Configuration 

To use billing between company codes, make the following settings:

...

       1.      Create an internal customer (transaction XD01)in the supplying company code to represent the requesting company code.

       2.      Assign any sales organization of the requesting company code to the internal customer. In Customizing for Sales and Distribution, choose Billing ® Intercompany Billing ® Define Internal Sales Number by Sales Organization.

We recommend that you assign the internal customer to exactly one sales organization of the company code. Nevertheless, the internal customer represents the entire requesting company code.

       3.      Set up material determination and pricing in the supplying company code as you require for billing from the supplying to the requesting company code.

       4.      Set up a dynamic item process profile (DIP profile) with the new source Intercompany – Line Items. In Customizing for Sales and Distribution, choose Sales ® Sales Documents ® Customer Service ® Service Quotation/Resource-Related Billing ® Profiles for Resource-Related Billing/Quotation Creation. For more information, see Resource-Related Billing.

       5.      Create an internal sales order with an item in the supplying company code for each requesting company code, and assign the DIP profile you created above to the item. You can use this internal sales order at any time. Alternatively, you can use contracts (transaction VA41) instead of sales orders (transaction VA01).

Ensure organizationally, that there is only one internal sales order at this point in time between the supplying and requesting company codes.

Carry out the following activities only if you want to send the billing document from the supplying company code to the requesting company code using the SAP Electronic Data Interchange (SAP-EDI) and post it there electronically. 

§         Set up EDI processing. For more information, see SAP Note 31126 or the Implementation Guide (IMG) for Sales and Distribution under Billing ® Intercompany Billing ® Automatic Posting to Vendor Account (SAP-EDI).

§         Make the settings for invoice receipt, if necessary. For more information see the IMG for Financial Accounting under
Accounts Receivable and Accounts Payable ® Business Transactions ® Incoming Invoices/Credit Memos ® EDI.
