As many clients intended to move from Traditional ECC 6 system to S/4 HANA system, there is
always a question about Data Migration of Master and Transactional Data from ECC to S/4HANA
We are know, LSMW a data migration tool is being offered in ECC system by SAP to migrated data from Legacy system to SAP.
There are numerous questions around LSMW, whether we can use LSMW even in S/4HANA ?
1. At first is LSMW offered to S/4HANA customers ?
2. What are the Advantages and Disadvantages of LSMW ?
3. If LSMW is not suitable, what other alternatives available in S4HANA?
Lets check answers for above questions which will give us a great insight on Data Migration in S/4HANA
LSMW- A Legacy system Migration Cockpit which is used in our Tradition ECC system for migration of Data from Legacy to ECC 6. No special introduction is needed to this tool as it is available for use from R/2 Architectures with many new Functionalities added in every stage of Business suite such as R/3, Netweaver ...
This tool is even available in S/4HANA , but with restrictions. What are those Restrictions? Can we get any support if Client is oriented to this tool from SAP
>>> So the answer is, Restrictions are many such as LSMW is used with standard interfaces like
BATCH INPUT
DIRECT INPUT
RECORDING
keeping in view the ECC system and Non-HANA data base.
Also there are many simplifications in terms of certain functionalities such as Business Partner for example cannot be supported in LSMW in any interface of LSMW Tool
SAP recommends not to use LSMW for any data migration and it is Clients discretion if wanted to use so. There would be no support if client runs into issues while using this toolThis triggers question on what are the alternatives to LSMW...,
SAP Recommends
Option 1:--- MIGRATION COCKPIT & MIGRATION OBJECT MODELLER.
We have standard Migration objects available since initial version of S4HANA and by now 1909 almost every object is available for migration ( as far as 1909 - On premise version, there are 280 + objects available )
We can use migration of data using Predefine Templates to generate the data or Staging Tables ( Staging tables are available from 1709 onwards)
We also have another option from 1909 , which is direct transfer of data from ECC as source to S4HANA. Here you need to map your soure and target systems which is more simplified than above two options
Option 2: RAPID DATA MIGRATION
This option is based on Data Services and migration objects are available in this option too . As per recent update, SAP is not going to improve this as there would be more updates henceforth only for Migration Cockpit than RDS.
As this is using Data Services, we need to get separate license to make use of Data services and it is not part of S4HANA license
Option 3: SAP LANDSCAPE TRANSFORMATION
This option is also not available as Inbuilt in S4HANA license, which means a separate license is required for it and license also varies based on the functionality and source and target Architecture
It is widely used for Central Finance Migration.
