To define an SMS data set under TSO/E you do not need APF authorization, but it is recommended because APF authorization reduces path length.

For the DEFINE and IMPORT commands, you can establish this authorization by adding the DEFINE and IMPORT command processor names to the installation access list APFCTABL in CSECT IKJEFTE2, or the parameter AUTHCMD NAMES in SYS1.PARMLIB member IKJTSO00. For a call of access method services, you can establish this authorization by adding IDCAMS to the installation access list APFPTABL in CSECT IKJEFTE8 or the parameter AUTHPGM NAMES in SYS1.PARMLIB member IKJTSO00. For more information about specifying authorized commands and programs under TSO/E, see z/OS TSO/E Customization.

To define or import an SMS data set while under option 6 of ISPF/PDF, you must include the DEFINE and IMPORT processor names in the command table in ISPTCM. See z/OS ISPF Planning and Customizing for more information.
