SAP S/4HANA Master Data Transfer to Decentral System with IDoc

In SAP, it is necessary to transfer master data such as supplier, material, customer or invoice information between decentral systems. For example, if you are using an EWM module and a TM module has been added to the company recently, this type of master data information is required for the system to work. To give an example of the opposite situation, when you create an inbound delivery based on the purchase order on the ERP side, the ERP delivery is not transferred to the EWM side or TM side, since the material master data is not defined on the EWM/TM side. Therefore, you can not take any action on the EWM/TM side. In order to avoid such problems, we will examine the subject of IDoc in this article, which is one of the master data transport methods.

Customizing Need to be Checked / Otherwise to be Completed Before Idoc Transfers

1- Activate Change Pointers for Message Type

This must be done on both the target and source systems. Activating the message types allows data that can and cannot be moved. For example; The MATMAS controls material master data, the CREMAS controls vendor master data. This customizing can be done with the transaction code BD50.

2- Logical System Partner Profile Customising

Message type customising should be made to the Logical System (LS) partner profile with the WE20 transaction code. In the Inbound Section customisings should be completed in target system and in the Outboun Section customisings should be completed in source system. They should be selected on the left side of the screen. And also it is important that target or source system needs to be log in while transfering decentral system transfer.

3- DRF Customising

In the DRF customizing, Logical Systems and their RFC destinations have to be defined with the transaction code DRFIMG. Otherwise, systems can not send and receive Idoc messages and get dump error. Both od target and source systems must exist in in the target and source system section. After that Define Bus. Systems, Bos needs to be customized according to the message type. For example for the customer and vendor master data 159-Customer and 266-Supplier have to be defined. Also Define Bus. Systems, BOs, Communication channels have to contain an entry. The entry should be ‘Replication via Idoc ‘, ‘Harmonized IDs (No Key Mapping)’ and other sections ‘Not Defined’. (SAP Note: 2363365)
