Set up SAP ECC

This guide explains how to create a dedicated service user in SAP ECC and grant the necessary permissions for Atlan to extract metadata.

Prerequisites

Before you begin, make sure you have:

• Administrative access to SAP ECC.
• SAP system details, including:
  • Host
  • System number
  • Client number

Create communication user for metadata extraction

1. In the SAP GUI command field, enter SU01 and press Enter to open User Maintenance.
2. In the User field, enter a name for the new service user and click Create.
3. On the Address tab, provide the required contact information.
4. Open the Logon Data tab and:
   • Set an initial password (enter it twice).
   • Set User Type to C (Communications Data).
5. Switch to the Roles tab and assign roles that enable:
   • Remote function call (RFC) execution
   • Table-level read access for metadata tables
   • Access to system-level information
6. Verify that the assigned roles enable execution of these RFC modules:
   • STFC_CONNECTION: Verifies connectivity between Atlan and SAP ECC.
   • RFC_SYSTEM_INFO: Retrieves system metadata such as SYSID, operating system, and release version.
   • RFC_READ_TABLE: Enables table-level reads for metadata extraction.
7. Click Save to confirm the changes.

note

The user must change the password on first login.
