Fiori Approval RFC Error

[Former Member]

Hi Experts,

I’m at a customer implementig Fiori Approve Purchase Order, Approve Purchase Requisitions, and Approve Travel Expenses.

While running the Approve Purchase Order App, I get the following error:

I see that it brings back the workitem assigned to the user (so I guess communication is fine but..)

When I run it on the gateway client I get this error:

Error RFC: An exception occurred that was not caught.

So I go through the error log. The flag backend error is checked. I run backend monitor and nothing is displayed.

Please Help.

Hi Masa,

Thank you for your fast response.

The problem seems to be when I call:

/sap/opu/odata/SAP/GBAPP_POAPPROVAL;mo/WorkflowTaskCollection(SAP__Origin='DEVCLNT122',WorkitemID='000000022470')/HeaderDetails?$expand=ItemDetails%2cNotes%2cAttachments%2cItemDetails%2fLimits&sap-client=350

I've debugged finding that the issue occurrs when calling:

LV_REQUEST_CONTEXT is generated a few lines before at /iwfnd/cl_mgw_runt_rclnt_utils=>serialize_request_details(

Is it correct that RFC_DEST is empty?

Configuration of the SAP System Alias:

Configuration of the RFC Destination:

Conexion Test:

Authorization Test:

Other applications are running ok communicating with the backend which is why I guess there's no real problem with the RFC Configuration. Please help.

Hi I could debug on the backend the problem:

Any idea what might be going on?

Thanks in advance.

Hi Facundo,

Please follow the instruction in the dump. It gives some search keyword for finding notes.

Probably your backend SP is old and mandatory notes are missing.
