1.When printing a Customer Payment using openerp client 6.1. The printout has the tittle Accounting Voucher. I want to rename it to CUSTOMER RECEIPT but i cant seem to find where to rename it. I have renamed using this code:

grep -rl 'Accounting Voucher //opt/openerp/ | xargs sed -i 's/Accounting Voucher/CUSTOMER PAYMENT/g'

But no changes take place: 2. Is it possible to split the columns in Accounting reports to show Payments And Refunds separetly in the Credit Column?
