The OPC Threshold field relates to opportunity counts, which you can specify. When inventory is taken out of the location, the system checks whether the quantity on-hand falls below the threshold level you specify for the item, and also checks the OPC frequency value for the location where the item is stored. If both conditions are met, a cycle count is requested.

You can specify an OPC threshold value for each item, and also for items related to a specific zone.

The graphic above shows three screens for item, site, and zone where you can set up the OPC threshold.
