Create report using multiple tables

Hello, I have problem and confuse on how to use create report using more than 2 tables. For example, I want to create a listing report of data from ledgertrans where the voucher does not exists in vendTrans, CustTrans and BankAccountTrans table. I try to use notexistjoin but it is not working properly and the date generated is incorrect. It works by joining two tables but how about more tables. What is the problem and the correct way to do this?

Thank you
