When creating a queue in UiPath with the “Unique Reference” option enabled, it ensures that each item added to the queue has a unique reference. If you decide not to use the unique reference option,
Ensure the “Unique Reference” option is unchecked when you create or update the queue in Orchestrator.
If you choose not to use unique references, you do not necessarily have to remove the reference column. The reference column can still be used for other purposes, even if the values are not unique.
If you already have a queue with the “Unique Reference” option enabled and want to switch to non-unique references, you will need to update the queue settings in Orchestrator.
Thank you, @Anil_G
So when I create a new queue with no unique reference, I can add the same data again? Even though I have reference column set in my code while adding queue item, correct?
