Background documentationSolution: Object-Based Reduction for SAP Retail


This migration solution is applicable to the migration of data from an SAP Retail system.

With this migration solution, you can migrate the following types of data:

  • Transactional Data: You are required to specify the plants or customer numbers and a data slice date. SAP TDMS migrates all transactional data specific to SAP Retail for the specified plants or customer numbers. SAP TDMS transfers all other transactional data based on the data slice date.

    Note Note

    To ensure data consistency in the receiver client for the specified data slice date, SAP TDMS transfers additional transactional data that is business-relevant.

    End of the note.
  • Master Data and Customizing Data: SAP TDMS transfers the complete set of master data and Customizing data regardless of the data slice date you specified.

  • SAP ERP HCM Data: You can choose to migrate SAP ERP HCM data based on the data slice date you specify.


You can carry out data scrambling in the sender system after selecting the data and before transferring the data to the receiver system.

SAP TDMS copies the data selected for transfer for a data cluster and scrambles the cluster data before transfer.


This migration solution includes the following phases:


  • Package Settings

    In this phase, you make certain technical settings such as assigning logical system names in the receiver system, excluding user-related data from data transfer, specifying scrambling rules, selecting additional customer-created tables for transfer and so on.

    In addition, you select the plants and customer numbers relevant for transfer to the receiver system. You also specify the data slice date.

  • System Analysis

    You execute background activities that prepare the migration objects for transfer and generate programs for data deletion.

    You confirm your settings so that they become effective for the data transfer.

  • Data Transfer

    In this phase, you execute TDMS header activities to select business process data. You also execute the final checks before data transfer to ensure that no significant changes have taken place in the repository of the sender system while your SAP TDMS project is running.

    SAP TDMS deletes the existing data from the receiver client and starts the data transfer. You can lock the users in the receiver system so that no changes take place during data deletion and data transfer.

  • Post-Transfer Processing

    In this phase, SAP TDMS makes a few post-transfer settings in the receiver system such as adjustment of number ranges and adjustment of Business Workplace tables.

    If you had set a lock on users in the receiver system during data deletion, you can unlock the users now.

    You can clear the temporary tables filled during the data migration in all participating systems.
