The transformation shown in the exhibit converts a "tall" table (with attributes and values in rows) into a "wide" crosstable (where attribute values become column headers). The Generic prefix on a LOAD statement is the specific Qlik Sense feature designed for this purpose. It takes a key field (Customer), an attribute field (Product), and a data field (Sales) from the source table and pivots the attribute field's values into new fields in the target table, populating them with the corresponding data values.

A. HierarchyBelongsTo is a prefix used to transform an adjacency list (parent-child) table into an expanded nodes table for creating hierarchies, which is not the operation shown.

B. Peek is an inter-record script function used to retrieve a value from a previously loaded row, not a LOAD prefix for transforming table structure.

D. PivotTable is not a valid prefix for the LOAD command in the Qlik Sense data load script. It refers to a chart type, not a script transformation command.

1. Qlik Sense for Windows Help, "Generic": This official documentation describes the Generic prefix. It states, "The generic prefix can also be used to transform a generic table back into a crosstable." The example provided in the documentation mirrors the transformation required by the question.

2. Qlik Sense for Windows Help, "HierarchyBelongsTo": This document explains that the HierarchyBelongsTo prefix is used to load an adjacency list table and transform it into a table suitable for a hierarchy.

3. Qlik Sense for Windows Help, "Peek()": This page defines Peek() as an inter-record function that returns the value of a field in a table for a row that has already been loaded. It is not a table-level transformation prefix.
