About SAP HANA

SAP HANA is a high-performance in-memory database that accelerates data-driven, real-time decision-making and actions, and supports all workloads with the broadest advanced analytics on multi-model data, on premises and in the cloud.

SAP HANA Connector

The SAP HANA Connector loads data into Incorta from SAP HANA databases. The connector uses a sqljdbc42.jar file that is included with the Incorta customer release distribution. You can find the JAR file in the following directory: {path to IncortaNode}/runtime/lib

The SAP HANA connector supports the following Incorta specific functionality:

Feature	Supported
Incremental loading	✔
Encryption at ingest
Performance Optimization	✔
Webhook Callbacks	✔

Steps to connect SAP HANA and Incorta

To connect SAP HANA and Incorta, here are the high level steps, tools, and procedures:

• Create an external data source
• Create a schema with the Schema Wizard
• or, Create a schema with the Schema Designer
• Load the schema
• Explore the schema

Create an external data source

Here are the steps to create a external data source with the SAP HANA connector:

• Sign in to the Incorta Direct Data Platform.
• In the Navigation bar, select Data.
• In the Action bar, select + New → Add Data Source.
• In the Choose a Data Source dialog, in Database, select SAP Hana.
• In the New Data Source dialog, specify the applicable connector properties.
• To test, select Test Connection.
• Select Ok to save your changes.

SAP HANA connector properties

Here are the properties for the SAP HANA connector:

Property	Control	Description
Data Source Name	text box	Enter the name of the data source
Username	text box	Enter the database username
Password	text box	Enter the database password
Connection Pool	text box	Enter the connection pool. The default is 30.
Connection String	text box	Enter the connection string for the SAP JDBC driver. The format is: jdbc:sap://<HOST>:<PORT>\<DB>
Connection Properties	text box	There are not currently any connection properties for the SAP HANA connector.

Create a schema with the Schema Wizard

Here are the steps to create an SAP HANA schema with the Schema Wizard:

• Sign in to the Incorta Direct Data Platform.
• In the Navigation bar, select Schema.
• In the Action bar, select + New → Schema Wizard.

• In (1) Choose a Source, specify the following:

  • For Enter a name, enter the schema name.
  • For Select a Datasource, select the SAP HANA external data source.
  • Optionally create a description.
• In the Schema Wizard footer, select Next.
• In (2) Manage Tables, in the Data Panel, first select the name of the Data Source, and then check the Select All checkbox.
• In the Schema Wizard footer, select Next.
• In (3) Finalize, in the Schema Wizard footer, select Create Schema.

Create a schema with the Schema Designer

Here are the steps to create an SAP HANA schema using the Schema Designer:

• Sign in to the Incorta Direct Data Platform.
• In the Navigation bar, select Schema.
• In the Action bar, select + New → Create Schema.
• In Name, specify the schema name, and select Save.
• In Start adding tables to your schema, select SQL Database.
• In the Data Source dialog, specify the SAP HANA table data source properties.
• Select Add.
• In the Table Editor, in the Table Summary section, enter the table name.
• To save your changes, select Done in the Action bar.

SAP HANA table data source properties

For a schema table in Incorta, you can define the following SAP HANA specific data source properties as follows:

Property	Control	Description
Type	drop down list	Default is SQL Database
Data Source	drop down list	Select the SAP HANA external data source
Incremental	toggle	Enable the incremental load configuration for the schema table. See the simple incremental load example configuration below.
Fetch Size	text box	Used for performance improvement, fetch size defines the number of records that will be retrieved from the database in each batch until all records are retrieved. The default is 5000.
Query	text box	Enter the SQL query to retrieve data from the SAP HANA database
Update Query	text box	Enable Incremental to configure this property. Enter the SQL query to retrieve data updates from the SAP HANA database.
Incremental Field Type	drop down list	Enable Incremental to configure this property. Select the format of the table date column: TImestamp Unix Epoch (seconds) Unix Epoch (milliseconds)
Callback	toggle	Turn this option on to enable the Callback URL field
Callback URL	text box	Enable Callback to configure this property. Specify the URL.

View the schema diagram with the Schema Diagram Viewer

Here are the steps to view the schema diagram using the Schema Diagram Viewer:

• Sign in to the Incorta Direct Data Platform.
• In the Navigation bar, select Schema.
• In the list of schemas, select the SAP HANA schema.
• In the Schema Designer, in the Action bar, select Diagram.

Load the schema

Here are the steps to perform a Full Load of the SAP HANA schema using the Schema Designer:

• Sign in to the Incorta Direct Data Platform.
• In the Navigation bar, select Schema.
• In the list of schemas, select the SAP HANA schema.
• In the Schema Designer, in the Action bar, select Load → Load Now → Full.
• To review the load status, in Last Load Status, select the date.

Explore the schema

With the full load of the SAP HANA schema complete, you can use the Analyzer to explore the schema, create your first insight, and save the insight to a new dashboard.

To open the Analyzer from the schema, follow these steps:

• In the Navigation bar, select Schema.
• In the Schema Manager, in the List view, select the SAP HANA schema.
• In the Schema Designer, in the Action bar, select Explore Data.

Additional Considerations

Below is a simple incremental load configuration example of how you would complete the related data source properties if you enable the Incremental property for the SAP HANA schema table.

Incremental Load Example

The Schema Designer is used to create a table for invoices, and is to be refreshed with invoice updates. In order to load the table incrementally with updates, the invoice table must contain a column of the type date or timestamp. The name of the date column is ModifiedOn, and the format of this column is Timestamp.

Here are the data source property values for this scenario:

• Incremental is enabled
• Query contains SELECT * FROM invoices
• Update containsSELECT * FROM invoices WHERE ModifiedOn > ?
• Incremental Field Type = Timestamp
