    Hi Suresh ,

    The early delta initialization is only useful if we use "direct delta" as an update method

    When you use the "direct delta" update method in the logistics extraction, you do not have to wait for the successful conclusion of all delta Init requests in order to readmit document postings in the OLTP if you are using an early delta initialization.

    When you use the "queued delta" update method, early delta initialization is essentially of no advantage because here, as with conventional initialization procedures, you can readmit document postings after successfully filling the setup tables, provided that you ensure that no data is transferred from the extraction queue to the delta queue, that is, an update collective run is not triggered until all of the delta init requests have been successfully posted.

    Regardless of the initialization procedure or update method selected, it is nevertheless necessary to stop any document postings for the affected application during a recompilation run in the OLTP (filling the setup tables).

    So it seems it is useful when we select direct delta as update method ,And there would be a time gap between Successful setup table initialization and triggering Infopackage with delta initialization.

    Procedure for dong same :

    You can find the option for Early Delta Init in the InfoPackage on the Update tab. Using this option, the source system update can continue and data can be written to the delta queue while the initialization request is being processed.

    Thanks

    hi

    With early delta initialization you can already write the data to the delta queue or to the delta tables in the application while the initialization is requested in the source system.

    This enables you to initialize the init request, without having to stop posting the data in the source system.
