If you want to consume SAP data through non SAP application then this is a very useful document for you. It gives you a step by step, easy guide to build it yourself. We can, using SAP Web Services, read and write SAP data using non SAP applications. This option has been available for a long time now. Please do remember with the advent of UI5 and Fiori there are now more ways to utilise SAP data externally.
The example here shows how to read the data but can be enhanced to write back to SAP as well. Please check if you have the relevant SAP license.
This example was done on:
1) Microsoft Visual Studio 12
2) SAP ECC 6.0
I am writing down the steps which if followed properly will help you do it yourself.
The example here is to demonstrate how we can read vendors in SAP and pass it on to a .Net Application.
The prerequisites are:
1) Basic knowledge of SAP ABAP, especially RFC
3) Basic knowledge of Visual Basic/C#
Here is a list of, high level, steps on how to do it:
1) Create an RFC Enabled Function Module in SAP
a) In our example, we will create an RFC which accepts a country code and returns all the vendors for that country from an SAP server
2) Create a Web Service for the function module so that it can be consumed by other service based applications
3) Setup the Web Service
4) Create a small Visual Basic Project to show how the country selection be passed to the Web Service and utilise the list of vendors returned from SAP
We will start with a list of activities to be carried out in SAP first.
