Dear compiere forum members,

to implement an ERP system into the infrastructure of a midsize company
I would like to use compiere but the following functionality is needed:

scenario:
A message is sent to compiere containing a query or an order. This query is
then accepted/rejected by a staff member. Now compiere has to send a message
containing this status change to an external system or somehow trigger
this system to send a status request to compiere.

1) Is compiere able to send messages to external systems?
2) Is there a trigger function at
   2.1) database layer?
   2.2) process layer?

Thanks a lot in advance for your feedback or a reference to compiere's
documentation.

Kind regards
Peter
