I have found the following on the blog of Plataan:
"However, following circumstances will result into more payment transactions:
•the Payment Journal Line contains a Standard Format Message; per standard format message a new payment transaction will be created (CTRL+F8: Standard Format Message = Yes; Separate Line = Yes)
•the Payment Journal Line contains a partial payment; per partial payment a new payment transaction will be created (CTRL+F8: Partial Payment = Yes; Separate Line = Yes)
•Electronic Banking Setup: Cut off Payment Message Texts is not activated; Normally all Payment Messages of all Payment Journal Lines from one vendor are put together into one payment message for the payment transaction. However this can only contain a certain amount of characters (106 for domestic payments, 140 for international payments). Two or more payment transactions will then be created to make sure all payment messages are taken into account."

I have been testing with the first option (standard message = yes, seperate line = yes). But the payment journal lines are still grouped into one line in the payment file.
Does anyone know if there is sth else I should take into account?
