Modification 1
ABAP Messaging Channels
From Release 7.40, SP02, ABAP Messaging Channels (AMC) enable a new type of communication between AS ABAP programs, which goes beyond the limits of an AS Instance.
Modification 2
New Variants of WAIT UNTIL
The new variant WAIT FOR MESSAGING CHANNELS waits for AMC messages in
ABAP Messaging Channels (AMC). A further
new variant, WAIT FOR ASYNCHRONOUS TASKS, waits for the callback routines of an
aRFC and replaces the previous
statement WAIT UNTIL (which now only exists in an obsolete short form).
