Though the programs RMBWV303,RMBWV311,RMBWV312 and RMBWV313. will do the same as scheduling via LBWE. you want to do 2 things:
1) As Sales Orders, Deliveries and Invoices are created, the LBWQ queues will start to fill up
2) You want to schedule the jobs via LBWE on a periodic basis to fill the RSA7 logs for 11, 12, 13 (depending on which extractors that you currently have activated)
In addition, I am assuming that you already executed the setup tables for the corresponding extractors, etc...
Let me know if you need additional assistance for the LIS extractors.
