When you create or edit a derived field, you use the derived field interface.

1
Selector
You use the selector area to select and drag and drop your function, function template, schema field, or standard field on to the rule builder.
Use the drop-down to select between:
Function Functions - lists available functions,
Function template icon Function templates - lists available function templates,
Schema field icon Schema fields - lists fields available from dataset categories (event, profile, lookup) and previously defined derived fields, and
Standard field icon Standard fields - standard available fields (like Platform Dataset ID). Only string and numeric standard fields are displayed in the selector. If the function supports other data types, standard fields with these other data types can be selected for values or fields within the rule interface.
You can search for function, function templates, schema, and standard fields using the Search icon Search box.
You can filter the selected object list by selecting Filter icon Filter and specify filters in the Filter fields by dialog. You can easily remove filters using Close icon for each filter.

Rule builder
You build your derived field sequentially using one or more rules. A rule is a specific implementation of a function and is therefore always associated with only one function. You create a rule by dragging and dropping a function into the rule builder. The function type determines the interface of the rule.
See the Rule interface for more information.
You can insert a function at the start, end, or in between rules already available in the rule builder. The last rule in the rule builder determines the final output of the derived field.
