Qlikview has a help file where you can find such information. Honestly, I kid you not.

Start Qlikview and press the F1 key to open the help file.

Trace

The trace statement writes a string to the Script Execution Progress window and to the script log file, when used.

It is very useful for debugging purposes. Using $-expansions of variables that are calculated prior to the Trace statement, you can customize the message.

The syntax is:

trace string

Examples:

trace Main table loaded;

Let MyMessage = NoOfRows('MainTable') & ' rows in Main Table';

trace $(MyMessage);

Back to Script Statements and Keywords.
