You want to build a Dispatcher process to populate an Orchestrator Queue for parallel processing on multiple robots. Which activity should you use to add a queue item for each work item?

To populate an Orchestrator Queue with items for parallel processing, the appropriate activity is "Add queue item." This activity is specifically designed to send work items to a queue in UiPath Orchestrator, which can then be processed by multiple robots concurrently. Each time you use this activity, it creates an individual item in the specified queue, allowing for efficient management and distribution of workload among the robots.

Using "Add queue item" ensures that each work item is enqueued properly, making it available for retrieval and processing later by any of the connected robots. This functionality is essential for implementing a Dispatcher process, as it sets up the work items for the subsequent processing phase handled by different robots in parallel.

The other activities provided serve different purposes and are not suitable for this specific use case. For example, "Add transaction item" is typically used in the context of a transaction process where transactions are processed individually. "Get transaction item" retrieves items from a queue for processing by the Robot, and "Remove transaction item" is used to eliminate items from the queue after they have been processed, none of which aligns with the goal of adding items to the queue for parallel processing.
