When you work with resource-related billing, you will need to change some of the system settings in the online Implementation Guide. The most important system settings are as follows:

• Settings for document types in SD
• Settings for pricing
• Determining activities for billing request items
• Defining reasons for rejection

For further information, see the online Information Guide.

We recommend that you make the following changes in the document types for sales orders and billing requests:

• To be able to create a billing request for a sales order you need to specify the document type for the subsequent billing request in the settings for the sales order document type.
• You need to specify a condition type in the settings for the billing request document type. The item line values (costs) based on billing are set in the condition type. The condition type must be type Q. The standard proposal is EK01.

During resource-related billing the customer is charged for costs such as bills from vendors, hotel costs etc. In these cases, no general sales price can be specified for the materials that these items represent in the billing request. More often, the price can only be determined from costs in question.

For this reason, conditions for these kinds of prices (e.g. PR00) cannot be marked as mandatory in pricing procedure used for pricing in the billing request.

In resource-related billing, information on the resources required is used when the system creates items in the billing request. The resource items are represented in the billing request as activities. For this reason, you need to assign the following to the activities in the appropriate application (internal orders, maintenance, project system).

• cost elements
• cost center/activity type combinations
• statistical key figures

This is carried out in Customizing.

Internal company services and costs are represented as activities in the standard system. You need to create service materials for these activities so that resource-related billing can take them into account.

Reasons for rejection are used during resource-related billing to:

• Mark items in the billing request as not relevant for billing
• Reset items in the billing request to be dealt with in subsequent billing requests
• Cancel items in a billing request if you want to mark the billing request as canceled.

You can enter a description in the online Implementation Guide for individual reasons for rejection. For each reason for rejection the system also specifies how an item marked with that particular reason for rejection is treated when subsequent new billing requests are created.

For example, the following reasons for rejection could be specified:
