The Timeout property on the HTTP Action in the Integration Procedure specifies how long to wait for a response from the external system before throwing an error. The Chain On Step checkbox on the HTTP Action in the Integration Procedure indicates that the next action should be executed only if the current action is successful. These two configurations should be used to implement the call to the external system given its known performance issues. 

According to the OmniScript Action Elements page, a DataRaptor Extract Action can be used to “get data from one or more Salesforce records” and an HTTP Action can be used to “get, save, or delete data through a web application programming interface (API)”. 

From OmniStudio Best Practices for Modular Script Design, OmniScript Actions are the preferred mechanism to invoke another OmniScript within a parent OmniScript. This approach enables reusability and modularization, especially when a function (like updating billing information) is common across many interactions.

A. OmniScript Action – This is the correct and standard method for embedding or launching one OmniScript from another. It allows developers to reuse common scripts without duplicating logic.

Incorrect Options:

B. Custom Action requires custom Apex or LWC development, which is unnecessary for this use case.

C. Lightning Action is typically used to invoke OmniScripts from Lightning pages, not within OmniScripts themselves.

The Repeatable Mode property on the data table elements allows the developer to display multiple records in a single data table. The Repeat Records feature on the FlexCard Setup tab is used to display multiple FlexCards for each record in a data source. The Record Looping feature on the data table elements is used to iterate over a list of records and perform actions on each record. The Overwrite Target for all Null input checkbox on the Account id field is used to overwrite the existing value in the target object with null if the input value is null.

The Expression Set component in OmniStudio allows developers to perform calculations using steps such as Aggregation, Calculation, and Sub Expression.

C. Add an Aggregation Step as SUM(BasePrice) – This is correct. Aggregation steps are specifically designed to perform functions like SUM, AVG, COUNT, MIN, MAX over collections (arrays) of data. In this use case, summing the entire BasePrice array is best handled using an Aggregation Step.

Incorrect Options:

A. Sub Expression Step is used to combine or manipulate previously calculated values, not to aggregate across an array.

B. Calculation Step is used for row-level calculations, not aggregation across multiple rows.

 According to the FlexCard Designer Overview page, another possible cause of a field showing only the label is that “the field is null on the Salesforce record”.

According to the OmniScript Data JSON page, the OmniScript structure JSON defines the data elements and their properties that are used in an OmniScript. The exhibit shows an OmniScript structure JSON with six elements: AccountName, AccountNumber, AccountType, AccountOwner, ContactName, and ContactPhone. The DRGetAccountDetails action is a DataRaptor Extract action that retrieves data from the Account and Contact objects in Salesforce. The BlkContacts element is a Repeat Block that displays a list of contacts related to the account. Therefore, the JSON from the DRGetAccountDetails action that would display all six values correctly in the OmniScript structure shown is option C, which has the following structure:

{The other options have different structures that do not match the OmniScript structure shown. Therefore, the correct answer is C.
