I am trying to find all transactions that makes up the Bin on Hand amount for a certain widget. In my criteria I am using Transaction Bin number is "Bin777" and for results I am pulling in Transaction Bin Quantity. Some of them add up to the correct amount and some of them do not. Am I missing something simple?

Is it possible the same Bin is used in different types of transactions, effectively duplicating results?

Multiple lines or multiple lots or multiple units of measure.
