Duplicate Check 

Usage

With the duplicate check, you can determine whether the imported data record already exists in the CRM system as a business partner. After the address data has been imported to master data object 0ELM_GUID_I, the duplicate check can be performed.

Integration

The duplicate check for external lists from the BI system is performed in SAP CRM.

Prerequisites

To be able to perform the duplicate check, you must have made the necessary Customizing settings in the IMG of the BI system under SAP NetWeaver ® SAP Business Information Warehouse ® General BI Settings ® Customer Relationship Management ® Marketing ® External List Management ® Define Processing for Steps.

Features

In the SAP standard, the duplicate check is performed in an SAP CRM system.

The address list data is read from master data object 0ELM_GUID_I and is transferred by remote function call (RFC) to function module CRM_MKTLIST_DUP_CHECK_RFC in the SAP CRM system.

This function module checks the transferred data using API ADDR_DUPLICATE_CHECK_FOR_BAPI, provided by SAP Business Address Services. In this API, the data is checked using third-party software.

For more information on using the third-party software, see Customizing in the CRM system.

If you are not using an SAP CRM system to perform a duplicate check, you can use Business Add-In Define Checks (BW_BCT_ELM_CHECK). See Customizing for more information on the BAdI.

Activities

To perform the duplicate check, open an address list using the External List Management interface. Choose Duplicate Check and enter the start date for the background job.

The data records identified as duplicates are marked in the master data object 0ELM_GUID_I. Value 1 is entered in attribute 0ELM_DUPLIC for this.

The duplicate check can be repeated.
