# SAP System Connections

Teamscale connects to an SAP NetWeaver® AS ABAP® system through an *SAP ABAP System Connection*.
To add one, go to *Admin* > *Settings* > *SAP* > *SAP ABAP System Connection* and click `Add`.
Every SAP system needs its own connection, identified by a unique connection ID — the three-letter SAP system ID is a good choice.

:::tip How to Set Up an SAP System Connection
For step-by-step instructions, see our [how-to guide](../../../howto/sap-integration/teamscale-sap-connection/).

## System and Logon Parameters

Which parameters are required depends on the connection type, that is, whether the connection is direct or uses logon balancing.

## Object Selection Parameters

These options control which code Teamscale retrieves, how often it is updated, and whether other result data such as test coverage is included.

## Code Inspector Execution

These options control the execution of SAP Code Inspector during code retrieval.
They require a Code Inspector variant to exist in the SAP system.

The name of the executed Code Inspector variant must be specified in parameter *Code Inspector: variant name*.
If this is not a public variant, but a user variant, the SAP username of the owner must be additionally specified in *Code Inspector: variant user*.

## Check Descriptions

Available from Teamscale 2026.5 and Teamscale Connector for SAP NetWeaver® AS ABAP v2606.

## Secure Network Communications (SNC)

SNC encrypts the RFC communication between Teamscale and SAP NetWeaver.
Both the SAP system and the Teamscale server have to be prepared before these options take effect.

## Global Settings

These options apply to all SAP connections and are found under *SAP* > *SAP ABAP System Connections - Global Settings*.

## JVM Properties

A few aspects are configured on the Teamscale server rather than in the web interface.

See [Configuration on the Teamscale Server](../../../howto/sap-integration/teamscale-server/) for how to set these.
