Errors can be handled at three levels: individual actions, groups of actions, or project level.
Individual actions
Set the "Timing Properties.
Groups of actions
For localized error handling, use the Try, Catch, Finally and End actions in the Flow Control category. The valid combinations are Try-Catch-End, Try-Finally-End or Try-Catch-Finally-End. To use these actions you must place the actions you want to run as child actions of the try, catch or finally.
Localised error handling works as follows:
1. Child actions of the TRY are executed
...
5. The END action signifies the end of the exception handling block
Project level error handling
Every project contains an OnFailure action list Target which is executed if any action in the Main action list Target fails and it isn't handled by a Try-Catch block.
By default, if an action fails it will abort running the Main action listTarget, and run any actions in the OnFailure action listTarget. If you want to ignore an error for a particular action and continue processing, then set the Ignore Error property of the action.
