Derived fields

Derived fields are an important aspect of the real-time reporting functionality in Adobe Customer Journey Analytics. A derived field allows you to define (often complex) data manipulations on the fly, through a customizable rule builder. You can then use that derived field as a component (metric or dimension) in Workspace or even further define the derived field as a component in Data view.

Derived fields can save a significant amount of time and effort, compared to transforming or manipulating your data in other locations outside of Customer Journey Analytics. Such as Data Prep, Data Distiller, or within your own Extract Transform Load (ETL) / Extract Load Transform (ELT) processes.

Derived fields are defined within Data views, are based on a set of functions defined as rules, and applied to available standard and/or schema fields.

Example use cases are:

  • Define a derived Page Name field that corrects improper collected page name values to correct page name values.

  • Define a derived Marketing Channel field that determines the proper marketing channel based on one or more conditions (for example URL parameter, page URL, page name).

Derived field interface

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

Screenshot of the Derived field dialog

Name
Description
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.
2
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.
3
Field Settings
You can name and describe your derived field and inspect its field type.
4
Final Output
This area shows an on-the-fly updated preview of output values, based on data over the last 30 days and the changes you make to the derived field in the rule builder.

Field template wizard

When you access the derived field interface for the first time, the Start with a field template wizard is shown.

  1. Select the template that best describes the type of field you are trying to create.
  2. Select the Select button to continue.

Your derived field dialog is populated with rules (and functions) required or useful for the type of field that you selected. See Function templates for more information on the available templates.

Rule interface

When you define a rule in the rule builder, you use the rule interface.

Screenshot of the Derived Field Rule Interface

Name
Description
A
Rule Name
By default the rule name is Rule X (X referring to a sequence number). To edit the name of a rule, select its name and type in the new name, for example Query Parameter.
B
Function Name
The selected function name for the rule, for example URL PARSE. When the function is the last in the sequence of functions and determines the final output values, the function name is followed by - FINAL OUTPUT, for example URL PARSE - FINAL OUTPUT.
To show a popup with more information on the function, select Help icon .
C
Rule Description
You can optionally add a description to a rule.
Select More icon , then select Add Description to add a description or Edit Description to edit an existing description.
Use the editor to enter a description. You can use the toolbar to format the text (using style selector, bold, italic, underline, right, left, centered, color, number list, bullet list) and adding links to external information.
To finish editing the description, click outside of the editor.
D
Function Area
Defines the logic of the function. The interface depends on the type of function. The dropdown for Field or Value shows all categories of fields (rules, standard fields, fields) available, based on the type of input the function expects. Alternatively, you can drag and drop a field from the Schema and Standard fields selector on to a Field or Value. When that dragged field is originating from a Lookup dataset, a Lookup function is automatically inserted before the function you define.
See Function reference on detailed information for each of the functions supported.

NOTE
Derived fields are managed at a Connection level in Customer Journey Analytics. Any change made to a derived field in any of the Data views associated with that Connection applies across all these associated Data views.

Function templates

To quickly create a derived field for specific use cases, function templates are available. These function templates can be accessed from the selector area in the derived field interface or are presented upon first use in the Start with a field template wizard.

Marketing channels

This template is configured to use the Url Parse and Case When functions multiple times to get appropriate values from a URL. Logic is then applied on these values to associate the URL to a specific marketing channel.

Details

To use the template, you have to specify the correct parameters for each function listed as part of the rules in the template. See Function reference for more information.

You want to define rules to identify various marketing channels, by applying cascading logic to set a marketing channel field to the proper value:

  • If the referrer is from a search engine and the page has a query string value where cid contains ps_, the marketing channel should be identified as a Paid Search.
  • If the referrer is from a search engine and the page does not have the query string cid, the marketing channel should be identified as a Natural Search.
  • If a page has a query string value where cid contains em_, the marketing channel should be identified as an Email.
  • If a page has a query string value where cid contains ds_, the marketing channel should be identified as a Display Ad.
  • If a page has a query string value where cid contains so_, the marketing channel should be identified as a Paid Social.
  • If the referrer is from a referring domain of twitter.com, facebook.com, linkedin.com, or tiktok.com, the marketing channel should be identified as a Natural Social.
  • If none of the above rules are matched, then the marketing channel should be identified as Other Referrer.

In case your site receives the following sample events, containing Referrer and Page URL, these events should be identified as follows:

Customer Journey Analytics uses a nested container structure, modeled after Adobe Experience Platform’s XDM (Experience Data Model). See Containers and Filter containers for more background information. This container model, albeit flexible by nature, imposes some constraints when using the rule builder.

Customer Journey Analytics uses the following default container model:

The following constraints apply and are enforced when selecting and setting values.

Derived field lookup-uc-derivedfield

You define an Activity Name derived field. You use the LOOKUP function to define a rule to lookup the value from your collected data, specified in the Field to apply lookup field (for example ActivityIdentifier). You select the lookup dataset from the Lookup dataset list (for example New CJA4T Activities). Then you selecting the identifier field (for example ActivityIdentifier) from the Matching key list and the field to return from the Values to return list (for example ActivityName).

More info

You can quickly insert a Lookup function in the rule builder, already containing one or more other functions.

  1. Select Schema fields from selector.
  2. Select Schema field icon Lookup datasets.
  3. Select your lookup dataset and find the field you want to use for lookup.
  4. Drag and drop the lookup field on any of the available input fields for a function (for example Case When). When valid, a blue box, labeled + Add, allows you to drop the field and automatically insert a Lookup function before the function you dropped the lookup field on. The inserted Lookup function is automatically populated with relevant values for all fields.

The following limitations apply to the Derived field functionality in general:

  • You can use a maximum of ten different schema fields (not including standard fields) when defining rules for a derived field.
    • From this maximum of ten different schema fields, only a maximum of three lookup schema or profile schema fields are allowed.
  • You can have a maximum of 100 derived fields per Customer Journey Analytics connection.

As an example, the condition below uses 13 operators.

Sample operators

More information

Trim and Lowercase are features already available in the component settings in Data views. Using Derived Fields allows you to combine these functions to do more complex data transformation directly in Customer Journey Analytics. For example, you can use Lowercase to remove case sensitivity in an event field, and then use Lookup to match the new lowercase field to a lookup dataset that only has lookup keys in lowercase. Or you can use Trim to remove characters before setting up Lookup on the new field.

Support for lookup and profile fields in Derived Fields enables you to transform data based on event lookups and profile attributes. This can be especially helpful in B2B scenarios with account-level data in lookup or profile datasets. Additionally, this support is useful to manipulate data in common fields from lookup data (like campaign info and offer type), or from profile data (like member tier and account type).
