    Adding to earlier reply....

    Some points that will add info to you.

    1.Developer need to run the Transaction SPDD which provides the details of SAP Standard Dictionary objects that have been modified by the client. Users need to take a decision to keep the changes or revert back to the SAP Standard Structure. More often decision is to keep the change. This is mandatory activity in upgrade and avoids data loses in new system.

    2. After completing SPDD transaction, we need to run SPAU Transaction to get the list of Standard SAP programs that have been modified. This activity can be done in phases even after the upgrade. Generally this will be done in same go so that your testing results are consistent and have more confident in upgrade.

    3. Run SPUMG Transaction for Unicode Conversion in non-Unicode system. SPUM4 in 4.6c.

    4. Then we need to move Z/Y Objects. Need to do Extended programming check, SQL trace, Unit testing, Integration testing, Final testing, Regression Testing, Acceptance Testing etc.

    SPDD is used to identify dictionary objects


    SPAU (repository objects), will identify any objects where the hot package is overwriting changes you have made through OSS notes.

    You must check all objects identified in SPAU and decide whether you need to reapply the OSS note or reset the code to the original SAP Code.

    When you upgrade the dev environment you may generate a transport in SPDD (at the begin of ACT_* phase) and at the end of upgrade for SPAU.

    You may then include this transport in the next system upgrade (QAS) system, The Upgrade program will ask you this at prepare.

    The procedure is well explained in The SAP on-line help (

    Hope this Helps
