As well as the CATT-independent system variables, you can also use special variables.
Special variables can be included directly in a character string (literal).
You cannot use variable offset and length as usual, e.g. &M01+02(08).
This is the same value as the contents of the system variable SY-MANDT.
The date is in &DAT (see date variables) in external format, without format characters. You define which external format is effective, as a default value in the user master record.
In contrast to &DAT, SY-DATUM is always in the internal format: YYYYMMDD
This is the same value as the contents of the system variable SY-UNAME.
The current RFC target system on which a remote test is running.

&JHR current year-
&JHV previous year-
&JHN next yearAn immediately following entry +nn or -nn increases or decreases the year by nn.
The variable &LPC contains the current value of the innermost loop count in DO/ENDDO loops.

The special variables must be specified in upper-case letters.
