Hey @Kritika, A Queue is a container that enables you to hold an unlimited number of items. Queue items can store multiple types of data, such as invoice information or customer details. New queues created in Orchestrator are empty by default. To populate queues with items, to change their status and process them, you have to use Studio activities. As soon as queue items are processed, they become transactions.
Queues enable you to create large automation projects underlied by complex logic. Item Statues are controlled by RPA developers when they create the automation projects, while Revision Statues are controlled in Orchestrator and enable you to perform version control, but only of queue items that have been abandoned or have failed with an application or business exception. The Queues page enables you to create new queues. It also provides you with viewing access on previously created queues, charts with the transaction status progress over time, and on various other details, such as average execution time and the total number of successful transactions.
The Transactions displays the transactions from a given queue. It also shows their statuses, the dates when they should be processed, the Robot that processed them, and the type of exception thrown or assigned reference, if any. You can search for a specific transaction or a group of them, according to a custom reference, which is added through the Reference property of the Add Queue Item and Add Transaction Item activities. The reference can be used to link your transactions to other applications used within an automation project. Additionally, this feature enables you to search for certain transactions in Orchestrator, according to the provided custom reference.
