    Hello,

    As we all know ECC version mostly based for Object oriented programming concept,so most of FM are affected by that.

    And most of the Function modules are obsolete in ECC 6 .0 version

    Example :WS_upload or WS_download are obsolete in ECC 6.0

    So we need replace it with GUI_Upload or GUI_download.

    As of now you will not face problem but in near future with new releases you may face problem,that is why SAP ask to change according to upgrade.

    Regards,

    Vishal

    Hi Kannan,

    While upgrading from an older version to newer version some function modules become obsolete and the might not be available in ECC6.0.So ,u need to find the exact replacement of the functional module in latest version.

    For example ws_upload and ws_download and ws_filename_get are obsolete in ECC6.0

    They are replaced by gui_upload and gui_download and cl_gui_frontend_services (class).

    U can track the changes of standard functiona modules and function group usding transaction SPAU.

    Apart from that if ur facing any problem with standard SAP objects u can chk SAP notes in Service.sap.com

    But for customer objects we need to check manually for unicode and syntax errors in the upgraded version.

    For finding the list of FMs which are obsolete chk the table RODIR.

    Hope this will help.

    Regards,

    Lakshman.

    As part of Upgrade SAP may discontinue some of the Function module and provide the Enhanced Function modules for the same.

    The program which are using the old function module will stop wokring and you will have to perform programming changes to replace OLD with NEW.

    GUI_DOWNLOAD should be used instead of WS_DOWNLOAD.
