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 data.  However I cannot find a way to line the tables. I would like to add the data from the VBELN, AUART and VGBEL fields, along with a custom field, from the VBAK data to the BSID and BSAD tables. The end result is that I would like the data from FBL5N to include these fields from the VBAK table. Ideally I would like to link, BSID, BSAD and VBAK together.  I feel I may need another table or 2 to complete the circuit, is there a way to do this?  If I can get this link down I can probably add the info from VBAP and VBRP.  Thanks.
