Abstract

A computer-implemented method for counting stock stored in hierarchical levels at a facility is described. The method includes receiving count initiation information at a counting module. The count initiation information includes at least one parameter associated with stock to be counted and one or more hierarchical levels for the stock to be counted. The method also includes receiving quantity information associated with the one or more hierarchical levels, and generating count results based on the received quantity information. In certain embodiments, the quantity information can be received by multiple count activity objects associated with the counting module. Each count activity object can independently track separate portions of the quantity information.
