Comprehensive and Detailed Explanation From Pega Robotics System Exact Extract:
In Pega Robot Studio, the DataTableProxy component acts as an intermediary between automations and a Data Table, allowing the automation to read, manipulate, and update tabular data stored in the project.
When you drag an element such as a DataTableProxy from the Globals section of the Palette onto the automation design surface, Pega Robot Studio presents the user with available actions (methods, properties, or events) that can be executed using that component. This is done through a Select Action dialog box, which lists all available methods associated with the DataTableProxy (e.g., GetTable, AddRow, RemoveRow, Find, Update, etc.).
From the Pega Robotics System Design and Implementation Guide (Data Table Proxy and Data Handling section):
“When a component such as a DataTableProxy or connector object is dragged from the Palette onto the automation design surface, the system opens the Select Action dialog box.
This dialog lists all available methods and properties of the selected object, allowing the developer to select the action to instantiate on the automation surface.
The dialog ensures developers can directly add the desired operation (such as GetTable or UpdateRow) without manually searching through the object’s members.”
Detailed Reasoning:
The DataTableProxy represents a data-handling object; it does not directly add a “property” or “method” by default when dragged.
Instead, Robot Studio prompts you with a Select Action dialog box, allowing you to choose which specific method (like GetTable, FindRow, or AddRow) you want to include in your automation.
After the selection is made, the chosen method (for example, GetTable) is then displayed on the automation surface.
Option Analysis:
A. Incorrect — A property is not automatically added; you must choose an action first.
B. Incorrect — The Quick Add dialog is used for linking variables and not for proxy components.
C. Incorrect — A “proxy design block” is not automatically added without specifying a method.
D. Correct — The Select Action dialog box opens to let you choose the method or property to add.
E. Incorrect — GetTable may be one of the options available, but it is not added automatically.
Hence, the correct answer is D — dragging a DataTableProxy from the Globals section triggers the Select Action dialog box to open, allowing the developer to choose which action to use.
