Q6. What are Flow Resources?

Flow Resources represent values that you can reference throughout the flow. Some resources, such as global constants and global variables, are provided by the system. Other resources are created when you add an element to a flow. Some of the Flow Resources are listed in the table below.

ResourceDescription
ActionsOutput values that are stored automatically from Action elements.
ChoiceCreate a choice option to use in a screen component, such as a Radio Buttons or Multi-Select Picklist component.
ConstantStore a fixed value that you can use throughout a flow.
Decision OutcomeWhen you add a Decision element to a flow, its outcomes are available as Boolean resources.
FormulaCalculate a value when the formula is used in the flow.
Global ConstantFixed, system-provided values, such as EmptyStringTrue, and False.
Global VariableSystem-provided variables that reference information about the Salesforce org or running user, such as the user’s ID or the API session ID.
Pause ConfigurationWhen you add a Pause element to a flow, its configurations are available as Boolean resources.
Picklist Choice SetGenerate a set of choices by using the values of a picklist or multi-select picklist field.
Picklist ValuesSystem-provided values for picklist fields in record variables and record collection variables.

Q7. What are the key Building Blocks of Flows?

Key Building Blocks of Flows are:

  1. Elements – represents an action that the flow can execute. Examples: display information or collect data from flow users, executing.
  2. Connectors – defines an available path that the flow can take at run time.
  3. Resources – represents a value that you can reference throughout the flow.

Q8. Explain Running User Context of a Flow.

Flows run in user context or system context. For a flow running in user context, the running user’s profile and permission sets determine the object permissions and field-level access of the flow. A flow that runs in system context has permission to access and modify all data.

Q9. What is a Flow Interview?

A Flow Interview is a running instance of a flow. When you run a flow interview, whether through a link, button, or tab, you’re running a single instance of a flow.

  • Pause a Flow Interview – If your administrator has configured a given flow to do so, you can pause its interviews
  • Resume a Flow Interview – If you paused a flow interview, resume it after you have all the necessary information
  • Delete a Flow Interview – If you paused a flow interview and don’t plan to resume it, delete it. By removing unnecessary interviews, you make sure that your pending list includes only interviews that you still plan to act on

Q10. Explain Transaction with respect to Flows.

A transaction represents a set of operations that are executed as a single unit. Each flow interview runs in the context of a transaction. For example, creating an Account and a Contact. If one interview in a transaction fails, all the interviews and updates in the transaction are rolled back.

Because multiple Salesforce organizations share the same resources, to prevent one organization from depleting all the resources Salesforce enforces governor limits per transaction.

Q11. When Does a Flow’s Transaction Start?

Depending on how the flow was distributed, a transaction that runs an interview for that flow starts in different ways. The below table list some of the events:

Distribution MethodTransaction Starts when …
Process BuilderA record is created or updated.
Flow URLThe URL is accessed.
Custom button or linkThe button or link is clicked.
Visualforce pageThe page is accessed.
REST API (Custom Actions or Flows resource)When the REST call is made. Depending on how the REST call is implemented, the limits can be shared with other operations.

Q12. When does a Flow’s Transaction End?

When a Flow’s transaction ends depends on flow elements it contains and how flow started. The Flow’s transaction ends when:

  • A Screen, Local Action, or Pause element is executed
  • The order of execution has completed—if the flow was triggered when a record was created or updated
  • All the interviews in the transaction have finished

Q13. Explain some of the Flow Elements.

Each Flow Element represents an action that the flow can execute. Flow builder provides following Elements

CategoryElement NameDescription
InteractionScreenCollect information from users who run the flow or show them some information.
InteractionActionPerform an action outside of flow.
InteractionSubflowLaunch another flow that is available in your org.
LogicAssignmentSet variable values.
LogicDecisionCreate paths for the flow to take based on conditions you set
LogicLoopIterate over a collection of values or records.
LogicCollection SortSort items in a collection.
LogicCollection FilterWithout changing the original collection, remove items based on a set of conditions.
DataCreate RecordsCreate Salesforce records using values from the flow.
DataUpdate RecordsUpdate Salesforce records using values from the flow.
DataGet RecordsFind Salesforce records and store their field values to use later in the flow.

Q14. What are Flow Connectors?

Flow Connectors determine the available paths that a flow can take at run time. On the canvas in Flow Builder, a connector looks like an arrow that points from one element to another.

LABELEXAMPLEDESCRIPTION
UnlabeledExample of unlabeled connectorIdentifies which element to execute next.
Decision OutcomeExample of outcome connectorIdentifies which element to execute when the criteria of a Decision outcome are met.
Pause Configuration LabelExample of event connectorIdentifies which element to execute when an event that’s defined in a Pause element occurs.
FaultExample of fault connectorIdentifies which element to execute when the previous element results in an error.
For each itemExample of next-element connectorIdentifies the first element to execute for each iteration of a Loop element.
After last itemExample of end-of-loop connectorIdentifies which element to execute after a Loop element finishes iterating through a collection.
Go To (Beta)Example of element connectorIdentifies which element to go to and execute next.

Q21. How can you Troubleshoot Salesforce Flows?

To troubleshoot a failed flow interview, use the flow fault email. To test the flow and observe what happens as it runs, use the debug option in Flow Builder. To view the failed flow interview in an interactive environment, click Flow Error: Click here to debug the error in Flow Builder in the flow fault email.

  • Emails About Flow Errors – Every time a flow interview fails, Salesforce sends an error email in the default language of the user who ran the flow. The email is sent to either the admin who last modified the associated flow or the Apex exception email recipients. The email includes the error message from the failure, details about each flow element that the interview executed, and a link to show the failed flow interview in Flow Builder.
  • Control Who Receives Flow and Process Error Emails – When a process or flow interview fails, a detailed error email is sent to the admin who last modified the process or flow. But perhaps that admin isn’t the best person to read and act on the details of what was executed and what went wrong. Instead, you can choose to send error emails to the Apex exception email recipients, which you specify and control in Setup.
  • Troubleshoot Flow URLs – If you’re distributing a flow and the custom button, custom link, or a direct flow URL isn’t working as expected, verify the referenced flow. In addition, verify its variables if you’re passing values into a flow from the URL.

Q22. What is an Invocable Method in Salesforce?

Invocable actions give developers an opportunity to write any complex logic in Apex and expose it into Flow Builder. In order to call an Apex method from Flow you will have to annotate that method with @InvocableMethod.
