(1) If the checkbox is not set, only ASM entries using the identical partner channel that the profile uses in the AS2 Response Route can be selected there. If the checkbox is set, then all ASM entries that have a channel of the same type can be selected (i.e. all ASM entries with an AS2 channel).

Since n emails, with one attachment each, are sent in an ASM session with individual processing, the channel can, therefore, change during the session (and thus sender, subject and recipient). Without individual processing, an email can have multiple attachments.
