The Edit Block element is the ideal OmniScript component for this scenario as it is specifically designed to display and manage an array of sObjects, natively supporting add, edit, and delete functions for list items. To process the resulting data—which will be a mix of new, updated, and deleted records—a Remote Action is used. This action calls an Apex class method to handle the complex data manipulation language (DML) operations in a single, controlled server-side transaction, ensuring data integrity when saving the changes to the dependent records.

A Text Block element is used for displaying static, non-interactive text and cannot be used to capture or manage user input for a list of records.

An Input Block is a generic container for input fields but lacks the built-in functionality of an Edit Block to dynamically add, edit, and remove records from a list.

SOQL (Salesforce Object Query Language) is used for retrieving data, not for performing DML operations. An action element, not a SOQL statement, is required to save data.

Edit Block Element: "The Edit Block element enables a user to edit one or more fields in a list of sObjects... Edit Blocks support adding and deleting items from the array." This confirms the Edit Block is the correct UI element for managing a list.

2. Salesforce OmniStudio Documentation

Remote Action Element: "Call an Apex class and method from an OmniScript. Remote Actions are commonly used to save data to an sObject or perform other functions that are difficult to do with a DataRaptor." This supports using a Remote Action for the complex save logic required for a list of adds

edits

and deletes.

Text Block Element: "Display static instructional text in an OmniScript." This confirms it is not an input element.
