A Decision stage checking for element visibility after a Wait stage provides explicit, clear control flow. It is more maintainable than relying on exception handling for business logic (options A & C), and more precise than application recovery (option B), which is for unexpected errors, not expected application states.

Loading all data into a collection before processing holds it in the process’s memory for the loop’s duration, which can be inefficient. Using a Queue (with the Queue Item ID passed to the process) is a core Blue Prism best practice for workload distribution and memory management, feeding work items one by one.

The Left([text], [number]) function returns the specified number of characters from the start of the text string. “US-12345” has 8 characters. Taking the left 5 characters results in “US-12” (U, S, -, 1, 2).

Region mode identifies elements by their screen coordinates (X, Y, Width, Height). If the application window is moved, resized, or the screen resolution changes, the coordinates become invalid, causing the automation to fail. It is a fragile method compared to methods using intrinsic properties.

Communication from an Object Action to a Process is done via Output parameters. You must first define the Output parameter on the Action’s properties. Then, inside the Action’s page, you use a Data – Output stage to assign the value from a data item or calculation to that specific output parameter.

The Process Report provides a step-by-step log of the process execution, including the exact stage where the failure occurred, the values of data items at that time, and the full technical details of the exception. This is the primary tool for debugging a failed process run.

Blue Prism provides a specific ‘Password’ data type. When set, the value is stored in an encrypted format within the process or object, and it appears masked in the studio and logs. This is more secure than plain text constants, hard-coding, or external files without encryption.

The ‘Prevent Overlapping Sessions’ option is a built-in feature of Blue Prism schedules. When enabled, the Control Room will check if a session for that process/queue is already running. If it is, it will skip launching the new scheduled session, preventing concurrent runs and potential conflicts.

Blue Prism Environment Variables are designed for this exact purpose. You can define a variable (e.g., “TemplateFilePath”) with different values in your Dev, Test, and Live environments. The process references the variable name, and Blue Prism automatically uses the correct value for the environment it’s running in, promoting separation of configuration from logic.
