Create SAP-Connected Business Apps in AppSheet

AppSheet provides a no-code development platform for application software, which allows users to create mobile, tablet, and web applications. When paired with CData Connect Server, you get instant access to SAP data for business applications. This article shows how to create a virtual database for SAP in Connect Server and build a simple app from SAP data in AppSheet.

CData Connect Server provides a pure SQL Server interface for SAP, allowing you to easily build reports from live SAP data in AppSheet — without replicating the data to a natively supported database. As you build visualizations, AppSheet generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to SAP, leveraging server-side processing to quickly return the requested SAP data.

Getting Started

Create a Virtual SQL Server Database for SAP Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "SAP" from Available Data Sources.
3. Enter the necessary authentication properties to connect to SAP.

   You can connect to SAP systems using either librfc32.dll, librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.

   If you are using the SOAP interface, set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section.

   Otherwise, set Host, User, Password, Client, and SystemNumber.

   Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.

   For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SAP data from AppSheet.

Connect to SAP in AppSheet

The steps below outline connecting to CData Connect Server from AppSheet to create a new SAP data source.

1. Log into AppSheet.
2. Click the letter icon in the top-right corner, then select Account Settings.
3. Click the Sources tab and click + New Data Source. Then, select Cloud Database.
4. Set the connection information to the following:
   • Type: SQLServer
   • Server: the endpoint for your instance, including port, for example, CONNECT_SERVER_URL,3306
   • Database: the virtual database, for example, SAPERP1
   • Username: a Connect Server user with permissions for the database
   • Password: the password for the above Connect Server user
   • SSL: Require SSL
5. Click Test. Then, click Authorize Access.

Create an App

Once you create the data source for SAP, you can start building apps on SAP data.

1. Start by clicking + Create -> App -> Start with existing data.
2. Name the app and select an appropriate category, based on your data. Then, click Choose your data.
3. Select the newly created data source (e.g., SAPERP1).
4. Select the table or view with the data you want.

At this point, you can configure the design of your app, selecting which columns from the selected table to display, use as labels, and more. Preview the app in the preview panel and then publish or share it when ready.
