How can I fetch all MM related inv and credit notes from BKPF/BSEG?

Hello experts.

Could someone please help on this?

I did a search but I could not find a confirming answer, though there are a few related threads.

I want to take all MM Documents through BKPF or BSEG table.

My idea was to fetch all docs BKPF-AWTYP or GLWOR = RMRP and pass them to BSEG KTOSL <not equal> Blank.

Or  BSEG table with Trasaction(KTOSL) = WRX.

In this will I get all docs (inv and credits) with PO?

Could you please help urgently?

Thanks in advance!
