Using SETTAB and RESTAB (SAP Library - CATT: Enhanced Mode (BC-CAT-TOL))

Using SETTAB and RESTAB

Caution

If customizing standard settings are changed, they must be reset in the same test.

CATT requires a fully installed system (e.g. periods must be open). Customizing tables should therefore only be set in exceptional cases.

Rules for using SETTAB:

Only use the function when table setting differences, or errors caused by particular settings, are to be tested.

CATT automatically resets a SETTAB at the end of a test. If you want to prevent this, call RESTAB% in the test case. The system then keeps all changes made using SETTAB, even after the test is finished.

If a CATT test terminates because of the termination flag, RESTAB is automatically called for this test.

Some errors cause the main CATT transaction to crash:

the user enters /N in the OK code when the transaction is running in the foreground.
a transaction contains the ABAP command LEAVE TO TRANSACTION...
a session terminates unexpectedly.
more than 36 different function modules are called in one run by the CATT function FUN.
a run-time error occurs in a function module which was called by FUN.

CATT cannot call RESTAB itself in these cases. Choose Utilities ® Call RESTAB in the CATT initial screen.
