Its use in the warehouse

It is calculated as locations counted without a discrepancy divided by locations counted, multiplied by one hundred: if 850 locations were counted in a month and 816 matched, accuracy was 96%. It is the foundation indicator of the warehouse, because picking, service and purchasing depend on a correct record. The formula, tolerance and sample must be the same every period for the figure to be comparable.
