 @GS@  200   Training & Quality Client

6. To locate the icon code: tcode BIBS --> Element --> Icon Overview
You may also output icons at the beginning of lines by using an icon  code (for example, @1D@ for the STOP icon). You can get a list of icon  codes from Report RSTXICON. Pay attention to the codes with two '@'  symbols displayed by the report. You cannot include text symbols. The  'include indicator' cannot be used for this function. SUBHINT here.  These can be used on system messages as well.
