Introduction

In our current project, the client has decided to replace SAP CRM with Salesforce.com (SFDC – Online CRM). We are doing a POC to integrate SFDC with SAP ECC using SAP XI.

I would like to thank Bhavesh Kantilal, Saravana Kuppusamy, Harsh, Santhosh, Unnamalai and Pragya for helping me out during the implementation of this Proof of Concept.

Overview

Salesforce.com (SFDC) is a Software as a Service (SaaS) company that distributes business software on a subscription basis. It is best known for its Customer Relationship management (CRM) products. This article explains various steps involved in the integration of SFDC with SAP ECC using SAP PI 7.1. SFDC exposes a web services interface that can be accessed using an Enterprise WSDL. Some of the web services are Create Account, Update/Upsert/Delete Account, Query Account Details etc.,

In the article, I will show how to call a simple SFDC web service - getServerTimestamp, which when called, gives the server timestamp as response. Once we achieve this, we can implement any of the web service that SFDC offers, with some modifications to the WSDL file.

Step by Step Execution

Create developer account in SFDC

Register yourself at http://developer.force.com. You will get the username and password by email. You need to login to SFDC and get the security token, which should be appended with the password, while calling the login web service of SFDC. To get this, login to http://developer.force.com and then go to Setup->Personal Setup->My Personal Information->Reset My Security Token. You will receive the security token by email.

Download the Enterprise WSDL

Login to http://developer.force.com and go to Setup->App Setup->Develop->API. Under Enterprise WSDL, click on “Generate Enterprise WSDL” and save it as a .wsdl file on your local machine.

Testing the WSDL using SOAPUI

We did this optional step to see the WSDL structure and to test the various web services exposed in the Enterprise WSDL. Below steps will help you understand what we did.

a. To implement any business scenario(e.g. Create an Account in SFDC database, query Account details from SFDC or to Update Account details in SFDC, etc) using the WSDL approach, SFDC will want you to call the corresponding web service(query, Create, Update, Upsert etc).

b. But, to call these web services, we will need an additional sessionId/serverUrl attributes to be set in the SOAP Header of the web service request. To get this, we have to first call the login web service, which returns the sessionId & the serverUrl. To call the login web service, we will need the username/ (password+security token) (got during the registration process).

Below is the screenshot of the login web service request.

Once we receive the Session ID and Server URL, we have to set them in the header of getServerTimestamp web service and get the Server‟s timestamp as response. Below is the screenshot for the same.

Implementation Using SAP PI 7.1

Now, we will implement the same using SAP PI 7.1.

Design Steps

Below are the design steps that we need to perform in the Enterprise Service Repository:

Create the namespace and import the Enterprise WSDL as an external definition.



© 2010 SAP AG 7

Create an Outbound Synchronous Service Interface. Assign the External Definition‟s loginRequest as the Output message.



© 2010 SAP AG 8

Similarly, assign getServerTimestampResponse from the external definition, as the input message.

Create an Inbound Synchronous Service Interface. Assign the External Definition‟s getServerTimestampRequest as the Output message and getServerTimestampResponse as the input message, as shown in the above screenshot.

Create a message mapping. Load the loginRequest at the Source side and getServerTimestampRequest at the target side.



© 2010 SAP AG 10

Create a UDF (SampleUDF1) and use Dynamic Configuration to set the parameter TServerLocation with the Server URL that we received in the response message of the login web service. We found out that this Server URL is always constant, so we have manually set this in the UDF. We can assign this UDF to any node in the target.

We will create a Java Mapping Program to obtain session ID and server URL by doing a SOAP lookup, and set these fields in the SOAP Envelope. Create a new Java Mapping Class using SAP NetWeaver Developer Studio. We will use the DOM parser to parse the SOAP response. In the execute() method, we will call two functions. In the first one, we will pass the username and password (password+security token, without „+‟) to the SOAP lookup API to login to the SFDC and get the Session ID. For details regarding SOAP Lookup, refer to Bhavesh‟s Blog in the Related Articles section.

In the second function, we will add the SOAP Envelope to the incoming payload and set the sessionId field in the SOAP Header. For the complete Code, refer to uaruna‟s wiki page. You can also find this link under “Related Contents” section, at the end of this article.

Export the Java Class as a .JAR file and import it into the ESR under Imported Archives.

Create an Operation Mapping and use the Message mapping and Java mapping in sequence.

Configuration Steps

Below are the configuration steps that we need to perform in the Integration Directory:

Create Business Components for the Sender ECC system and SFDC Receiver.

Create a Receiver SOAP Communication Channel (Channel1). Since this channel will be used in the SOAP lookup, it should not be associated with any Receiver Agreement. In this channel, we provide the Target URL (https://www.salesforce.com/services/Soap/c/18.0) and SOAP Action (login).

https://www.salesforce.com/services/Soap/c/18.0

Create another Receiver SOAP Communication Channel (Channel2). Settings will be as follows:

o Provide Target URL (it will be over written by the Dynamic Configuration).

o Check “Use Adapter-Specific Message Attributes” and “Variable Transport Binding”, since we are setting the TServerLocation attribute using Dynamic Configuration within the UDF.

o Under Conversion Parameters, check “Do Not Use SOAP Envelope”, as we are manually building the SOAP Envelope, to set the fields in the SOAP Header.

o Provide the SOAP Action (getServerTimestamp).



© 2010 SAP AG 15

o Since we are using the SOAP Adapter with option “Do Not Use SOAP Envelope”, the content type of the incoming message will be “application/xml”. We need to change it to “text/xml”. To achieve this, we need to use the adapter module “MessageTransformBean” before the XISOAPAdapterBean and set the parameter “Transform.ContentType” to “text/xml”.

Create Receiver Determination and Interface Determination with ECC System as the sender and Business Component for SFDC as the receiver. In the Interface Determination, use the Operation Mapping and Inbound Interface that we created in ESR.

Create a Receiver Agreement and provide the Communication Channel (Channel2).

Testing the Interface

Steps to be followed for testing this interface are as follows:

1. We can trigger this interface from the sender ECC system in two ways.

a. ABAP Proxy

b. RFC Call.

(For testing purpose, we can even use Runtime Workbench‟s test tool or an HTTP Client)

2. We don‟t have to pass any values in the source message, as we are directly passing the credentials in the java Mapping. Below is a screenshot of RWB‟s test tool.

3. The screenshot of the request message is below:

4. After the SOAP lookup, this is how the message looks like:

5. Screenshot of the response message
