Answer / ravikumar

A) V1 denotes time-critical updates used for updating the
actual transaction tables.

B) V2 denotes non-time-critical updates used for updating
statistics tables related to the transaction tables.
For instance, after a sales order entry transaction
is completed, the corresponding sales order tables would be
updated in V1 mode, and the corresponding statistics tables
would be updated in V2 mode.

C) V3 update mode(Uses delta queue technology) is similar
to the V2 update mode. The main difference is that V2
updates are always triggered by applications, while V3
updates may be scheduled independently. Many extraction
programs available for mySAP.com applications today use the
delta queue technology to identify deltas.
