Webflow step - error "XML tag <ProcessInstanceKey> not available"

[Griffiths, Mark]

It looks like your XML file is missing the workitem id.
 
Resolving these sorts of problems can be tricky, make sure:
 
- you have maintained anonymous logon data in SICF for the workflow_xml
service 
- you have configured SWR_WEBSERVER on both systems (when you test you
shouldn't get a logon prompt if SICF is OK).
- You have run RSWXML_REPAIR (name may not be quite right but it is in
some oss notes) in both systems
- You have set up possible agents for the calling, called and reference
workflow templates (steer clear of authentication rules until you get
the basic communication working) i.e. the agents at the 'header level'
of the template
 
When you test, both workflows should end up with at least 4 xml files -
read these and sometimes you will get extra error information.
 
You may also get problems with your workflows if your network isn't
configured, sometimes the systems find it difficult to talk to one
another, get your basis person to do an NIPING to make sure your reverse
DNS is all OK (no idea what this means but basis people will).  Also
check with basis that the ICM parameters are all set up in RZ10 for your
host and port.
 
Good luck, this sort of WF_XML communication is much more fun than
boring old RFCs!

available"
	
	

	Hi,

	 

	I am working on a webflow scenario that integrates a process
between two SAP systems -being R/3 Enterprise and SRM 4.0. The idea is
that a workflow in started in R/3 when an invoice is held. It collects
various pieces of information then starts a corresponding workflow in
SRM using a webflow activity, and should then wait until the SRM
workflow is complete. The SRM workflow will request creation of a
service confirmation to an agent. Once this is complete, the SRM
workflow ends and the R/3 workflow will continue from there.

	 

	Because I haven't worked with the webflow step before, I started
by just creating a simple example. In the example, an R/3 workflow fills
a container element with the value of a user-id and passes it to an SRM
workflow which sends an email to this user. A reference workflow is
created with the same container element. I just wanted to see the
process working so I know how to write up a spec for the real workflow
scenario mentioned above and be sure that it is going to work!

	 

	I have the example working to the point where the initiating R/3
workflow successfully sends the wf-xml message to the SRM system, which
starts the SRM workflow (passing the container value of my user-id
correctly). The SRM workflow completes ok. But before anything else can
happen, the R/3 workflow goes into error. The error message is "XML tag
<ProcessInstanceKey> not available". When I checked the request /
response messages (with transaction SWXML), this is what the
"CreateProcessInstance.Request (received response)" looks like:

	 

	<?xml version="1.0" ?> 

	- <WfMessage Version="1.1"
xmlns="http://www.wfmc.org/standards/docs/Wf-XML">

	- <WfMessageHeader>

	  <Response /> 

	
<Key>HTTP://stlmelhsapd.stlmel.bsl.net:8002/SAP/BC/WORKFLOW_XML/?~protoc
ol=04&~localkey=WS90200001</Key> 

	  </WfMessageHeader>

	- <WfMessageBody>

	- <CreateProcessInstance.Response>

	  <ProcessInstanceKey /> 

	  </CreateProcessInstance.Response>

	  </WfMessageBody>

	  </WfMessage>

	 

	So it seems like the response from SRM is not being correctly
formed when it responds to the initial request from R/3.

	I found a message previously in this group which suggested that
it might be an authentication problem. I tried using an authentication
rule in the header of the SRM workflow (passing a user and password to
it) but it didn't make any difference. Does anyone have any idea what is
going wrong or what I should check?

	Thankyou!

	 

	Kind Regards,
