Let us explore the SAP API Business Hub and learn about some of its features. This is going to be a quick introduction for those who are interested in SAP Integrations (specifically those that involve APIs). Some are not yet aware of this SAP API Hub so I decided to write briefly on this topic. Hopefully, you are able to get an insight or at least find some helpful references / guides for your own development needs.
This post will focus on introducing the application named Postman as a tool to help SAP Functional Consultants in their SAP testing. This is not going to be a full blown technical how-to guide for developers (I might touch base on that in the future with a separate post). Instead, the goal of this post is to simply help functional consultants get acquainted with Postman and provide some high-level use cases.
In this post we will quickly discuss how to troubleshoot and resolve SAP IDoc Error “Error Passing Data to port” or Error Text “Could not find code page for receiving system”. We will additionally cover how to reprocess the erroneous IDoc for it to successfully post and the key difference between transaction code WE20 vs WE21.
