Clear Negative Cost Tiers

The issue or sale of an item is allowed, even if there is not enough quantity on hand. This situation results in a negative cost tier for LIFO or FIFO valued items. The last cost for an item is used for the posting of the sale when the negative (over distributed) tier is created.

To clear negative cost tiers

Select Inventory Management Period End menu > Inventory Negative Tier Adjustment.
Click Print. The register prints all LIFO/FIFO items that have a negative cost tier for which there is one or more corresponding positive cost tiers that can be used to adjust the quantity.
After printing the Negative Tier Adjustment Register, click Yes to proceed with the update. If there is a difference in cost, print and update the Daily Transaction Register to post the entry to the general ledger.
