relatedListRecord

Retrieves data of a child record of a specified parent record and stores the result into the variable context as a Data item.

Highly similar to relatedList, but only retrieves one child record.

Attributes

var
Required	Value type	EL-evaluated
Yes	String	No
Name of the variable that holds the Data item.

type
Required	Value type	EL-evaluated
Yes	String	Yes
The resolved value of this attribute should be the API name ofthe child record's object type.

parentID
Required	Value type	EL-evaluated
Yes	String	Yes
Defines the ID of the parent record.

parentType
Required	Value type	EL-evaluated
Yes	String	Yes
The resolved value of this attribute should be the API name ofthe parent record's object type.

fields

Required

Value type

EL-evaluated

Yes

String

Yes

Defines the fields whose values are retrieved. The resolved String should be a comma-separated list of the fields' API names, eg. "Id, Name,Quantity".

If the resolved set of fields contains names of fields that don't exist or otherwise cannot be retrieved, the command will still succeed but the Data item will not contain entries for the "invalid" fields. A warning listing these "invalid" fields is also produced.

where
Required	Value type	EL-evaluated
Yes	String	Yes
This attribute defines the filtering conditions to limit the amount of results, preferably to a single record. The resolved String should specify one or more condition expressions in SOQLCondition Expression Syntax.

Examples

The relatedListRecord command can be used to retrieve a child record whose ID you don't know (as then you could just use record). The where attribute should be set to a SOQL condition expression that limits the possible results to a single record, as otherwise it is uncertain which record the command retrieves. One common example is the retrieval of an Opportunity's primary contact:

CODE

<relatedListRecord var="PrimaryContactRole"fields="Contact.Name, Contact.Email"parentID="${opp.id}"parentType="Opportunity"type="OpportunityContactRole"where="IsPrimary = true" />

This works well as the "IsPrimary" field can only be "true" for one OpportunityContactRole record linked to a particular Opportunity.
