After entering all connection details, the following actions can be performed:
Click Validate to verify the connection.
Click Save to store the connection for future use.
Click Save & Configure to apply additional settings before saving.
The saved connection will appear on the Connectors home page.
For detailed information about SAP connection methods, authorization requirements, RFC implementation, and RFC queries, refer to SAP Table Connector – Connectivity and RFC Reference.
Connector Settings
Once the connection is validated successfully, various settings are provided to retrieve and display the information from the data source. The connection settings include Crawler, Profiler, Query Policies, Access Instruction, Business Glossary Settings, and Others.
Crawler
Crawler settings are configured to connect to a data source and collect and catalog all the data elements in the form of metadata.
Profiler
Profiling is the process of gathering statistics and informative summaries about the connected data source(s). Statistics can help assess the data source's quality before using it in an analysis. Profiling is always optional; crawling can be run without profiling.
Query Policies
The Query Policies in the Crawler setting provide the right access to the Query sheet functions (Join, Union, SUM, or aggregate functions). You can specify the desired roles and permission to deny the usage of the query sheet function. A role that has been denied policy permission will not have access to those functions in the Query Sheet.
Example: If the user selects the Role as “OE_HRADMIN,” Query Type as “JOIN,” and the Access Type as “DENY,” then the users associated with the OE_HRADMIN privileges are restricted from using the JOIN function in the Query Sheet page.
Access Instruction
It allows the data owner to instruct others on using the objects in the application.
Business Glossary Settings
The Business Glossary setting provides flexibility and control over how they view and manage term association within the context of a business glossary at the connector level.
Others
The Enable/Disable Metadata Change Notifications option sets the change notification about metadata changes of the data objects.
Users can use the toggle button to set the Default Governance Roles (Steward, Owner Custodian, etc.)
Using the Roles and Teams, users can select the role and team to receive the notification of metadata changes.
Crawling a Table
Navigate to the Connectors page and click Crawl/Profile.
A search field will be displayed, where you can search for specific tables by entering 3 characters followed by %, and based on this, all the matched tables will be displayed.
Select Crawl, Profile, Unprofiled, or Scheduled based on the requirement.
Click on Run to gather all metadata from the connected source into the Data Catalog.
