Part 1 in this series lists down various tools and techniques available for MDG data migration.

Part 2 explains the MDG Data Import Framework and File upload method

Part 3 provides details about SAP Data Services and S/4HANA Migration cockpit in terms of MDG data loads

Part 4 explores how next-generation HANA powered tools such as Smart Data Integrator (SDI), Smart Data Quality (SDQ) and SAP Agile Data Preparation (ADP) help in MDG on S/4HANA data migration.

This blog discusses MDG consolidation data import and how traditional data load techniques such as direct input methods and enterprise services can be leveraged for data load in SAP MDG.

Master Data consolidation data import

SAP MDG, consolidation and mass processing allow you to consolidate the master data and assists you to run mass processes to update multiple master data records at a time.

 Data Import Fiori Application

Though the above process flow diagram shows only data import from file, you can leverage other SAP solutions such as SLT and ETL tools to load the data directly into MDG consolidation source tables.

MDG consolidation tables follow <table>_src as naming convention.

BP table names: BUT000_SRC, BUT020_SRC, BUT_ADRC_SRC, KNA1_SRC, LFA1_SRC

Material master table names: MARA_SRC, MARC_SRC, MVKE_SRC

Report MDC_BP_TRANSFORM_SOURCE_DATA can be used for transforming the customer or vendor data to the business partner data model after the source tables are populated.

To load data directly into source tables, refer to SAP note: 2233142 - Example: How to fill Source Tables

Back-end Functions Direct Input/ALE

You can use the traditional data load methods such as Direct input using BAPI, LSMW or ALE to directly load the data into the active area. Ensure that desired data quality is met before using these methods to transfer the data from the old system to the MDG system. Also, note that though LSMW is available but is not considered strategic in SAP S/4HANA.

Refer to following SAP notes when you use LSMW for initial data loads in S/4HANA.

  1. 2287723 - LSMW in SAP S/4HANA on-premise

  2. 2538170 - Migration of Retail Objects to SAP S/4HANA on-premise

Enterprise Services

Though the SOA services generally used in data replication from MDG to external systems, they can be used for data import in MDG.

If your source system (both SAP and non-SAP) can create SOA messages, you can send the master data to be created in the MDG system using the following services.

  • MaterialERPBulkReplicateRequest

  • BusinessPartnerERPBulkReplicateRequest

Using these services, the master data can be created in the inactive area or staging area so it can be following through the governance process.

Tool comparison

By now you’ve learned about quite a number of tools and techniques to consider for the MDG data migration. As I stated earlier, different factors need to be considered while selecting the migration tools and techniques. While there is no comprehensive answer to which tool is good for (your) MDG data migration, my personal preference is SAP Data Services as it pretty much covers all the MDG data migration scenarios.

I hope you find this series of blogs helpful. Please leave a comment on your experience on these tools or anything that I might have missed.
