2. Tiles: Migration Cockpit

The migration cockpit is a tool in the SAP S4 Hana cloud, it is used to migrate or transfer transactional data, vendor master data, customer master data, asset master data, cost center and profit center master data from the legacy system to the SAP system. Transferring existing or legacy data is generally the first action after the system design/configuration and master data creation.

Search “Migration Cockpit”

Double-click on “Migrate Your Data” [Active Migration Project]

Go to the Create option and click on “Migrate Data Using Staging Tables”

Name: Migration Project – Finance
Select Local SAP S/4 Hana Database Schema
Click on the “Step 2” button

Note: When we create a migration project, then we must specify a location for the staging tables by selecting one of the following options: Local SAP S/4 Hana Database Schema or Remote SAP HANA Database Schema.

If we use the Local SAP S/4 Hana Database Schema, the SAP S/4 Hana migration cockpit will generate the staging tables in the local ABAP schema of the SAP S/4 Hana system. We use this option if we want to use only XML template files to fill the staging tables with data.

If we use the Remote SAP Hana Database Schema, the SAP S/4 HANA migration cockpit will generate the staging tables in the remote SAP Hana Database Schema. For this option, we can use either an ETL tool (SDI, SAP Data Services, ADP, etc.) or fill the data directly on the SAP Hana database.

Search & select the object “FI – G/L account balance and open/line item”

Note: Migration objects are delivered by the SAP and they describe how to migrate data from the source system to the SAP S/4 HANA public cloud. That means these migration objects contain information about which tables are needed for migrating the data.
