Self-Billing Document 
Self-Billing Document
Definition
Billing document prepared and sent in by the customer.
In both the standard self-billing procedure and self-billing with invoice creation, the customer sends in a document that is either compared to an existing internal invoice or used as an original invoice for the transaction. The customer sends in correction documents to correct quantities billed in the invoice, or retro-billing documents to adjust prices in the invoice.
Use
The customer can create the following billing documents:
Standard self-billing
The credit advice sent in by the customer is converted to an IDoc and compared to the invoice that you have already created in the R/3 System. This is to ensure that there are no differences between how the customer thinks a transaction should be billed, and how you think it should be billed.
The customer sends in a credit memo request when you have billed a larger quantity of material in the invoice than what was actually delivered. If the credit memo request corresponds to data in the R/3 System, the system creates a credit memo request and then the corresponding credit memo.
The customer sends in a credit or debit memo request to balance out retroactive price adjustments.
The system recognizes what type of self-billing document is sent by the customer from a status set in the intermediate document:
0 = credit advice
1 = credit or debit memo request
The system determines whether the document is a credit or debit memo request by determining whether it has a negative value (credit), or positive value (debit).
Self-billing with invoice creation
The system does not allow you to create an invoice for a delivery to the customer. Rather, the customer sends in an invoice which is converted to an IDoc and actually created in the R/3 System as the customer has prepared it.
Keep the following in mind when handling these invoices:
The customer sends in a credit memo when they have billed a larger quantity of material in the invoice than what was actually delivered. The customer must submit credit memos of this type with reference to the invoice.
The customer sends in a credit or debit memo to balance out retroactive price adjustments. The customer must submit credit and debit memos of this type with reference to one or more invoices.
The customer sends in a cancellation document to cancel existing invoices, credit memos, or debit memos. The customer must submit documents of this type with reference to the document they wish to cancel.
The system recognizes what type of self-billing document is sent by the customer from a status set in the intermediate document:
0 = invoice
1 = credit memo for retro-billing
2 = debit memo for retro-billing
3 = cancellation document
4 = credit memo for quantity corrections
