The two scenarios where a DataRaptor should be used are: to retrieve an account and its related contacts, and to merge the city and state fields into a single field. A DataRaptor is a tool that can read, transform, and write data from Salesforce objects or JSON objects. A DataRaptor Extract can retrieve data from one or more Salesforce objects using SOQL queries, and store it in an Interface object or a JSON object. A DataRaptor Transform can map data from one Interface object or JSON object to another, and apply formulas and functions to transform the data. For example, a DataRaptor Transform can concatenate two fields into one using the + operator

Explanation
The consultant can improve the user experience of the OmniScript by using a Section element to break the information and a Headline element to add the title and a required icon in the input. A Section element can group related fields and elements in a logical way, making it easier for the user to navigate and fill the information. A Headline element can display a label and an icon for each field, indicating which ones are mandatory. This way, the OmniScript can display the information in a specific order and prevent errors and failures

Explanation
The two OmniStudio tools that should be recommended to meet these requirements are Calculation Procedure and Calculation Matrix. Calculation Procedure allows the designer to define a multi-step calculation process that can use data from various sources. Calculation Matrix allows the designer to define a table of values that can be used as inputs or outputs for calculations. In this case, a Calculation Matrix can be used to store the discount thresholds based on region and customer lifetime score, and a Calculation Procedure can be used to apply them to the orders. OmniStudio Action is not needed for this scenario, as there is no interaction involved. DataRaptor Transform is not suitable for this scenario, as it is used to transform data from one format to another.
