    Hi Mahesh,

    When a transaction is complete, for example: when a sales order is saved, the Dialogue process completes entries in VBHDR, VBMOD and VB DATA. These are the update table.

    VBHDR: It contains the Header information of the request/transaction

    VBMOD: It take cares of module information

    VBDATA: It contains the data which is needed to be transferred to the tables

    VBERROR: It contains information about error if in case some occurs

    In LBWE, the update mode can be seen, most of the times it is Queued Delta, in this mode the data is updated in the Extraction table through V1 update and then collective run is done in the background that transfers the data from extraction queue to Delta Queue (RSA7) from where it is transferred to BW side.
