The SAP Connector is specifically designed for SAP R/3 and will not work on SAP Business One since the table structure is completely different.
The secret of the SAP Connector Scriptbuilder template is that its loads the data dictionary tables, so that you can use QlikView to navigate the tables and columns. I have never investigated to see if there is something similar in SAP BO, but I have attached the SAP BO SDK Reference Guide (change the file extension to .chm in order to open the file) which describes all the tables and columns in SAP BO. It is about 5 years old, but since SAP has given up hope on growing the SAP BO market that SAP BO is not going to change very much anymore.
The financial tables you can start with are:
OJDT - GL Entry Header
JDT1 - GL Entry Line
OACT - GL Accounts
OITR - GL Reconciliation Header (New in 2007)
ITR1 - GL Reconciliation Line (New in 2007)
With those tables you can go a long way.
