Table Join BSIS and VBFA

Hi Experts,

I am trying to join VBFA, BSIS

What i am trying to do is get the revenue and cost accounts and amounts associated with the SD Billing documents. My understanding is that table BSIS provides the financial account data, while table VBFA provides the document flow.

Thus, im trying to get the billing document associated with both the acounting document and delivery documents so that i can pull the revenue and cost accounts associated with the billing documents.

Also, is there a report of function such as "WB2_V_....." that can provide me with the data?  If not can anyone provide help with how to go about it...i can use SE16N?

THank you very much for helping?

Thank you,

Regards,

Victor
