Explanation:

In Salesforce OmniStudio, a FlexCard is used to display data and actions, such as customer information and updates like billing details or contact changes. The scenario describes a FlexCard with 10 fields and 5 actions, where most fields display correct data, but one field shows only its label. This suggests an issue specific to that field's data retrieval or rendering.

Let's evaluate the options:

A. The fields have exceeded the maximum number allowed on the card.
This option is incorrect. OmniStudio FlexCards do not impose a strict maximum number of fields (e.g., 10 is well within typical limits). The fact that other fields display correctly further indicates that the total number of fields is not the issue.

B. The field is null on the Salesforce record.
This option is correct. If a field on the underlying Salesforce record is null (i.e., it contains no data), the FlexCard will display only the label without the corresponding value. This is a common behavior in FlexCards when the data source returns no value for a mapped field, leaving the field blank except for its label.

C. {recordId} is misspelled in the Data Source Input Map.
This option is incorrect. A misspelling of {recordId} in the Data Source Input Map would likely cause a broader failure, such as none of the fields populating, or an error in data retrieval. Since most fields display correctly, the data source is likely functioning, and the issue is specific to one field rather than a global misconfiguration.

D. There are no test parameters configured.
This option is incorrect. The absence of test parameters might prevent the FlexCard from loading data during testing, but the scenario states that several fields display correct data. This indicates that test parameters or data are configured and working, and the issue is isolated to one field.

Key Concept:
FlexCards rely on data from a data source (e.g., a DataRaptor or Integration Procedure) mapped to fields. If a field’s value is null in the source data (e.g., due to an empty field on the Salesforce record), the FlexCard will render only the label. To resolve this, the developer should verify the data in the Salesforce record or adjust the FlexCard to handle null values (e.g., with a default value or conditional display).

Reference:
This explanation is based on FlexCard configuration and data binding behavior in the Salesforce OmniStudio Developer Guide (available via the Salesforce Help portal).

Explanation:

A Calculation Procedure is used to perform complex multi-step calculations. Its structure involves:

Calculation Steps: These steps perform the individual operations (e.g., formulas, matrix lookups).
Aggregation Step: This final step gathers results from the calculation steps to produce the overall procedure output.
For the result of a calculation step to be available for use in the Aggregation Step, it must be explicitly defined in the Calculation Output of that step.

Here’s the logical flow:
Each calculation step has its own Input and Output configuration.
The fields listed in a step's "Calculation Output" are the results that step produces.
The Aggregation Step can only reference and combine outputs that have been declared in the Calculation Output of previous steps.
If a value is computed but not included in the Calculation Output of its step, it is considered an intermediate variable and is not passed forward to the Aggregation Step.

Why the other options are incorrect:

A. It must be included in constants:
Constants are fixed values defined in the procedure's setup. They are input into calculation steps, not the output from them.

B. It must be a matrix lookup step:
The type of step (e.g., Formula, Matrix Lookup) does not matter. Any step—whether it's a Formula, Matrix Lookup, or another type—must have its result included in its Calculation Output to be used later.

C. It must be a calculation step:
This is tautological (true by definition). The output in question is already from a calculation step. However, this statement misses the specific requirement that the output must be explicitly declared to be passed on.

Reference:
Salesforce OmniStudio Documentation:
The "Calculation Procedures" section explains the data flow. It explicitly states that the Aggregation Step "aggregates the output from multiple calculation steps," meaning it can only use what those steps have emitted in their output.

Explanation:

DataRaptor Extract Action
A DataRaptor Extract Action is the primary method for retrieving data from one or more Salesforce objects in OmniStudio.

It allows you to:
Query one or more related or unrelated objects using SOQL.
Filter the results using complex criteria.
Shape and transform the output JSON to your specific needs.
The retrieved data is then used by other OmniStudio components like OmniScripts or Integration Procedures.

Lookup Input Element
A Lookup Input Element is a component used within an OmniScript. It is a user-facing field that provides a real-time search of Salesforce objects. When a user starts typing, the Lookup element performs a query to retrieve matching records from a specified Salesforce object, presenting the results in a dropdown list. It's an interactive way to retrieve a single record's ID and related data.

Why the Other Options Are Incorrect?

A. A DataRaptor Load Action: A DataRaptor Load Action is used to write or update data in Salesforce objects. It takes a JSON input and maps the data to create or modify records. It is not used for retrieving data.

D. A DataRaptor Post Action: This is a component in an OmniScript that is used to invoke a DataRaptor Load. Like the Load action itself, its purpose is to create or update data, not retrieve it.

Explanation:

DataRaptor Extract Action
A DataRaptor Extract Action is the standard way to query and retrieve data from Salesforce objects in OmniStudio. In this scenario, the developer needs to get device details from the Asset object. The DataRaptor Extract is the perfect tool for this because it can:
Query the Asset object using a SOQL-like query.
Filter for a specific device.
Shape the output data into a JSON structure that can be easily used by the next element.

HTTP Action
An HTTP Action is used to make a direct call to an external REST API. In this case, the developer needs to send troubleshooting commands to an external system via REST API. The HTTP Action allows the developer to configure all the necessary components of the REST call, including:
The API endpoint URL.
The HTTP method (e.g., POST, GET).
Any required request body (payload) using JSON data from the OmniScript.
Custom headers, such as for authentication.

Why the Other Options are Incorrect

B. REST API Action:
There is no standard OmniScript element called "REST API Action." The correct element for making external REST calls is the HTTP Action. While an Integration Procedure can have a HTTP Action to make a REST call and an Integration Procedure Action can be used to call the Integration Procedure from the OmniScript, the HTTP Action itself is the direct tool for this purpose.

C. Navigation Action:
A Navigation Action is used to redirect the user to a different page or a new OmniScript. It does not retrieve or send data.

D. SOQL Action:
There is no standard OmniScript element called "SOQL Action." Data retrieval from Salesforce is handled declaratively using a DataRaptor Extract. The DataRaptor uses SOQL internally, but the developer does not write the SOQL query directly in the OmniScript.

Explanation:

In Salesforce OmniStudio, the CONTIF function (likely a typo for CONCAT or a custom function intended to concatenate values) is used to process and combine data, such as user-entered input in an OmniScript. The requirement specifies that the output of this function needs to be displayed to the user immediately in the current step, indicating the need for real-time calculation and display within the OmniScript interface.

Let's evaluate the options:

A. A Calculation Action element
This option is incorrect. A Calculation Action element calls a Calculation Procedure to perform complex calculations, which are typically processed in the background and may not provide immediate display in the current step. It is better suited for server-side logic rather than real-time user feedback.

B. A Set Values element
This option is incorrect. A Set Values element is used to assign values to variables, often based on conditions or calculations, but it does not inherently display the result to the user. The output would need additional configuration (e.g., mapping to a display element), which does not meet the "immediate display" requirement efficiently.

C. A Formula element
This option is correct. A Formula element in an OmniScript allows developers to define formulas (e.g., using functions like CONCAT) to process user input in real time. The result can be bound to a display field or variable, enabling immediate display to the user in the current step. This aligns with best practices for handling simple calculations and displaying them directly in the UI.

D. A Range element
This option is incorrect. A Range element is used to create a slider or input range for users to select a value within a specified range. It is not designed to process data with functions like CONTIF or display calculated outputs immediately.

Key Concept:
Best practices for OmniScript development recommend using a Formula element for real-time processing and display of calculated values, such as concatenating user input. This element supports functions and can be linked to a display component, ensuring the user sees the result immediately without requiring additional actions or server calls.

Reference:
This explanation is based on OmniScript element usage in the Salesforce OmniStudio Developer Guide (available via the Salesforce Help portal), particularly the section on Formula elements and their application in user interfaces.

Explanation:

The requirement is to take the JSON response from a REST API (HTTP Action) and convert it into a specific XML structure. This is a classic data transformation task.
A DataRaptor Transform is the core OmniStudio tool designed for this exact purpose. Its primary function is to reshape data from one format to another.

Here's how it fits:
Input: The JSON response from the HTTP Action can be fed into the DataRaptor Transform.
Mapping: The developer can map the JSON fields from the input to the desired nodes and structure in the XML output using the Transform's interface.
Output: The DataRaptor Transform can be configured to output its result in XML format, creating the specific structure needed for the next web service call.
This approach is declarative, managed within the OmniStudio toolkit, and follows best practices.

Why the other options are incorrect:

A. Use a Remote Action that calls the XMLStreamReader class & B. Use a Remote Action that calls the XMLStreamWriter class:
These options suggest using Apex code (via a Remote Action element). While technically possible, this is an imperative solution where a declarative one exists. Using custom Apex code is less efficient, harder to maintain, and bypasses the built-in, powerful transformation capabilities of DataRaptor. It violates the low-code principle of OmniStudio unless there is an extremely complex transformation need that DataRaptor cannot handle.

D. Use a DataRaptor Extract and check the XML checkbox on the Output JSON Path:
This is incorrect because a DataRaptor Extract is used to query and retrieve data from Salesforce objects (or via a custom query). It is not designed to transform an existing JSON payload from an HTTP call into XML. The "XML checkbox" on an Extract defines the format of the data it queries, not the format it outputs from a transformation.

Reference:
Salesforce OmniStudio Documentation: The "Create a Transform DataRaptor" section explicitly covers its use for converting between JSON and XML formats. The documentation highlights mapping input fields to output XML elements.

Explanation:

The PREVIEW tab in OmniScript allows developers to simulate the script execution and verify whether the DataRaptor Extract is correctly retrieving and displaying data.
It provides immediate feedback without needing to deploy or navigate through the Lightning Console.
You can inspect the JSON response, check mappings, and confirm that the expected fields are populated.

🛠️ Why the other options fall short:

A. Lightning Console reload: This is more of a UI-level test and doesn’t directly help isolate DataRaptor issues.

C. Deactivating card/layout: Unnecessary and unrelated to testing data retrieval.

D. Adding key/value pair: Might help in testing mappings, but it’s not the first step—you’d do this after confirming the issue in Preview.

Explanation:

Account information must always be visible → This should be placed in a standard block or text elements on the FlexCard, no conditional logic needed.

Contact information should only be visible when needed → The best pattern is to place the contact details inside a block element and then set its collapsible property.
This adds an expand/collapse toggle, allowing the user to click and show/hide the content on demand.
This is a common design choice when you want "on-demand visibility" for secondary information.

❌ Why the other options are incorrect:

A. Use a Data table element → A data table is for listing multiple records (e.g., lists of contacts), not for selectively showing details about a single contact. Doesn’t solve the show/hide requirement.

B. Set the class ‘collapsible’ on the block element → This isn’t the right approach. You don’t manually set a CSS class to make FlexCard elements collapsible. There’s a built-in property for that.

D. Use a conditional FlexCard State → States are used to render different layouts based on conditions (e.g., error, active, inactive). Not appropriate here — we don’t want different layouts, just toggled visibility.

📖 Reference:
Salesforce OmniStudio FlexCard Designer Guide → Block Elements:
“Block elements can be configured with the collapsible property, which lets users expand or collapse the section content.”

Explanation:

The Id Field for Actions in the FlexCard specifies which field from the FlexCard data source will be used as the record ID for the OmniScript. If this field is blank, the OmniScript will not receive any record ID and will not be able to retrieve any Salesforce data. In the DataRaptor Extract Action, the Input Parameters Filter Value determines how to filter the data based on the record ID. If this value is misspelled, the DataRaptor Extract will not be able to match the record ID and will not return any data.

Explanation:

According to the OmniStudio Developer Guide, “To return a response from an Integration Procedure, add a Response action as the last action in your Integration Procedure.” Therefore, the correct answer is C.

Explanation:

A DataRaptor Turbo Extract is a simplified version of a DataRaptor Extract that can retrieve data from a single object without changing the structure of the output data. It is suitable for this scenario because the developer does not need to transform or load the data

Explanation:

A DataRaptor Extract can retrieve data from multiple objects using extraction steps and JSON paths. However, if the data is from a single object, only one extraction step is needed. The Extract JSON Path can use dot notation to access related fields from that object, such as Contact.Account.Name.
