How to Integrate SAP Leonardo with Microsoft SharePoint

Understanding SAP Leonardo and Microsoft SharePoint Integration

• SAP Leonardo is a comprehensive system that integrates emerging technologies, while Microsoft SharePoint offers secure collaboration and document management.

 

• The integration of these platforms helps in automating workflows and enhancing data accessibility across business processes.

Prerequisites

• Ensure you have administrative access to both SAP Leonardo and Microsoft SharePoint systems.

 

• Make sure the SAP Leonardo's IoT service is correctly configured and running.

 

• You should have a working knowledge of both the Microsoft SharePoint API and SAP API Management.

Setting Up SAP API Management

• Go to your SAP Cloud Platform cockpit and select the API Management service.

 

• Create a new API proxy to connect with SharePoint's REST APIs.

 

• Configure the authentication method, such as OAuth 2.0, to ensure secure data transfer between systems.

Configuring Microsoft SharePoint

• Navigate to your SharePoint admin center, and set up an App registration for SAP Leonardo.

 

• Generate a client ID and client secret necessary for the OAuth token exchange.

 

• Assign appropriate permissions to allow SAP Leonardo to access SharePoint data.

Creating Connectivity with SAP Leonardo

• Utilize the SAP Cloud Platform's connectivity service to create an endpoint for SharePoint APIs.

 

• Use the endpoint to set up secure communication between SAP Leonardo and SharePoint.

 

• Ensure that both systems are using HTTPS to maintain secure communications.

Building an Integration Flow

• In the SAP Cloud Platform Integration, create a new integration flow to define how data moves between SAP Leonardo and SharePoint.

 

• Use connectors and flow steps to sequence operations like data fetch from SharePoint and send it to SAP Leonardo.

 

• Deploy the integration flow on the cloud platform to initiate real-time data exchanges.

Writing Sample Code to Access SharePoint Data

using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

// Sample method to get SharePoint list data
public async Task GetSharePointData(string siteUrl, string listName, string accessToken)
{
    using (HttpClient client = new HttpClient())
    {
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);
        
        var endpointUrl = $"{siteUrl}/_api/web/lists/getbytitle('{listName}')/items";
        HttpResponseMessage response = await client.GetAsync(endpointUrl);
        
        if (response.IsSuccessStatusCode)
        {
            string responseBody = await response.Content.ReadAsStringAsync();
            Console.WriteLine(responseBody);
        }
        else
        {
            Console.WriteLine($"Error: {response.StatusCode}");
        }
    }
}

Testing the Integration

• Initiate data requests from SAP Leonardo and verify that SharePoint responds correctly with the required data.

 

• Test scenarios for both data input and output, ensuring that workflows are correctly synchronized.

 

• Address any errors or issues in integration using SAP's monitoring tools and logs.

Finalizing and Go-Live

• Conduct a thorough review of security settings on both platforms to prevent unauthorized access.

 

• Optimize the integration flow for performance, ensuring minimal delay and high throughput.

 

• Once verified, proceed to move the integration into the production environment and monitor its performance regularly.
