Post out open items with archive number
(available from V7.7.2247)

The "Post out" function has been extended. From now on you are able to enter an archive number for this posting according to the setting of the voucher type. The archive number of the last allocation (if available) or of the open item itself will be suggested.

You find this extension in the software under "Reports => Open items => Screen" with "right mouse button => Post out".
