Consume PCA Sales OData Feeds in SAP Lumira

You can use the CData API Server and the ADO.NET Provider for PCA Sales (or any of 200+ other ADO.NET Providers) to create data visualizations based on PCA Sales data in SAP Lumira. The API Server enables connectivity to live data: dashboards and reports can be refreshed on demand. This article shows how to create a chart that is always up to date.

Set Up the API Server

Follow the steps below to begin producing secure PCA Sales OData services:

Deploy

The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.

The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.

Connect to PCA Sales

After you deploy the API Server and the ADO.NET Provider for PCA Sales, provide authentication values and other connection properties needed to connect to PCA Sales by clicking Settings -> Connection and adding a new connection in the API Server administration console.

In order to authenticate using the OAuth, specify the following:

• AuthScheme: Set to OAuth.

In order to authenticate using the OAuth Password, specify the following:

• AuthScheme: Set to OAuthPassword.
• User: Enter the PCA Sales username.
• Password: Enter the PCA Sales password.
• ServiceId: Enter the Service ID used to connect tot he PCA API server.
• ServicePassword: Enter the Service Password for the above Service ID.

For both authentication methods, specify the following:

• Data Center: Enter the name for the PCA API Server.
• Default Data Area: Enter the data area to which you want to connect.
• Product Code: Enter "Kon20" or "Acc20."

For more information, refer to the Help documentation.

When you configure the connection, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

You can then choose the PCA Sales entities you want to allow the API Server access to by clicking Settings -> Resources.

Authorize API Server Users

After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.

Connect to PCA Sales from SAP Lumira

Follow the steps below to retrieve PCA Sales data into SAP Lumira. You can execute an SQL query or use the UI.

1. In SAP Lumira, click File -> New -> Query with SQL. The Add New Dataset dialog is displayed.
2. Expand the Generic section and click the Generic OData 2.0 Connector option.
3. In the Service Root URI box, enter the OData endpoint of the API Server. This URL will resemble the following: https://your-server:8032/api.rsc
4. In the User Name and Password boxes, enter the username and authtoken of an API user. These credentials will be used in HTTP Basic authentication.

5. Select entities in the tree or enter an SQL query. This article imports PCA Sales MasterLot entities.

6. When you click Connect, SAP Lumira will generate the corresponding OData request and load the results into memory. You can then use any of the data processing tools available in SAP Lumira, such as filters, aggregates, and summary functions.

Create Data Visualizations

After you have imported the data, you can create data visualizations in the Visualize room. Follow the steps below to create a basic chart.

1. In the Measures and Dimensions pane, drag measures and dimensions onto the x-axis and y-axis fields in the Visualization Tools pane. SAP Lumira automatically detects dimensions and measures from the metadata service of the API Server.

   By default, the SUM function is applied to all measures. Click the gear icon next to a measure to change the default summary.

2. In the Visualization Tools pane, select the chart type.
3. In the Chart Canvas pane, apply filters, sort by measures, add rankings, and update the chart with the current PCA Sales data.
