ErrorMode 
                This error variable determines what action is to be taken by Qlik Sense when an error is encountered during script execution.
Syntax:
ErrorMode
Arguments:
| Argument | Description | 
|---|---|
| ErrorMode=1 | The default setting. The script execution will halt and the user will be prompted for action (non-batch mode). | 
| ErrorMode =0 | Qlik Sense will simply ignore the failure and continue script execution at the next script statement. | 
| ErrorMode =2 | 
                                 Qlik Sense will trigger an "Execution of script failed..." error message immediately on failure, without prompting the user for action beforehand.  | 
                        
Example:
set ErrorMode=0;
