Problem using Service TaskProcessing in Fiori Workflow Scenario

[Former Member]

Hey all,

I'm facing a problem using the workflow service TaskProcessing within the Fiori Launchpad. I get a HTTP request failed caused by a RFC call.

I think the error is raised while reading the decision options of the workitem. In Fiori Launchpad the number of workitems is correct. And some data is also been read when I navigate into the app.

Our gateway server is currently located on a crm System. Hopefully we get a central stand alone gateway server soon. The workflow which I want to access is in the crm system so the RFC connection is "LOCAL_PGW". Maybe I did something wrong in the customizing?

Actually I really don't know where to look. Where can I find the function call of  /IWWRK/WF_TGW_TASK_DET_READ? I don't even get any hints reading the error log.

I'm thankful for any help.

Best regards.

We tried to integrate a workflow scenario in a different backend and it worked. So there might be something wrong with the local System alias or RFC connection NONE!? But what?

The error log:

The error text in english is the same like in the first picture of this thread.

Not sure, but it might be related.

When a RFC is called remotely, interface parameters' type checks are not done statically for obvious reasons. But when local, it is strict.

On an other note,

Did you implement BADI /IWPGW/ES_TGW_TASK_DATA?

Hi,

In the system alias LOCAL_PGW, have maintained value for system id and client? You need to create RFC destination that would point to your backend client and instead of NONE that value should be set while creating system alias.

Navya, that was it. Thank you very much. Using a RFC connection directed to the local system instead of NONE solved the problem. Thanks to you too, Krishna.

Best wishes from germany.

Hi Navya,

I'm on the local system (same to the gateway) so the aliases are LOCAL and LOCAL_PGW. They are configured like it is shown in the picture. !?

Thanks.
