Hi, 

Not that I can see.   Usually, the creation of the payment order creates a payment file.  Given this, if you hypothetically changed a cash account in a screen, that would not then flow back to the file / regen the file.  That payment file could have already been sent to a bank.  So…. no IFS does not have an option where you can simply change the cash account at that stage in the payment process. 

If the Payment order has an issue like selecting bad data / bad cash account, you can alter the payment order - canceling the necessary items from the payment order, or in the case, of a wrong cash account, cancel the entire order, and start over. 

Best regards, 

Thomas
