Create SAP-Connected Nintex Workflows

Use the CData Cloud Hub to connect to SAP from Nintex Workflow Cloud and build custom workflows using live SAP data.

Nintex Workflow Cloud is a cloud-based platform where you can design workflows to automate simple or complex processes using drag-and-drop interactions — without writing any code. When paired with the CData Cloud Hub, you get instant, cloud-to-cloud access to SAP data for business applications. This article shows how to create a virtual database for SAP in Cloud Hub and build a simple workflow from SAP data in Nintex.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for SAP, allowing you to build workflows from live SAP data in Nintex Workflow Cloud — without replicating the data to a natively supported database. Nintex allows you to access data directly using SQL queries. Using optimized data processing out of the box, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc.) directly to SAP, leveraging server-side processing to quickly return the requested SAP data.

Create a Virtual MySQL Database for SAP Data

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

  1. Log into Cloud Hub and click Databases.
  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 Test Database.
  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 Nintex.

Connect to SAP in Nintex

The steps below outline creating a new connection for access to SAP the CData Cloud Hub from Nintex to create a new SAP data source.

  1. Log into Nintex Workflow Cloud
  2. In the Connections tab, click "Add new"
  3. Select MySQL as the connector and click "Connect"
  4. In the MySQL connection wizard, set the following properties:
    • Connection Name: name the connection (e.g., CData Cloud Hub SAP Connection)
    • Username: your Cloud Hub username
    • Password: your Cloud Hub password
    • Database Host: your Cloud Hub MySQL endpoint (e.g., myinstance.cdatacloud.net)
    • Database Name: the virtual SAP database (e.g., SAPERP1)
  5. Click "Connect"
  6. Configure the connection permissions and click "Save permissions"

Create a Simple SAP Workflow

With the connection to the CData Cloud Hub configured, we are ready to build a simple workflow to access SAP data. Start by clicking the "Create workflow" button.

Configure the Start Event Action

  1. Click the start event task and select the "Form" event
  2. Click "Design form"
  3. Drag a "Text - Long" element onto the Form and click the element to configure it
    • Set "Title" to "Enter SQL query"
    • Set "Required" to true
  4. Drag a "Text - Short" element onto the Form and click the element to configure it
    • Set "Title" to "Enter desired result column"
    • Set "Required" to true

Configure an "Execute a Query" Action

  1. Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
  2. Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
  3. Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
  4. Set "Retrieved column" to a new variable (e.g., "values")

Configure a "Send an Email" Action

  1. Add a "Send an email" action after the "Execute a query" action and click to configure the action
  2. Set the "Recipient email address"
  3. Set the "Subject"
  4. Set the "Message body" to the variable created for the retrieved column

Once you configure the actions, click "Save," name the Workflow, and click "Save" again. You now have a simple workflow that will query SAP using SQL and send an email with the results.
