Reordering Policy is the field on an item or stockkeeping unit that tells Business Central which planning method to use when it proposes replenishment.
Reordering Policy determines how Business Central calculates a replenishment suggestion for an item. The standard options are blank, Fixed Reorder Qty., Maximum Qty., Order, and Lot-for-Lot. The policy decides whether planning reacts to a reorder point, to one specific demand line, or to demand grouped inside a time bucket.
You set the field on the Item card, on the Planning FastTab, which you reach by pressing Alt+Q, searching for Items and opening the item. If you plan per location or per variant, the same field exists on the Stockkeeping Unit card, and the stockkeeping unit value is the one planning uses. The resulting suggestions appear when you run Calculate Plan in the Requisition Worksheet or the Planning Worksheet.
Item BRG-1000, a bearing bought from Fabrikam, uses Fixed Reorder Qty. with Reorder Point 200 and Reorder Quantity 500. On 12 March 2026 inventory drops to 180 pieces, so the requisition worksheet proposes a purchase order for 500 pieces. If the same item used Lot-for-Lot, planning would instead propose only what the open demand in the time bucket needs, for example 140 pieces.
The most frequent mistake is leaving the policy blank and still expecting suggestions: a blank policy means the item is ignored by planning. The second is setting a reorder point without a reorder quantity, which produces suggestions of an unusable size. A third appears when stockkeeping units exist: a policy changed only on the item card has no effect for that location, because the stockkeeping unit takes precedence.
Reordering parameters drift as demand changes, so reorder points and quantities are worth reviewing against the last twelve months of item ledger entries at least once a year. Zentriq Agent can answer questions such as which items fell below their reorder point last month directly against your Business Central data, and any purchase document it drafts still has to be approved and posted by a person.
Fixed Reorder Qty. is the usual choice for an item you keep on the shelf and buy in a standard batch size. Lot-for-Lot fits items you buy only when demand exists.
Check that Reordering Policy is not blank and that the item is not blocked. If a stockkeeping unit exists for that item and location, the policy on the stockkeeping unit is the one that counts.
