When scanning SAP HANA source, Microsoft Purview supports extracting technical metadata including:

  • Server
  • Databases
  • Schemas
  • Tables including the columns, foreign keys, indexes, and unique constraints
  • Views including the columns. Note SAP HANA Calculation Views are not supported now.
  • Stored procedures including the parameter dataset and result set
  • Functions including the parameter dataset
  • Sequences
  • Synonyms

When setting up scan, you can choose to scan an entire SAP HANA database, or scope the scan to a subset of schemas matching the given name(s) or name pattern(s).

Known limitations

When object is deleted from the data source, currently the subsequent scan won't automatically remove the corresponding asset in Microsoft Purview.

Prerequisites

Required permissions for scan

Microsoft Purview supports basic authentication (username and password) for scanning SAP HANA.

The SAP HANA user you specified must have the permission to select metadata of the schemas you want to import.

CREATE USER <user> PASSWORD <password> NO FORCE_FIRST_PASSWORD_CHANGE;
GRANT SELECT METADATA ON SCHEMA <schema1> TO <user>;
GRANT SELECT METADATA ON SCHEMA <schema2> TO <user>;

And the user must have the permission to select on system table _SYS_REPO.ACTIVE_OBJECT and on system schemas _SYS_BI and _SYS_BIC.

GRANT SELECT ON _SYS_REPO.ACTIVE_OBJECT TO <user>;
GRANT SELECT ON SCHEMA _SYS_BI TO <user>;
GRANT SELECT ON SCHEMA _SYS_BIC TO <user>;

Register

This section describes how to register an SAP HANA in Microsoft Purview by using the Microsoft Purview governance portal.

  1. Open the Microsoft Purview governance portal by:

  2. Select Data Map on the left pane.

  3. Select Register.

  4. In Register sources, select SAP HANA > Continue.

  5. On the Register sources (SAP HANA) screen, do the following:

    1. For Name, enter a name that Microsoft Purview will list as the data source.

    2. For Server, enter the host name or IP address used to connect to an SAP HANA source. For example, MyDatabaseServer.com or 192.169.1.2.

    3. For Port, enter the port number used to connect to the database server (39013 by default for SAP HANA).

    4. Select a collection from the list.

  6. Select Finish.

Scan

Use the following steps to scan SAP HANA databases to automatically identify assets. For more information about scanning in general, see Scans and ingestion in Microsoft Purview.

Authentication for a scan

The supported authentication type for an SAP HANA source is Basic authentication.

Create and run scan

  1. In the Management Center, select integration runtimes. Make sure that a self-hosted integration runtime is set up. If it isn't set up, use the steps in in prerequisites.

  2. Go to Sources.

  3. Select the registered SAP HANA source.

  4. Select + New scan.

  5. Provide the following details:

    1. Name: Enter a name for the scan.

    2. Connect via integration runtime: Select the configured self-hosted integration runtime.

    3. Credential: Select the credential to connect to your data source. Make sure to:

      • Select Basic Authentication while creating a credential.
      • Provide the user name used to connect to the database server in the User name input field.
      • Store the user password used to connect to the database server in the secret key.

      For more information, see Credentials for source authentication in Microsoft Purview.

    4. Database: Specify the name of the database instance to import.

    5. Schema: List subset of schemas to import expressed as a semicolon separated list. For example, schema1; schema2. All user schemas are imported if that list is empty. All system schemas and objects are ignored by default.

      Acceptable schema name patterns that use SQL LIKE expression syntax include the percent sign (%). For example, A%; %B; %C%; D means:

      • Start with A or
      • End with B or
      • Contain C or
      • Equal D

      Usage of NOT and special characters aren't acceptable.

    6. Driver location: Specify the path to the JDBC driver location in your machine where self-host integration runtime is running. For example: D:\Drivers\SAPHANA.

      1. For self-hosted integration runtime on a local machine: D:\Drivers\SAPHANA. It's the path to valid JAR folder location. The value must be a valid absolute file path and doesn't contain space. Make sure the driver is accessible by the self-hosted integration runtime;; learn more from prerequisites section.
      2. For Kubernetes-supported self-hosted integration runtime: ./drivers/SAPHANA. It's the path to valid JAR folder location. The value must be a valid relative file path. Please refer to the documentation to set up a scan with external drivers for uploading drivers in advance.

    7. Maximum memory available: Maximum memory (in gigabytes) available on the customer's machine for the scanning processes to use. This value is dependent on the size of SAP HANA database to be scanned.

    Screenshot that shows boxes for scan details.

  6. Select Continue.

  7. For Scan trigger, choose whether to set up a schedule or run the scan once.

  8. Review your scan and select Save and Run.

View your scans and scan runs

To view existing scans:

  1. Go to the Microsoft Purview portal. On the left pane, select Data map.
  2. Select the data source. You can view a list of existing scans on that data source under Recent scans, or you can view all scans on the Scans tab.
  3. Select the scan that has results you want to view. The pane shows you all the previous scan runs, along with the status and metrics for each scan run.
  4. Select the run ID to check the scan run details.

Manage your scans

To edit, cancel, or delete a scan:

  1. Go to the Microsoft Purview portal. On the left pane, select Data Map.

  2. Select the data source. You can view a list of existing scans on that data source under Recent scans, or you can view all scans on the Scans tab.

  3. Select the scan that you want to manage. You can then:

    • Edit the scan by selecting Edit scan.
    • Cancel an in-progress scan by selecting Cancel scan run.
    • Delete your scan by selecting Delete scan.

Note

  • Deleting your scan does not delete catalog assets created from previous scans.
