Costsplit within the edit screen is possible
(available from V6.4.842)

Payments -> Bank Statements -> Edit

From now on you have the possibility to split costs on more than one cost centres/cost units during the edit process directly.
(same functionality like within posting online screen)

Click on the menu item "Edit -> Cost-split" or use the shortcut "CTRL + E".

- You have to enter a real account
- The entered real account needs an allowance for cost centres/cost units
