Automatic payment question (F110)

Hi all,

I am trying to see where can I set, if it is settable, that when making an automatic payment the document that closes the vendors open item and is an open item on the outgoing bank sub-account to have the contents of its reference field the same as the document that is being closed/payed. I know that in case of more payments it might me a problem since the system doesn0t know which one to take, but in case of single payment, any ideas if it is possible?

Thanks

Dusko
