As more and more S/4HANA Projects are on the road and customers are planing for a S/4HANA Transformation project in near future I am often asked about “Data Migration”. First of all there is a main difference in the Transformation approach (New Implementation, System Conversion, Selective Data Transition) a customer will choose which leads to the migration approach that matches best. I will not go into detail of each approach but only will highlight my experience with the S/4HANA Migration Cockpit – direct transfer.
You can learn more about the different migration approaches here: https://www.sap.com/documents/2017/07/26113ac0-c47c-0010-82c7-eda71af511fa.html
For a New Implementation customers may choose the S/4HANA Migration Cockpit, as it comes with the S/4 HANA on-Premise Release out of the box without additional costs.
As good starting point I recommend this blog: https://blogs.sap.com/2019/09/23/sap-s4hana-migration-cockpit-tansfer-data-directly-from-sap-system-direct-transfer/
New with S/4HANA 1909 Release is the direct transfer option that allows to migrate data from an existing SAP ERP System (lowest supported release is ERP 6.0 / NW 7.0) directly into S/4HANA via RFC connection. This does neither require staging tables (available since Release 1709 FPS2) nor file transfer (available since Release 1511), which eliminates known data volume restrictions (i.e.100MB file size).
To get MC direct transfer up an running please start with the following SAP notes:
Assign the business roles “SAP_DMIS_OBT_MASTER & SAP_BR_CONFIG_EXPERT_DATA_MIG” to your user. You will find all relevant information about the MC Fiori App here: https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/#/detail/Apps(‘F3473’)/S15OP
Create a new migration project and select the direct transfer scenario.
Next step is to select your migration objects (currently 97). All available Migration objects can be found here (filter by direct transfer!): http://help.sap.com/S4_OP_MO
After you save your project in the background the migration objects are prepared in the system, which takes a couple of minutes. The “Activity Tracking” is a nice function that will show you the status. This can also be used within migration object later on.
Select your data. You can increase the speed by adjusting the background processes.
Under Project settings -> Technical Information you see the maximum available number of background jobs for the whole project.
Then apply your mapping rules. This could be a longer task, depending on the mapping requirements.
Finally you can migrate your data.
Happy data migrating & Best Regards
