A 'Pick First Group'.


Sending HTTP response, confirming an email/jms message etc. This is because the confirmation or sending HTTP response has to done in the same session. When engine crashes these sessions are closed at their socket level. In such cases send response/confirm before checkpoint.

Both of them can be manipulated via the palette resources 'Get shared variable' and 'Set shared variable'.

A job shared variable is private to one instance of job or in other words each job has a fresh copy. In the case of shared variable the same copy is shared across all job instances. It can even be persisted and can survive BW engine restarts and even shared across multiple BW engines(when deployed using DB persistence).


The scope of user defined process variables is only the process in which it is defined.(Not even inside a sub process that is invoked from this process)


It can be used to serve the wsdl file of a SOAP Event Source to a (http) client.
Construct a process like: HTTP Receiver -> Retrieve Resources -> Send HTTP Response

Now the WSDL file for a SOAP service can be retreived using the http request


where 'path' is the folder path to the SOAP Event Source process and 'resourceName' is the name of the process

Example : http://purch:8877/Purchasing/GetPurchaseOrder?wsdl


SOAP request reply activity. If the business process needs to be exposed as SOAP service use SOAP Event Source in conjunction with SOAP Send Reply or SOAP Send Fault.
