Orchestraror queue

Is it possible to update existing queue item in UiPath? I want to one of the field after processing it. Please confirm.

You’ll need to do that through Orchestrator APIs. Refer: How to update the queue items after adding the items to it - Help / Studio - UiPath Community Forum

in some cases we can use the output field, which can be set along with the transaction status. So we keep the origin values for audit purposes
