CO-PA : Help with Record type (transaction KEP1)

Hi Gurus,

I have been assigned the task of displaying the total value of an invoice in transaction KE30 (profitability report) - selected via sales order : as it is now the report only shows the amount that has been invoiced (which is a part - 1/12 to be exact - of the total amount). For this purpose a new record type has been created but not knowing CO-PA that well I cannot see the connection between the record type and the account, where in customizing do I find the link?

Furthermore any ideas on how to proceed after that?
