HOW POSDM Transaction Extracted to BW

Hello Experts,

I am new with the POSDM. I don't know how the transaction extracted to BW. From tcode /N/POSDW/MON0,is it direct extracted to Tables i.e /POSDW/TLOGF? Because I have an error issue: There are still no BW systems connected to the DataSource / Message no. RSQU010.

What is the flow of Transaction from POSDM and How transaction extracted to BW from different tables of POSDM?

Thank You and God Bless!
