SAP ECC CRM Interface BADI Implementation

In this Blog you will learn how to implement the BADI PRODUCT_CUSTOMER2 (Customer Implementations for Data Import). This BADI gets triggered at the interface data exchange from ECC to CRM.

Below is the scenario where we change the GTIN number of a product by deriving it from custom logic and use it instead of the one passed from ECC.

BADI method MAP_R3_TO_CRM_MATERIAL  (Mapping of Material Master Data to Generic Set Types)

This method is used to build  custom logic for any data changes during the data exchange.

Method has a deep structure changing parameter CS_PRODUCT_BDOC Changing COMT_PROD_MATERIAL_BDOC it has all the product related data which can be changed.

Step1: Implement the BADI with a ZXYZ name in SE18 Tcode by clicking one the create implementation as given below.

Step2: Double click on the method MAP_R3_TO_CRM_MATERIAL and give your custom code as give below for my scenario.

method IF_EX_PRODUCT_CUSTOMER2~MAP_R3_TO_CRM_MATERIAL.

By following above steps we can implement the BADI to change interface data and learn how to implement deep structure changes as well.
