Specifications casewhen-io

Use case 1 casewhen-uc1

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:

Data before casewhen-uc1-databefore

Derived field casewhen-uc1-derivedfield

You define a new Marketing Channel derived field. You use the CASE WHEN functions to define rules that create values for the based on existing values for both the Page URL and Referring URL field.

More information

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:

{width="50%"}

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

table 0-row-2 1-row-2 2-row-2 3-row-2 1-align-center 4-align-center 7-align-center 10-align-center layout-auto
	Constraints
A	Values you select within the same If, Else If construct (using And or Or) in a rule must originate from the same container and can be of any type (string , numeric , and so forth).
B	All the values you set across a rule must be from the same container and have the same type or a derived value of the same type.
C	The values you select across If, Else If constructs in the rule do not have to originate from the same container and do not have to be of the same type.

• The user determines to use the delimiter ‘-’ between the values.

Imagine the following bookings occur:

• Customer ABC123 books a flight between Salt Lake City (SLC) and Orlando (MCO)
• Customer ABC456 books a flight between Salt Lake City (SLC) and Los Angeles (LAX)
• Customer ABC789 books a flight between Salt Lake City (SLC) and Seattle (SEA)

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 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.
