Examine the following Blue Prism Process diagram:

The 'Retry Limit' data item is configured as a number data item, and has an initial value of 3. The 'Retry Count* data item is configured as a number data item, and has an initial value of 0. The 'Count' Calculation stage increases the value of the 'Retry Count' data item by 1. The 'Retry? Decision stage contains logic to prevent more than 3 attempts

What is wrong with the current configuration?

D.
The retry loop logic does not include any actions after the resume stage to ensure the application is ready to try the 'Search Screen - Perform Search' Action again
Suggested answer: D

Explanation:

Understanding the Diagram:

The diagram shows a retry loop where the process attempts to perform a search, read results, and handle exceptions by retrying up to 3 times.

'Retry Limit' is set to 3, and 'Retry Count' starts at 0 and is incremented by 1 in each retry attempt.

Analyzing the Logic:

Option A: The Resume stage should resume the process outside the exception block, which is correct.

Option B: Exception handling in the process layer is valid; it does not have to be exclusively in the object layer.

Option C: Each action does not need an individual retry loop; the overall block retry is acceptable.

Option D: This option highlights a missing step. After handling an exception and before retrying, the application needs to be reset or ensured it is ready to retry the 'Search Screen - Perform Search' action.

Identifying the Issue:

The retry logic should include steps to ensure the application state is appropriate for another search attempt. This might include resetting fields, waiting for the application to be ready, or ensuring the previous error state is cleared.
