A simple REST Web-service from ECC called from a HTML5 screen

Introduction

Recently we were directed to design OS agnostic RF screens for one of our business partners. We envisioned a web browser based screen which can be called from both our android & windows based RF guns. We did not want to take the module pool ITS approach & our ECC system is one of the lower level versions so we could not do a UI5-Gateway solution. After reading across these forums we decided to implement a standalone REST based web-service in ECC which can be called from a HTML5 screen.

ABAP is Evolving

I had the privilege of attending SAP TechEd in Las Vegas last week as part of the SAP Bloggers Program.

In the keynote Bernd Leukert announced that the SAP Cloud Platform ABAP Environment was Generally Available. When you say it like that it seems like an impenetrable wall of SAPanese – but the announcement was still greeted with spontaneous applause from the audience.

SAPGUI is dead – long live SAPGUI

I realized that the SAPGUI will come to an end. That makes me pretty sad. But I think the new technologies and Cloud applications will conquer the SAP planet.

So I decided to make a project public that a former colleague and I started years ago. I have the feeling that if I do not publish it, it will be totally useless and unineteresting the next two years. But I want this project to survive.

Accessing Local File in Background Mode

Introduction:

This blog covers how to access a local file in background job in SAP. Basis knowledge of ABAP is required to understand the concept.

Its applicable for SAP Netweaver 7.4 onwards.

But let’s say there is a requirement where i am getting the file in email. Then I am placing the file in my local PC. After that my need is that a program which is running in background on application server, should process the file.

Register XSOdata servies into SAP Gateway

Complete procedure for registering xsodata services which are developed in HANA to SAP Gateway.

For any requirement in which if we develop xsodata services and use it while creating UI5 application in web ide, We can directly take that xsodata service URL from WEB ide or we can also register the service into SAP gateway and select the specific URL as a odata service URL to avoid issues while deploying app to SAP UI5 repository.

How to find a predefined VDM for a selected S/4HANA table

Purpose 

This blog illustrates how to find the predefined VDM (template of the CDS View for business entities  in S/4HANA)  for a table, e.g. finding the VDM “I_ProfitCenter” for the table CEPC.

This method should help reduce the development effort, by using a predefined VDM instead of creating custom CDS Views for the business entities in S/4HANA.
