The Misc field located under the Subtotal field and above the Tax fields at the bottom of the Sales Transaction Item Entry screen represents the total of the miscellaneous adjustments (the Discount and Shipping fields from the Complete Sales screen) to the Subtotal. The Misc field is automatically displayed when both the Discount or Shipping fields are enabled for the current Sales Transaction Type. If only the Shipping field or only the Discount field are enabled, the field is labeled accordingly (rather than being labeled Misc).
Note: It does not include discounts applied to individual line items on the Item Entry screen.
