I am trying to create a saved search that identifies any duplicate items on a sales order. I would think a grouping on Transaction, Item and then a Count on item would bring back '2' for any items more than once would be the result, but I cannot make this work for some reason. I just want a report that shows when an item is entered twice on the same transaction. Any suggestions?

Group by transaction internal id or document number, Item. Count line unique key or line id.

I can confirm raghav’s answer is correct

Fantastic! Thanks that worked.
