The approv Script
As mentioned already, the approv script
(shown in Example 10-20)
is rather small and insignificant. Its purpose is to take

message to the approver, before disconnecting.
The script itself is extremely simple and is not of primary importance.
What is crucial here is the role that Jabber is playing.
The
<message/> element of Jabber’s
protocol is used to span the R/3 world with the IM world, enabling a business process cycle to take place
outside the normal boundaries of R/3 interaction. On a simple ...
