The Mapping dashboard is used to create mappings between two units on the Pipeline dashboard. You use this dashboard to map one or more attributes of a unit with parameters on a second unit. Based on requirements, these parameters can be body, path, query, header or cookie parameters.
Attributes are non-editable name / value pairs in the source unit, whereas parameters are editable name / formula pairs in the target unit.
After clicking on a unit in the Pipeline dashboard, the Mapping dashboard appears. Here you map attributes from a source unit to parameters on the target unit (the unit you opened).
Hovering over the value of a parameter, a summary of the source for the value is shown.
Clicking Edit Formula from the summary dialog opens the Formula editor.
Using the Formula editor, you generate a value for the parameter. You can create very basic to quite complex formulas in the Formula editor using combinations of References, Axel-f Functions and Operators.
