SAP CATT has a new interface from Release 4.5a for using test procedures in the format of external test tools in the SAP System.
You can save and run test procedures of external test tools in the SAP System as external CATT test modules.
The test procedures are maintained by running the external test tool in the SAP System maintenance dialog.
Customizing settings in the application component CA-CAT-TOL are required for using the external test tool in the SAP System from Release 4.5a.
