the Billing Document object page offers a simplified representation of the document chain that focuses on documents that are central to the responsibilities of the billing clerk. Therefore, you may see documents in a billing document's document flow that you cannot see in that same billing document's process flow.
