Scheduling BO Webi Reports Through Unix Server

Hi,

We have developed Some BO reports in Webi and our requirements is as follows

1)ETL File will be generated and sent to BO server through autosys and once BO server receives that ETL file then BO reports are scehduled on Event based and triggered automatically.(If any failure in report scheduling need to be logged)
2) These reports should be put in Unix server
3)From unix server using SFTP needs to be transfered to the Remote end.

Can anyone tell me how we can do the above Actions

1)How Unix server can get those Bo reports and those Bo reports if failed to generate needs to be logged and successfull generated reports need to be SFTP-d to remote end

Pls Guide me on this

Many Thanks
