How to solve the Time Zone Definition Problems?

The Time zone is defined in table TTZCU for System wide and Client wide.

If you want it for individual user, go to SU01 under the default Personal Time zone sections.

Settings for individual users is done when you have global users in different time zone.

For Local users only, go to SM30 and change the table TTZCU. e.g. UTC+8

This is done when your Spool time is incorrect.
