About Advanced Mapping

By default, the expression editor for the Calculate, ForEach, While, and Decision/Branch steps provides a list of standard choices that make sense for typical data flow. In more advanced use cases, you might want the expression editor to display a list of all available choices.

To display a complete list, select the Advanced mapping checkbox on the Options tab of any of these steps. For each expression, the list will display additional choices as shown below:

• Target expression in the Calculate step: Workflow inputs and step outputs
• Source expression in the Calculate and ForEach steps: Step inputs and workflow outputs
• Rule expression in the Decision/Branch and While steps: Step inputs and workflow outputs

Use these choices with caution, as they may lead to unpredictable results.
