SAP products viz. Business Intelligence (SAP BW), Customer Relationship Management (SAP CRM), Supplier Relationship Management (SAP SRM), Business Objects (SAP BO), SAP Portal (ESS/MSS) and others were either already web based or later made web enabled. Many times, ECC customers are faced with a common question – How to access SAP anytime anywhere from a browser, without installing anything on the workstation?  ITS, BSP, Webdynpros, Web services, Java / NET connetor are some of the options SAP Netweaver provides as a development technology and runtime environment for SAP applications, either standard or custom, so that they can be accessed via a browser.

This blog is a part of 6 blog series on Web Enable SAP and here we will discuss the 6th option for web enable SAP.

Options for web enabling are:

  1. ITS – Internet Transaction Server
  2. BSP – Business Server Pages
  3. ABAP Webdynpro
  4. Java Webdynpro
  5. ASP/JSP/.NET /Perl/Other Web development technology
  6. Creating a web service inside SAP

Let us briefly try to understand the 6th option:

Creating a web service inside SAP:
The last option is where there is no user screen but some legacy application needs to connect to SAP and get some information e.g. Accounts Payable – List of Invoices due for payment. In such cases we can use/develop a web service inside SAP so that the legacy application can call this web service and get the required information.

Pros:

  • This is the de-facto standard for interfacing technology over the web.
  • The connecting application can be built on any technology – .Net/Java/etc. Since the interfacing is via a Web Service, the technology does not matter.

So far we have discussed in brief all the available six choices. Knowing all this a question comes to our mind – which option should be used? Well this depends upon the requirement. In my next blog we would consider a practical scenario and evaluate the pros and cons of the above six options and be able to come to a conclusion. Thanks in advance.
