What it is for
Checking a specific sale
Find it by receipt reference when a number is disputed.
Confirming an import landed
After an import, check that a day you know was busy actually has lines.
Reading margin here
Margin is computed from the cost captured at the time of the sale. A line with an unusually high margin is worth a look: it often means the product had no cost basis when it sold — stock that was never received, or received at zero cost.A run of 100% margin lines is not good news. It nearly always means the
purchase side is missing, so check that the deliveries for those products were
checked in.
