Troubleshooting the Services Registry
Recently I set up the services registry for PI 7.1 EHP1 for a client of ours. Although it seemed like it would be a simple process, I ran into a 401 authorization issue and another issue where web services were not publishing to the services registry. Looking online there are a lot of people who ran into the same issues as I did, so I am providing, here, the steps to perform if your services registry isn’t working.
How To Debug ABAP Web Service on SAP Web Application Server (WAS)
One of the more confounding aspects of developing in the SAP space is the lack of good, low-level, helpful instructions. While this post is merely regurgitating information that is readily available elsewhere, it will be done in a manner that (hopefully) will actually be useful to vast majority of ABAP developers out there that, like me, find a lot of SAP’s implementation of web services on the ABAP stack confusing.
Debugging a web service on the ABAP stack of SAP Web Application Server is a very useful procedure to know. Here’s how you do it.
Changing The Function Interface of Web Service Enabled Functions
Today, I got an email from one of my co-workers at my client with a very good question. This developer had created an ABAP function to return SAP data. Then, he exposed this function as a web service. Due to changes in functional scope, he had to change the function interface. After he made all his changes and unit tested the ABAP code, he was surprised to find that his web service was still adhering to the old function interface. He tried deleting and recreating the web service, but ran in to problems. He was stuck in a pickle and needed a little push in the right direction.
Turn any SAP remote-enabled function module into a Web Service – Part 2
In my previous blog I showed the steps into turning a simple function module into an Enterprise Service. Now that we have the service defined in ECC, our next step is to configure it so an external application can call our newly created service.
I will show how to configure and test the Web Service on ECC with Service pack 14 and higher. Before Service Pack 14, the configuration is completed in ECC, however after SP14 the configuration is completed on the Java Stack.
Turn any SAP remote-enabled function module into a Web Service – Part 1
It still amazes me that not a lot of developers know that you can turn any existing SAP remote enable function module into a Web Service. It may sound like a challenging task, but it is just one of those things that you either know how to do it or you don’t. And to know how to do it only takes 15min to understand.
I have broken this down into 2 blogs Part 1 will show how to create the simple structured web service Part 2 will show how to configure and test the web service using SOAMANAGER and WSNAV
