SAP Netweaver Gateway and OData. Section VII. Help with Debugging, Trace, Cache Cleaning, and F4, We anticipate that by this point, every reader is familiar with the process of creating projects in SEGW, mapping data models, creating services, and testing URIs. assuming you have completed the six SAP Netweaver Gateway and OData Services courses before. If not, kindly take a moment out of your hectic schedule to educate yourself over the next few days. We think that a solid understanding of OData and SAPNetweaver Gateway development ideas is a must for every ABAPer.
Our advancements would not be as straightforward as they were in the instructional exercises once we began working on actual projects.We see strange problems and failures related to code, configuration, and authorization. Being an ABAPer, we must
I’ll explain to you in this post how any developer can keep track of problems and errors in the OData models. What can be the greatest ally of an ABAPer in identifying problems and resolving errors. You guessed correctly. ABAPer relies on its Debugging and Tracing Tools for survival. Allow me to demonstrate how to trace and debug any SAP Netweaver Gateway service.
- OData Services Debugging
Let’s examine the basic model as it is shown below.
Simply add the expression “&sap-ds-debug=true” at the end if you wish to debug the data now. And you believed that “/h” was necessary. Correct? That is still something you can do.However, it is more easy to pass the “&sap-ds-debug=true” argument in the URL when debugging services.
Click the top-most Execute button. Additional tabs such as Body, Request, Response, Server, and Runtime appear on the screen below. Examine every tab to comprehend the functionalities. Here are a few pertinent screenshots that should go without saying.Please feel free to write us with any more queries, and we would be pleased to address them.
In the ‘Server’ section it will show the path.
Additionally, this debug syntax can be used directly in the web server’s URI. It will assist us in debugging and understanding the flow.

- OData Trace Services
We can better grasp how to trace any OData service by following the steps below.
carry out the “/IWFND/TRACES” transaction.
Choose the two boxes above, then hit return or enter.
Check the “Payload Trace” and “Performance Trace” tabs now.
i. Trace of Performance
The time required for each step of the process is shown in the graphic above.
Select the “Trace Details” button and the first line.
Checking the “Source Code,” “Payload Trace,” “Error Log,” and so on is possible.
To view the “Trace Details,” click the second line in the trace log.
ii. Payload Trace
select on ‘HTTP Header’
‘HTTP Body->Original Payload’.

- Clearing the Cache
Execute the “/IWFND/CACHE_CLEANUP” transaction.
Occasionally, after modifying or repairing any code, the browser does not display the changes. In certain situations, the cache needs to be cleared or updated.Recall that we also experience comparable problems with Workflow modifications. Additionally, in order for the Workflow update to take effect, we must run a specific t-code. What does the t-code stand for?
- OData Services F4 Assistance
We might occasionally need to use the Web Server’s SAP Search Helps. In other words, we wish to incorporate search capabilities into our OData Services-consuming applications. We don’t really need to worry. As demonstrated below, achieving this is simple.
next move on to the relatively simple process of choosing the fields and mapping them in accordance with the requirements.
I hope that everyone who uses ABAPers will find this material useful when they begin working on genuine projects. Everybody knows that their programs can have 101 bugs or problems. But every flaw can be fixed and every problem can be solved as long as we know how to diagnose it using the Trace and Debugging Tools.
