The Fiori application of SAP interacts with the background through OData. You may encounter an error message like this when using the Fiori application:

This error message contains no clues to help partner or the customer locate the root cause of the problem.

Here are the steps to identify the root cause of the problem in the background.

1. Use the transaction code / IWFND/ERROR_LOG on the Fiori foreground system to find the error log corresponding to the current OData error:

For the distinction between Fiori front-end and back-end systems, refer to my Wechat official account article on the three deployment methods of SAP Fiori applications.

two。 Click the button "Active Source" on the toolbar. We are then automatically taken to the location of the code that threw the error message, line 86 of the following figure. This code is the framework code for error handling in the Fiori foreground system, and we set a breakpoint on line 86.

Return Fiori UI to reproduce the error, and the breakpoint is triggered. The default call stack is the breakpoint set in the figure above, that is, inside the method HANDLE_RFC_FAILURE. At this point we jump to the outer layer of the call stack, the method CALL_BACKEND, as shown in the following figure. The content of the exceptions parameter lv_rfc_message of this method is the specific error message.

At this point, the study on "how to find out the root cause of OData service error" is over. I hope to be able to solve your doubts.
