LTMC (Legacy Transfer Migration Cockpit) for customer master data upload process

LTMC

Overview

When we are Implementing SAP S/4HANA solution, we can migrate our master data and business data from SAP systems or non-SAP systems to SAP S/4HANA by using SAP S/4HANA migration cockpit. 

The SAP S/4HANA migration cockpit uses migration objects to identify and transfer the relevant data. A migration object describes how to migrate data for a specific business object to SAP S/4HANA. It contains information about the relevant source and target structures, as well as the relationships between these structures. It also contains mapping information for the relevant fields, as well as any rules used to convert values that are migrated from source fields to target fields. SAP provides predefined migration objects that you can use to transfer your data. 

The Tool used to perform Migration is LTMC – (Legacy Transfer Migration Cockpit). You can access the SAP S/4HANA migration cockpit by using transaction LTMC.    

LTMC is used to migrate data to transfer a mass objects or data’s into a system. The advanced migration cockpit works on S/4HANA. The approach to upload the data can be done in the below ways.

  1. Files Approach – The excel based approach which has pre-defined templates for each of the objects that needs to be filled with the relevant data from the source system/files. For More info on Files approach, click here

  2. Staging Approach – A database connection to the source system database for the relevant objects where the staging tables are created for the data transfer. For more info on staging approach, click here
  3. Direct Transfer from SAP system– An RFC connection-based transfer from the existing ERP system to S/4HANA. For more info on direct transfer from SAP system, click here
