What are the “Credits” and “Debits” checkboxes for?
These checkboxes will restrict your results to include only the specific transactions that you would like to see. For example, if you want to see only refunds, you would uncheck all the boxes under “Credits”, then uncheck all the boxes under “Debits” except “Refunds”, then select “Go”. Note that you can also select “all” next to either “Credits” or “Debits” to check or uncheck all the boxes in that category.
