Configuring the Data Flow for Billing Documents

Each billing document requires a reference document (except billing of external transactions). These reference documents can be the following types of documents:

• Sales document
• Outbound delivery
• Billing document

When billing explicitly, you must enter the number of the reference document as the transaction to be billed.

The following table lists the reference document type for each billing document:

You must always refer to an existing document when creating a billing document.

Data will then be copied from the reference document to the billing document.

For delivery-based billing, the quantities to be billed, for example, can be taken from the delivery; the prices, however are taken from the underlying order.

The reference document is displayed as the source at header level in the copying control table.

The following figure outlines an example of the copying control table:

The system administrator can define how data is transferred in the billing process in the copying control table. The system administrator determines controls for the following:

• The header: the target is the billing type and the source is the sales document type.

• The item: the target is the billing type and the source is the sales document type and the item category.

The following controls are found at header level:

• Reference document; the documents that may be used as reference for billing.
• Determination of foreign trade data, allocation numbers, reference numbers, and item numbers.

The following controls are found at item level:

• Billing quantity:

  Which quantity should be invoiced – the order or delivery quantity?

• Pricing and exchange rate:

  Should pricing, for example, be carried out again or should prices from the order be copied over, and at what exchange rate?

• Price source:

  From where should the conditions in the billing document be carried over (for example, copying over shipment costs from the shipment cost document)?

The figure shows an example of copying requirements.

You can specify the requirements for billing a sales document under requirements in copying control.

You can determine copying requirements for the header and for the item.

With the requirements in copying control you can, for example, specify whether the goods issue has to be posted before billing can be carried out.

You can define your own requirements using transaction VOFM.

The following table lists the billing quantity in the various billing documents:

Delivery and order quantities are referenced in billing. You can also take into account the quantity already billed (depending on the area for which the relevant billing type is used). The examples in the table have been defined in the standard version.

The following figure outlines pricing in the billing document:

The following table describes the pricing types that you can set for the items at the time of billing:

The system administrator can assign a pricing type or define new ones for each billing type and item category combination.

The system administrator can also define how the rate is determined.
