Exception Handling Logic:

When using ExceptionType() and ExceptionDetail() functions, they must be used within the context of an active recovery stage. These functions retrieve details about the current exception.

Issue in Logic:

In the provided diagram, the Capture Exception Detail stage is executed as a multiple calculation stage but is not within a recovery block. Using these exception functions outside recovery mode can cause another exception.

Resulting Infinite Loop:

This causes a new exception each time the Capture Exception Detail stage is executed, leading to an infinite loop of exceptions as the process continuously tries to recover from the newly generated exceptions.

Blue Prism documentation on proper use of exception functions and recovery stages.

Process Definition Document (POD):

The POD captures the operational requirements of how the process is manually operated today and helps design how the process can be automated.

It includes detailed descriptions of the current manual process, the objectives for automation, and the steps needed to automate the process.

Role in Automation:

The POD serves as a blueprint for the developers, ensuring that all aspects of the current manual process are considered in the automation design.

It helps in identifying potential challenges and ensuring that the automated process meets the business requirements.

Understanding Blue Prism Flow Representations:

Blue Prism flow diagrams represent the logic and control flow of automated processes.

Each stage must follow the rules of the process flow, and certain configurations are invalid.

Analysis of Options:

Option A: Shows a timeout leading to an Exception stage, followed by an Email Alert. This is valid as it properly handles an exception and sends an alert.

Option B: Shows a timeout leading to a Resume stage, and then directly to an Email Alert. This is invalid because a Resume stage should be followed by logic to recover from the exception, not directly proceed to another action without resolving the issue.

Option C: Shows a timeout leading to a Recover stage. This is valid as it starts the exception handling process.

Option D: Shows a timeout leading to a Resume stage, followed by an Exception stage. This is valid as it properly handles exceptions by resuming and then throwing an exception if needed.

Conclusion:

Option B is the invalid representation because it incorrectly uses a Resume stage without properly handling the exception before proceeding to the next action.

The task is to create a date value from the ‘Day’, ‘Month’, and ‘Year’ data items. The correct Blue Prism expression in the ‘Convert to Date’ calculation stage would be:

MakeDate([Year], [Month], [Day])

This expression uses the MakeDate function to combine the year, month, and day into a full date. The order of parameters is important to match the environment’s date format dd/mm/yyyy.

[Year] - This is placed first within the MakeDate function to represent the year part of the date.

[Month] - This follows the year within the MakeDate function to represent the month part of the date.

[Day] - This is placed last within the MakeDate function to represent the day part of the date.

The closing parenthesis ) completes the function call.

To ensure that only credit transactions are included when calculating the total of customer credits, the 'Credit Transaction?' decision stage needs to check if the transaction code is between 50 and 99. Given that transaction codes are stored as text, we need to convert these values to numbers before performing the comparison.

Customer Transactions Collection:

The 'Transaction Code' column contains text values representing the transaction codes.

Credit Transaction Identification:

Credit transactions have transaction codes between 50 and 99.

Therefore, the correct condition should convert the text transaction code to a number and check if it is greater than or equal to 50.

Decision Stage Expression:

The correct expression is ToNumber([Customer Transactions.Transaction Code]) >= 50, which ensures that only credit transactions are included in the total calculation.

Understanding Environment Variables:

Environment variables are global variables that are accessible across multiple processes and sessions within Blue Prism.

They are typically used to store configuration settings and other information that need to be consistent across different processes.

Updating Environment Variables:

Internal - Global Variables Business Object (Option A): This business object can be used to update the value of environment variables programmatically within a process.

Calculation Stage (Option B): This stage cannot be used to update environment variables directly because it only works with data items within the context of the process.

Global Variables Store in Environment Manager (Option C): This is a specific area within the Environment Manager where environment variables can be managed and updated.

System Manager (Option D): This is another tool within Blue Prism where environment variables can be updated.

Conclusion:

The correct options to update the value of a data item exposed as an Environment Variable are:

A. Using the 'Internal - Global Variables' Business Object to update the value.

C. Using the Global Variables store in Environment Manager to update the value.

D. Using System Manager to update the value.
