How Easy It Is To Consume Function Module as Web service and Connect it Using SAP Cloud Platform Integration

In this blog, I shall explain how we can  generate WSDL from existing function module and use it in SAP Cloud Platform Integration

Benefits:

We can use all the existing standard BAPIs along with custom BAPIs from SAP  ERP instead of developing new web services

Background:

RFC adapter in SAP Cloud Platform Integration  yet to be built, hence as of now, we can connect to RFC via a SOAP Adapter in SAP Cloud Platform Integration.

We can expose the RFC as a soap service using SE37 and configure the endpoint using SOAMANAGER.

However, there is an easier way to do the same, just by using a particular format to generate the wsdl file.

In the following scenario, we’ll be using an RFC at the receiver end via a SOAP receiver channel in SAP Cloud Platform Integration

Prerequisites:

The BAPI needs to be remote enabled.

Procedure:

1. To obtain the wsdl of the BAPI, follow the below format: http://<host>:<port>/sap/bc/soap/wsdl11?services=<BAPI Name>&sap-client=<client>&sap-user=<user>&sap-password=<password>

You can test the wsdl in the browser and then import it in the wsdl folder in SAP Cloud Platform Integration.

2. Create a SOAP adapter and use the URL in the location field (towards the end of the wsdl file) in the address.

The address will be in the form: http://<host>:<port>/sap/bc/soap/rfc

Use the wsdl in the SAP Cloud Platform Integration . The service, endpoint and operation fields will get populated automatically.

3. Save and test the scenario.
