2. Available Data Masking: Define which data masking options are available when creating tasks
3. Batch Size: Specify the maximum number of lines to be extracted from the SAP system per request (Standard: 15.000)
4. Dynamic batch size: attempts to optimise the row extraction based on the batch size and column selection of the table
5. Limit dependency batch size: If your SAP system uses MaxDB and you are experiencing problems with data extraction, you can activate this option
6. Test download table (optional): Here you can enter a table that will be used to perform the connection test (Standard: T000, Fallback: T001)

1. General / Permissions: Switch between the tabs for the login details and the permissions for who can use this connection later

1. Test Connection (The connection to the SAP system can also be saved without a connection test)

• Test whether dab Nexus can access your SAP system with the stored settings
• A success message or error message will appear

1. Create or Create & Close: Once all settings have been saved, the connection data for the SAP system can be saved. Click Create & Close to save the connection data, automatically exit the view and return to the list of saved SAP systems.

Once the SAP connection has been successfully created, you will receive a success message and the new connection will now be available in a table format together with all your other SAP connections. The following details are displayed:

• Name of the connection to the SAP system, SID, Server, Instance number, Client, Status (Unknown, Connected, Failed), Registration Status and Last test.

• Three dots next to the connection name: here you can test, register, change, copy, delete the connection and view a change history.

• Indicator, whether the SAP system is registered or not:
  • Grey or Not registered: SAP system isn't registered
  • Black or Registered: SAP system is registered (the option Register in the submenu is now grey)
