Blue Prism Interview Questions 121-140

121) What are Mark Complete and Mark Exception actions?

As we have seen, results are applied to a queue item with the Mark Complete and Mark Exception actions. There are also a number of other ways to update an item before a result is applied. A common use of these actions is change the item’s tags to match the result. The left hand side of the following diagram illustrates the ‘complete’ path; the right hand side is the ‘exception’ path.

122) What is the use of Tags?

Tags are a useful way to facilitate MI reporting by labeling items by exception type.

123) What is standard Blue Prism Performance Report?

The standard Blue Prism Performance Report requires that all exception items are tagged as either ‘System Exception’ or ‘Business Exception’.

124) What is your approach in the event of a serious problem with an application?

In the event of a serious problem with an application, it may be better for a process to stop rather than carry on working. A better solution would be to count consecutive occurrences of an exception and bring the process to a stop when a sensible limit is reached.

125) What is Blue Prism work queue?

Blue Prism work queue can be set up to enable an exception item to be reworked. It does this by creating a clone of the item and injecting it into the queue at the same position as the original.

126) What is recovery mode?

It can be a good tactic to minimize the time spent in Recovery Mode by capturing the details of an exception in data items and then moving directly to the Resume stage.

127) What is a Page what does it contain?

A page can have multiple Blocks, as long as they do not overlap.

128) What is System Unavailable Exception?

A System Unavailable Exception may be thrown by an action or a sub-page if you are unable to launch your application. If such an exception occurs it is not related to an issue with a Work Queue item that might be currently being worked, you may, therefore, want to simply unlock the item (i.e. by Refering it) rather than marking it as an exception.

129) What is Mark Exception?

The Mark Exception action has flag inputs called Retry and Keep Locked for controlling this feature. If a new item is created, its ID will be returned in the New Item ID output parameter, and if Keep Locked was set to True, the process will have control of the new item

130) What will be attached to an application, when it is launched?

Launching an application attaches the business object automatically.

131) Can you explain why exception occur while launching application?

Once a business object has launched an application, any attempt to launch again will cause an exception. Once a business object has become attached to an application, any attempt to attach again will cause an exception.

132) How do you check if the object is attached to the application?

To check if the object is attached, use the root (top) element in the application model and select the ‘Is Connected’ read operation.

133) What is the purpose of a Business Object in blue prism?

The purpose of a Business Object is to provide an interface to one application

A Business Object is not exposed to Control Room and is never used on its own – it is always used by a Process

134) What are input and output parameters?

Data are transferred between a Process and a Business Object via input and output parameters.

135) How can you exit from spy more in blue prism?

To exit spy mode, it’s CTRL+right-click.

136) What is the use Data Items?

Use Data Items to store timeout values. You should use Data Items to store timeout values so that you can modify multiple Wait stages with one easy change to a Data Item.

Business Objects should data items to store timeout periods makes it easy to re-configure how long an application should wait for different types of system activity.

137) What is a wait stage?

A wait stage without any wait condition can be used to create pause, and a Data Item can be used to control the length of the timeout. Be generous with timeouts – overestimate rather than underestimate.

Using this arrangement it is possible to create a “throttle” by placing Wait stages controlled by a global Data Item at key positions in a Business Object. Typically this could simply be done by starting every page with a “throttled” Wait stage.

The “Throttle” global Data Item can be used to manipulate the pace of a Business Object are not adversely affected by being closed in this way, it is important to remember that some are and that a gentler, less severe Close method is required.

138) What is write stage?

As the name suggests, the Write stage is used to put values into elements and the properties form is laid out with a list of Data Items on the left and the elements on the right. The middle section is where we indicate which values want we want to go into which elements.

139) What is Attach?

Attach needs an input value to help it identify the application. Like “Window Title” or “Process Name”

140) What are Inputs to a page in Object Studio?

Inputs to a page in Object Studio provide the means for a Process to supply data to the Business Object.
