When we create a purchase order if we click the ''view accounting'' in the invoice before posting it shows the same accounts in the ''accounting distribution'' which shows ''Purchase expenditure for product''.But after posting the invoice system shows the right ''cost of purchased materials invoiced''The voucher should be the same before and after posting the invoice which should show the ''cost of purchased materials invoiced''. We cannot create voucher from product receipt also because In turkey customers do not prefer to create voucher from product receipt. We need to see ''cost of purchased materials '' before posting.
