base_tmp_dsn

This option allows you to overwrite default base_tmp_dsn set outside of the environment. If you want to set this prefix of temporary dataset names for various activities then you can put this option into the environment. It is also possible to set at the task level as is clear from the samples below.

You can use HWM variables and %SYSUID. (which is replaced with the current user name).
