Inventory Count Settings are the rules governing the process of counting physical items (SKUs) in inventory. These rules contain information about how many times you need to count certain items and what counts and/or dollar amounts are considered acceptable (if they don't correspond to the inventory totals in the IDI solution).
Inventory Count Settings are usually set at the global location level since they rarely change.
To configure Inventory Count Settings, from the Inventory Count Settings form:

either click Inherit Inventory approval plan from 'global' to inherit settings,
OR
click Override Inventory approval plan Settings to make changes.
Note
If you're on the Inventory Count Settings for Global window, there are no inherit nor override options.
Make any changes to the following fields.
Maximum Iterations - Maximum Iterations refers to the maximum number of times that the inventory count may need to be performed. For example, if this number is set to 3, and the first count fails the variance, then 2 more counts may be done, if necessary.
Max Variance % (Number of items) - The Max Variance % (Number of items) is the maximum number of items per SKU by which a count can be off.
Max Variance Amount ($) - The Maximum Variance Amount is the maximum dollar amount of the difference between the manual count and the system count for a specific item.
Recount Products Outside of Variance Only - Check this box to indicate if only those products that are out of the recount variance need to be counted again.
Count Discontinued Items - Check this box if items that are classified as discontinued needed to be included in an inventory count.
