Invoicing SD Billing Documents (VBRK) 
Using the invoicing function Invoice SD Billing Documents, you can process documents that Sales and Distribution (SD) creates and then posts in invoicing, or that you want to process into an invoice. The objects involved here are source documents to be invoiced of the source document category SD Billing Document (VBRK). Source documents of the source document category SD Billing Document are special SD billing documents with a billing type that is intended for Invoicing in Contract Accounts Receivable and Payable.
There are invoicing orders for the SD billing document, and the SD billing document is contained in the list of invoicing orders for the contract account to be invoiced.
If the source document category SD Documents (VBRK) is set by the Main Selection indicator, then an SD billing document can trigger invoicing of the related contract account.
When an SD billing document is invoiced, the system adds the billing document to an invoicing unit and generates an invoicing document for each invoicing unit. The system posts the SD billing document in Contract Accounts Receivable and Payable and displays it in the invoice.
The determination and calculation of taxes already took place when the SD billing document was created in Sales and Distribution (SD). So the tax displayed on the invoice, as well as the tax to be posted in FI-CA is already specified.
In the invoicing document, the SD items are designated with invoicing item type 0VBRK_IT. These items are considered in the final invoice amount.
The system manages an invoicing history and reversal history for the SD billing document.
Document Links
Invoicing links the SD billing document with the invoicing document by means of the invoicing history (DFKKINVDOC_S) with source document category SRCDOCCAT = VBRK (SD Billing Document).
The posting documents created during invoicing of the SD billing document are linked with the invoicing document by means of reference table (DFKKINVDOC_P) with reference document type CADOCTYPE = VBRK (Posting Document for SD Billing Document).
Creation of the Posting Document
The posting document is created using the accounting interface.
Creation of Invoicing Items
The system creates the invoicing items in the invoicing document based on the posting document of the SD billing document. An invoicing document item (DFKKINVDOC_I) is created for each business partner item. Along with the amount data, the invoicing document item adopts data such as the company code, account determination ID, and main and subtransaction.
The invoicing items are designated with the invoicing item type ITEMTYPE = 0VBRK_IT (SD Billing Document). These items are relevant for printing, posting, and the final invoice amount. This means that the system considers the amount of the invoicing items in the final invoice amount in the header of the invoicing document.
The invoicing document item also receives a reference to the SD billing document from which it originates. This link is established by means of the fields SRCDOCCAT (Category of Source Document to Be Invoiced VBRK) and SRCDOCNO (Number of Source Document to Be Invoiced).
