Hello everyone,
While going through the configuration of SAP Fiori, I faced some errors, and still am not done. I think I have solved the first errors, so maybe someone else gets some help from reading what I did. And I could use some input on how to progress...
Here's what I have done so far: I only wanted to test "Approve Purchase Orders" and "Approve Requisitions". So I installed the components, configured them and got the error message: "No service found for namespace /IWPGW/, name TASKPROCESSING, version 0001".
Question: Do you need the "taskprocessing" service ("Approve requests" - which I understand to be used for a custom workflow"), if you only want to use "Approve Requisitions" and "Approve Purchase Orders"?
I installed the component IW-PGW 100 for Approve Requests, activated the service and configured it according to 2.4.1 in the guide with the link to backend system.
After activating this service, I got I got the same error that some other SCN member already did mention: "Task Facade not implemented for provider. [/IWBEP/CX_MGW_TECH_EXCEPTION] (error)". (For details from transaction /n/IWFND/ERROR_LOG see the image at the bottom of this post.)
I read that the problem tends to be a wrong System Alias. http://scn.sap.com/community/mobile/blog/2013/06/25/sap-fiori-ll06--define-system-alias-for-the-taskprocessing-service
(Question: What is the right "software version" to chose for the copied system alias? IWPGW/BPM, /IWPGW/BWF, or maybe ERP, since I want to connect an ERP? How can you tell which one to chose?)
My taskprocessing service had, as mentioned above, the original system alias with DEFAULT software version and local not checked.
So, I configured the "local" system alias as a copy of the ERP backend alias as described, deleted the original taskprocessing service with the default connection into the backend and replaced it with a service that has the "copied" system alias.
Now, I get the error message: "
A problem occurred while reading the data : Check the URL parameters and the scenario definition. To check the scenario definition, go to customizing for SAP NetWeaver Gateway and choose SAP NetWeaver -> Gateway Service Enablement -> Content -> Task Gateway Service -> Scenario Definition."
The scenarios for Approve Purchase Order and Purchase Requisition should be configured according to the guide. What's NOT configured is the "Task definition for Scenario" for the "Approve Request" service, since I don't know which workflow to define. We don't want to use a custom workflow so far.
The System Alias is the original system alias with connection to ERP, "local" not checked" and Software "Default". After changing the system alias in the taskprocessing service, I can't chose them anymore but only am offered the copied "local" alias. When I change that to the copied system alias (local) I don't get anything: no error message, no data, just the gray loading screen.
So, I would really appreciate some help what to do next to get something besides than this grey screen...
With best regards,
Thorben.
