External Billing of Service Transactions in SAP ECC

You can use this function if you want to use SAP ERP Central Component (SAP ECC) to perform billing for any of the following service transactions:

Service contract
Service order
Service confirmation

For service transactions containing items that are defined as relevant for external billing, SAP CRM automatically transfers billing-relevant data to SAP ECC. Transfer takes place when a user sets a particular status for the transaction, as described below under “Features”. The data transferred includes the billing date, products to be billed for (services and service parts), business partners, and conditions.

When data is transferred, a debit memo request is automatically created in SAP ECC for each service transaction, in the form of a sales order. The items in this order represent the billing-relevant items in the original service transaction. You can perform billing immediately for these debit memo requests, without additional processing steps.

Prerequisites

Synchronization of master data (SAP CRM and SAP ECC)
- All business partners used in SAP CRM transactions also exist in SAP ECC.
- Service products in SAP CRM exist as materials in SAP ECC.
Synchronization of pricing conditions (SAP CRM and SAP ECC)

Conditions are identical in both systems.
Customizing of service transactions in SAP CRM
You have set the External Billing indicator for the relevant item categories. You do this in Customizing for Customer Relationship Management, by choosing Billing Define Billing Relevance of Item Categories .
Customizing of controlling objects in SAP ECC
You have defined CRM controlling objects to which costs and revenue generated by external billing can be automatically assigned. You do this in Customizing, by choosing Integration with Other SAP Components Customer Relationship Management Settings for Service Processing Controlling Integration .
Customizing of sales orders in SAP ECC
The sales document type and item category of the sales order in SAP ECC are attributed as relevant for billing and not relevant for shipping.

Mapping of transaction data between SAP CRM and SAP ECC

You need to determine the SAP ECC sales order types and item categories that are used to create a sales order for a particular SAP CRM transaction type and item category. Depending on the Plug-In or SAP ECC system that you are using, you perform mapping in different systems and using different techniques, as shown in the following table:

Release	Component	Mapping Definition
SAP R/3 Plug-In 2004_1, Support Package 9 and below	SAP CRM	Business Add-In CRM_EXT_BILLING
SAP R/3 Plug-In 2004_1, Support Package 10	SAP R/3 Plug-In	Customizing: Integration with Other mySAP.com Components Customer Relationship Management Settings for Service Processing Billing Integration Map Transaction Types and Item Categories
SAP ERP 2005	SAP ECC	Customizing: Integration with Other mySAP.com Components Customer Relationship Management Settings for Service Processing Billing Integration Map Transaction Types and Item Categories

The above mapping definitions also determine the order reason and cancellation reason for a service transaction.

Features

External Billing of Service Orders and Service Confirmations

Data is transferred to SAP ECC when an order or confirmation is set to Completed.

You can cancel invalid items by specifying a reason. The cancellation reason is transferred to SAP ECC through item category mapping, and either the relevant debit memo request item is automatically canceled or, if the item has already been billed, a credit memo request is created.

After data transfer, you can cancel or reject transactions in SAP CRM. If it is no longer possible to cancel individual items later on in the process, for example because an invoice has already been created for a debit memo request, you can create a credit memo request in SAP ECC to reverse a debited amount.

External Billing of Service Contracts

Billing request items generated by a billing plan are transferred automatically to SAP ECC. Service contract items that are relevant for billing are transferred when contract data is updated and a contract item is marked as Released.

Note Note

You cannot cancel service contract items once they have been transferred to SAP ECC.

Modification of CRM Service Transaction Data Before Transfer to SAP ECC

You can influence header and item data, such as partners and conditions, before it is transferred to SAP ECC.

To do this, create an implementation of the Business Add-In (BAdI) CRM_EXT_BILLING (Influencing Data from Service Transactions for Billing in SAP ECC). You can find this BAdI in SAP CRM, in Customizing for Customer Relationship Management, under Start of the navigation path Transactions Next navigation step Settings for Service Transactions Business Add-Ins End of the navigation path . For more information, see the documentation for this BAdI.

Modification of Sales Order Data in SAP ECC Before Data Import

You can modify data such as the order reason, billing block, partner, and conditions.

To do this, create an implementation of the BAdI SRV_BILLING_CHANGE. You can find this BAdI in Customizing for your Plug-In or SAP ECC system, by choosing Start of the navigation path Integration with Other SAP Components Next navigation step Customer Relationship Management Settings for Service Processing Billing Integration BAdI: Influencing Data for External Billing of CRM Service Documents End of the navigation path .
