I was sure that the only status ignored by the “unique reference check” is “Deleted”.
But apparently I was able to upload two items with the same unique reference, one “New” and the other “Succesful”.
I need that the queue strictly permit only unique items, ignoring deleted items only.
Can someone help me?
Edit: I want to add that the queue is correctly set to “yes” use unique reference. It correctly cannot holds two “New” items with the same reference.
