    Update methods:

    Delta: In this type of update you only get the modified records from the delta queue.

    Full: This update gets all the historical data like wise from setup tables as of Lo Extraction.

    Initialization: This can be done with a full load with delta for the future loads or no data with delta capability.

    Delta Management for Logistics extraction:

    Direct Delta:

    With this update mode, the extraction data is transferred with each document posting directly into the BW delta queue.

    Queued Delta:

    With this update mode, the extraction data is collected for the affected application instead of being collected in an extraction queue, and can be transferred as usual with the V3 update by means of an updating collective run into the BW delta queue.

    Non-serialized V3 Update:

    With this update mode, the extraction data for the application considered is written as before into the update tables with the help of a V3 update module. They are kept there as long as the data is selected through an updating collective run and are processed.

    However, in contrast to the current default settings (serialized V3 update), the data in the updating collective run are thereby read without regard to sequence from the update tables and are transferred to the BW delta queue.

    The update method “Serialized V3 Update” will no longer be there due to continuous problems.
