LO extraction basics

Hi geeks,

I am making my understanding of LO extractions in BW clear.

say we are talking about sales order item (2LIS_11_VAITM) data.

we have loaded historical data using set-up tables for sales order item data.

Now

i> Sales order item data is changed using VA02

ii> I can see these changed sales order item data into

extraction tables (which we can see in lbwq)

iii>I schedule a job to get this data into BW extraction queue (which I can see in RSA7)...job is scheduled in lbwe lo cockpit

iv> I can load data from RSA7 into BW using info-package.

Please fill any gaps in my understanding about LO extractions.

Any help will be rewarded

Thanx in advance.
