SQVI using FBL5N, VBAK, VBAP & VBRP data

I am trying to build a SQVI report using the FBL5N data (BSID and BSAD tables) and the VBAK table data.  However I cannot find a way to link or join the tables to get the information I need. Eventually I would like the final query to include data from these fields in VBAK, the VBELN, AUART and VGBEL fields along with one custom field. I would like to add this data to  the data in the BSID and BSAD tables to get a "custom" FBL5N.  I have tried getting the data by using the VBAP and VBRP tables but still can't get it to work. Am I missing a table to complete my loop or connections?  Thanks.
