Creation of RESTful Webservice in SAP

As you all aware of that creation of SOA (System oriented architecture) web service using FM. Now let’s create a REST(Representational state transfer) web service which is getting much attention now a days.

Recently I have been given with a requirement to create a REST( Representational state transfer) web service which returns the sales order details in XML format.

Business requirement: Consumer want to get the details of sales order from the SAP by passing the sales order number as ID through URL.

What is REST ful web service?

It’s a named resource which can be accessed using the URL containing the ID (In our case Sales order number ) of the resource in distributed environment.


With the help of SCN and Wiki documents I have created Web service as below.

Step1: Create a handler class which is having the business logic to get the sales order details

           Go to se24 enter the class name

Step 2: Now we need to implement the interface IF_HTTP_EXTENSION

You can see the method HANDLE_REQUEST from the interface IF_HTTP_EXTENSION.We will use this method in future to implement business logic.

Step 3:Write below code in the HANDLE_REQUEST method

Source code:


  data:lv_path type string,

       lv_data type string,

       lt_data type table of string.

  types:begin of ty_head,

        VBELN type vbak-VBELN,

        KUNNR type vbak-KUNNR,

        VKORG type vbak-VKORG,

        end of ty_head.

  data:ls_head type ty_head,

       lt_list type table of BAPIORDERS,

       ls_list type BAPIORDERS,

       XML_OUT type string.

* get the request attributes

  lv_path = server->REQUEST->get_header_field( name = ‘~PATH_INFO’ ).


* Get the sales order details

  select single vbeln



           into ls_head

           from vbak

          where vbeln = lv_path.

* Convert the data to  XML format


               SOURCE TAB = ls_head



* Set the converted data to Browser

  server->response->set_cdata( data = XML_OUT ).


Step4: Go to transaction SICF and click on Execute button

Step 5: Create a child node under the services hierarchy by right click on the node. I have created services in the following path

Default host->SAP->bc

Step 6: Enter the service name click to continue

Added service will be under the respective hierarchy as below

Step 7: Double click on the service zrest_service then below screen will appear

Step 8: Go to Handler list tab and give the handler name which we created earlier as ZCL_SALES_ORDER_HANDLER

Step 9: Save and activate the service as below

Step 10: Now test the service

Step 11:Give sales order number in URL and click F5

Note: To debug the web service you have to put external break point in the method HANDLE_REQUEST
