What does the Trace function provide during script execution?

The Trace function in Qlik Sense serves a vital purpose during script execution by allowing developers to log custom messages. This function enables users to insert specific strings into the script's execution log, which can be particularly useful for tracking the flow of execution and debugging. By providing real-time feedback on the script's processing, developers can gain insights into where the execution may be encountering issues and understand the context around those operations.

This custom string acts as a marker or note that can clarify the state or values of certain variables, the status of script execution, or any other relevant information a developer chooses to document. Thus, the use of Trace is an invaluable tool for monitoring and troubleshooting scripts in Qlik Sense, enhancing the overall quality and efficiency of data architecture development.

Other options, while relevant to various aspects of script execution and debugging, do not accurately reflect the primary function of the Trace command. The function is not designed to output current field values, success rates of scripts, or to summarize script variables—those would require different functions or methods within Qlik Sense’s scripting language.
