How to create Visio diagrams from SAP Ariba Source Data

Automate the process of entering data into Visio diagrams and keeping your diagrams up to date with the CData ODBC Driver for SAP Ariba Source. The driver surfaces SAP Ariba Source data as an ODBC data source that can be accessed by applications with built-in ODBC support like Microsoft Office. This article shows how to create a simple diagram to start brainstorming about Visio projects linked to SAP Ariba Source data.

Connect to SAP Ariba Source as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

In order to connect with SAP Ariba Source, set the following:

• API: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Supplier, Sourcing Project Management, or Contract API based on your business role (possible values are SupplierDataAPIWithPaginationV4, SourcingProjectManagementAPIV2, or ContractAPIV1).
• DataCenter: The data center where your account's data is hosted.
• Realm: The name of the site you want to access.
• Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

If you are connecting to the Supplier Data API or the Contract API, additionally set the following:

• User: Id of the user on whose behalf API calls are invoked.
• PasswordAdapter: The password associated with the authenticating User.

If you're connecting to the Supplier API, set ProjectId to the Id of the sourcing project you want to retrieve data from.

Authenticating with OAuth

After setting connection properties, you need to configure OAuth connectivity to authenticate.

• Set AuthScheme to OAuthClient.
• Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.

  For more information on creating an OAuth application, refer to the Help documentation.

Automatic OAuth

After setting the following, you are ready to connect:

APIKey: The Application key in your app settings. OAuthClientId: The OAuth Client Id in your app settings. OAuthClientSecret: The OAuth Secret in your app settings.

When you connect, the provider automatically completes the OAuth process:

1. The provider obtains an access token from SAP Ariba and uses it to request data.
2. The provider refreshes the access token automatically when it expires.
3. The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.

Connect SAP Ariba Source Data to Diagrams

Follow the steps below to use the Data Selector Wizard to import data into your diagram.

1. Open Visio and click File -> New. Open the Brainstorming template.
2. On the Data tab, click Link Data to Shapes.
3. Select the ODBC option and select ODBC DSN.
4. Select the DSN for SAP Ariba Source, select the table you want to import, and finish the wizard. This article uses Vendors as an example.

Link SAP Ariba Source Entities to Shapes

Follow the steps below to create a simple diagram that shows how to create shapes from your data, one of the ways to link SAP Ariba Source entities to shapes:

1. Click Brainstorming Shapes and drag a main topic onto the drawing page. Enter Vendors as the text of the main topic.
2. Click Topic.
3. Select a row in the External Data window and drag it onto the drawing page.
4. Right-click the Topic shape and click Data -> Edit Data Graphic.
5. Click New Item.
6. In the Data Field menu, select a column. In the Displayed As menu, select how to display them.
7. Drag a few other SAP Ariba Source entities onto the drawing page and add association lines back to the main topic, Vendors. New topics have the same configuration: Numeric columns displayed in data bars stand out in contrast to other Vendors entities.

You can refresh your diagram from the Data tab, synchronizing your shapes with the external SAP Ariba Source data.
