I am looking for a requirement for decommissioning an ECC system , extracting complete data through LT(Landscape transformation) and loading to ILM and archiving. Please suggest SAP best practice for this scenario. Any how to document , step by step process. Don't confuse with SAP SLT replication to HANA, I am not looking for SLT to HANA scenario.

    The usage of SLT replication sever for ILM does require some customizations. The steps followed are something like this:.

    1. Create/Generate shadow tables in SLT with the same structure details as in source system. For example , if you are interested in transferring BKPF, create ZBKPF in SLT with same structure info.

    2. Use the "Deviation table" configuration in the SLT replication customizing transaction to say transfer data from BKPF into ZBKPF.

    3. Trigger data transfer for BKPF.

    Follow the steps for all the tables which you want to transfer data into SLT for decommissioning purpose.

    Next step is to create archive files out of SLT so that you can take them over to ILM Retention warehouse.

    To create archive files in SLT , you can use two tools:.

    1. LEW : which is an ILM tool to create archiving objects and execute them based on Mass transfer id's created through SLT.

    You can find detailed info at : Decommissioning using Legacy Extraction Workbench

    2. CDE: with some tweaks in the CDE ( if you already know this tool ), you can utilize the archiving functionality.

    Once the archive files are created in SLT, its the standard ILM functionality to connect to SLT and take over archive files and store it in ILM Storage.

    If you are decommissioning a system using SLT approach for the first time, I encourage you to reach out to SAP SLO consulting to guide you .

    Thanks and Regards,

    SAP LT is used for transformation/conversion projects and it provides transformation solutions and the solution portfolios.It provides the transformation capabilities for the following scenarios-

    • Leverage, Sell, Buy and Restructure
    • Uniform and Transform data
    • Consolidate and Reduced IT cost
    • Analyses

    You can get more for each of these scenarios at

    Overview of SAP Landscape Transformation - SAP Library

    Whereas you are looking for the solution to decommission an ECC system and loading to ILM and archiving and I think for this the correct solution would be Using ILM Retention Warehouse for System Decommissioning.

    Here is link where you can get more info about it -
