A Prism data writer needs to create a new Prism calculated field on a derived...

Comprehensive and Detailed Explanation From Exact Extract:

In Workday Prism Analytics, when creating a calculated field in a derived dataset, users often need to reference existing fields in the dataset within their expressions, such as in a CASE function. According to the official Workday Prism Analytics study path documents, to view and select from a list of available fields in the dataset while building a calculated field expression, the user types the [ symbol (left square bracket). This symbol triggers a dropdown list of all fields in the dataset, allowing the user to select the desired field without manually typing its name, reducing the risk of errors. For example, typing [ and selecting a field like "Employee_ID" will insert [Employee_ID] into the expression, which can then be used in the CASE function logic.

The other symbols do not serve this purpose:

B. (: Parentheses are used for grouping expressions or defining function parameters, not for field selection.

C. #: The hash symbol is not used in Prism Analytics for field selection; it may be associated with other functionalities in different contexts.

D. {: Curly braces are not used for field selection in Prism Analytics; they may be used in other systems for different purposes, such as templating.

The use of the [ symbol ensures an efficient and accurate way to reference fields in a calculated field expression, streamlining the creation process in Prism Analytics.
