Hi Kran,
Un-searlized V3 update is opted when serialization is not important during the update in BW. In most of the cases, seriailization is critical hence you can use the update method 'Queued delta' for collecting the changes.
You can schedule the V3 job which moves the data from LBWQ Transaction to RSA7 (BW Delta queue) in LBWE Transaction just by clicking 'Job control' button exist at the 'Application level'.
please find the link
Thanks,
Phani.
