LTMC – Legacy Transfer Migration Cockpit
LTMC:
LTMC is a tool used to load data into SAP S/4HANA system. There you can define projects to do the uploading with different options. SAP has created several predefined data migration objects that can be included into the projects.
For data migration objects not yet defined or custom data migration objects, you can use SAP S/4HANA Migration Object Modeler (T.code LTMOM), there you can define (create or modify) objects to use in SAP S/4HANA Migration cockpit.
Data Migration:
Data migration is a process of transforming data from heterogeneous systems to heterogeneous targets with lots of information.
The Data Migration process includes:
Introduction:
In a new implementation of SAP S/4HANA system, data is migrated from the SAP system/Non-SAP system to SAP S/4HANA system.
SAP S/4HANA provides comprehensive migration solutions with no programming requirement by the customer, automated mapping of data between source and target system, predefined templates, easily integrated custom objects, reduce test effort and minimize downtime.
Following are different options available for data migration in SAP S/4HANA on-premises:
SAP Data Services:
SAP DS is an ETL tool from SAP, which was a huge success for Data warehouse and data migration which follows the methodology as E-T-L (Extraction, Transformation, and Load). It also provides data of quality management and text data processing. The ETL capabilities of the tool can be used free of charge, but the data quality features require a Data Services license.
SAP Rapid Data Migration:
The rapid data migration to SAP S/4HANA solution enables you to realize the full benefits of our next-generation business suite even faster. It accelerates the process of cleansing, validating, transforming, and migrating your data from any system to SAP S/4HANA.
SAP S/4HANA Migration Cockpit (MC):
SAP S/4HANA Migration cockpit is an automated migration tool provided with pre-configured content and mapping for each migration object. For all major functional areas like a business partner, product, customer, bank, profit center, cost center, plant, GL, etc.
Migration objects are predefined, and their sequence and dependency are also defined. Each migration object contains its own predefined template in which source data is uploaded. Automatic mapping is done in source and target structures using the template. Migration programs are automatically generated for validating data, simulating data and loading into the target system
Key Features of Migration Cockpit:
In S/4 HANA LTMC is divided in two Parts:
LTMOM:
There are a few customization fields that must be added, where LTMC can’t help then LTMOM has come to the rescue of the situation here.
LTMOM will allow us to create additional fields and customization fields in the source structure and mapped to the target structure.
