Collection Actions for Flow (Sort, Filter, Find, Join, Map, and more)

This package contains new Flow actions that are designed to manipulate any SObject or collection of SObjects. This means that in one Flow you might use them with a collection of Accounts and in another flow a collection of Leads.

Add or Insert Record

Takes as input a collection of records and a single record, and an optional index value. Returns the combined collection. If the index value is specified and is less than the length of the inputCollection, the

Inputs

List<SObject> inputCollection;

SObject inputRecord

Integer index

Outputs

List<SObject> outputCollection;

Copy Collection

Takes as input a collection of records and returns the collection as output, allowing a new variable or reference to have the same value

Inputs

List<SObject> inputCollection;

Outputs

List<SObject> outputCollection;

Count Records And Fields

Takes a collection of records and returns a count. Optionally also takes a field name and a field value, and then also counts the number of records that have that particular value for that particular field. Returns both the number of matches and the total number of records. Added in V

Inputs

List<SObject> inputCollection;

String fieldName;

String fieldValue;

Outputs

Integer totalNumber

Integer matchedNumber

String errors

Extract Strings From Collection

takes a collection and a field name, and returns a list of strings reflecting the values of those fields for the records. For example, if you pass in a list of Contacts and a fieldName of “Id”, you’ll get back a list of recordIds for the contacts.

Inputs

List<SObject> inputCollection;

String fieldName;

Output

List<String> stringList

Filter Collection

Filters a collection against a formula string which can be created by an included Expression Builder Flow Screen Component.

Inputs

List<SObject> inputCollection;

String formula;

Outputs

String errors;
List<SObject> outputCollection;

Details

For each member of the inputCollection, this action will evaluate the provided formula and add the member to the outputCollection if the formula is true.

The formula must be a string that can be processed by the Salesforce formula engine. The actual engine that evaluates this string is written in Apex and is included in the Collection Processors package.

It will use the recordId of the current member as context, replacing expressions in the formula string of the form $Record.fieldname. For example, if the formula is ‘$Record.Age__c > 21’ and the input Collection is a collection of Student__c, the evaluator will do the following:

Loop through the collection of Student records. For each record:

1. use its ID and retrieve the record
2. retrieve the values of any fields present in the formula string
3. use the formula evaluator to evaluate the formula
4. If the formula evaluates to true, add the current record to the output collection

Find Record in Collection

Returns all records from the inputCollection that have a field with name targetField that has a value of targetValue. Pass in the name of the object in targetObject (for example, if the inputCollection is a List of Contacts, set targetObject to Contact. There’s probably a way to determine this automatically but it’s not implemented in the action at this time). If there’s just a single result, the result is returned as singleOutputMember. Otherwise it’s returned as multipleOutputMembers.

Inputs

List<SObject> inputCollection;

String targetObject

String targetField

String targetValue

Outputs

SObject singleOutputMember;

List<SObject> multipleOutputMembers

Generate Collection Report

Given a collection and a comma-separated list of field names, generates a string that includes all of the field values for every member of the collection. Not particularly pretty, but useful for debugging and a good building block to show what can be done by doing string manipulations on collections.

Inputs

List<SObject> inputCollection;

String shownFields

Outputs

String reportString

Get Child Collection

Takes a record and returns a specified collection of child records related to the input record.

Pass in either a record or a recordID (as a string), but not both. Specify the childRelationshipName, which should be the name of the child Object. Example. If you have an Opportunity and want to retrieve all of the OpportunityContactRoles associated with the input, specify a childRelationshipName of OpportunityContactRole. Note that this should also be specified as the Output Collection.

In childRecordFieldsCSV, specify the fields you want returned as a comma-delimited string. Example: Id,Name

Inputs

SObject inputRecord;
String inputRecordId;
String childRelationshipName;
String childRecordFieldsCSV;

Outputs

List<SObject> childCollection;
String errorText;

Get Lookup Collection

Takes a collection of records and the name of an object related via a Lookup, and returns a collection of objects.

Pass in either a collection of records or a collection of string record ID’s. Pass in the name of the related object. Example: You start with a collection of OpportunityContactRoles and you want to get the Contacts associated with your OpportunityContactRoles via the ContactId Lookup field. In this case you would set lookupObjectName to Contact.

In lookupRecordFieldsCSV, specify the fields you want returned as a comma-delimited string. Example: Id,Name

For more information, see https://unofficialsf.com/automate-junction-updates-with-getchildcollection-and-getlookupcollection/

Inputs

List<SObject> inputCollection;
List<String> inputIds;
String lookupRecordFieldsCSV;
String lookupObjectName;

Outputs

List<SObject> lookupCollection;
String errorText;

Get First

Returns the first member of the inputCollection. The inputCollection is not modified by this action. Make sure that the types of your inputCollection and outputMember match.

Inputs

List<SObject> inputCollection;

Outputs

SObject outputMember;

Join Collections

Takes two collections (of the same type, please!) and returns their union as a single collection.

Inputs

List<SObject> inputCollection1;

List<SObject> inputCollection2;

Outputs

List<SObject> outputCollection;

Map Collection

Takes a collection and a set of key value pairs. Example:

Rating : Warm, Industry : Banking

Goes through the collection and changes each field with a name matching the key to the specified value.

Inputs

List<SObject> inputCollection;

String keyValuePairs;

Outputs

List<SObject> outputCollection;

String errors;

Remove Record from Collection

Takes a collection and an index integer. Uses the Apex List class remove method to remove the member of the collection at the index location.

Inputs

List<SObject> inputCollection;

Integer index;

Outputs

List<SObject> outputCollection;

Sort Collection

Takes a collection and a sortKeys string formatted as key value pairs (example:

{“sortkeys”: [
{“field”:”Name”,
“direction”:”asc”} ]}

Inputs

List<SObject> inputCollection;

String sortKeys;

Outputs

List<SObject> outputCollection;
