I think that in transaction F110 the way how the open items are selected to form one payment is reading the open items (for example from BKPF) simply in order of appearence into the system when they have been posted.
Could anyone confirm me my thought? I have found nothing such as documentation and I'd like to know if this is changeable or this is strictly standard ABAP!!!!
Thank you all for all answers.
