You wish to create a customer master record.


Customer master records are used by both the Financial Accounting (FI) component and the Sales and Distribution (SD) component. If your company also uses the SD application component, you can create and maintain customer master records either together or separately as follows:

You need the Sales and Distribution (SD) application component in order to enter data in the sales area. There are three different ways of processing master records since they are often created and maintained by different departments. In some companies, accounting and sales personnel maintain the general area together and their own areas separately. In other companies, customer master records are maintained centrally.


Before creating a customer master record, you have to make certain system settings, or check existing settings, such as the authorizations. For more information about system configuration, see the activities under Preparations for Creating Customer Master Records in the Implementation Guide (IMG) for Accounts Receivable and Accounts Payable.

Before you create a new master record, you need to check whether a master record already exists in the system for that customer. You can either use the systemís search facilities to do so, or you can switch on the automatic duplication check via Customizing (IMG).

For more information about the duplication check, see the Change Message Control for Customer Master Data activity in the IMG for Financial Accounting.


The following section explains how to create a customer master record centrally for both the sales and accounting departments, or just for accounting. Creating a customer master record centrally involves entering data for both accounting and sales in one step. This method is possible only if you have also installed and configured the Sales and Distribution (SD) application component. For more information, see the Sales and Distribution documentation.

If you wish to enter master data for the accounting department only, use the appropriate functions in Financial Accounting (FI).

There are a number of maintenance functions that you can use to maintain the master data. For more information, see Maintenance Functions for Customer Master Data: Overview
