Inventory below a fixed threshold does not necessarily lead to out-of-stock, and inventory above the threshold may not satisfy recent orders. Supply chain early warning should combine demand dates, available inventory and effective in-transit, so that personnel know which materials are missing and which tasks are affected.

How to arrange records and operations

Calculate changes in supply and demand based on the planned timeline, excluding frozen inventory and unconfirmed arrivals. Early warnings display assumptions and sources, and can drill down to order, delivery and inventory details. Processing actions include confirming arrival, adjusting plans and adding new replenishments, recording the responsible person, and preventing one reminder from being processed repeatedly by multiple departments.

Shortage warnings must present the demand date, existing available quantity, and confirmed supply based on them, and cannot only alert based on inventory falling below a certain value. Substitute materials, different factory stocks and unconfirmed arrivals can be used as alternative information, but cannot be mixed with guaranteed supplies. After the plan is adjusted, the impact scope of the original warning will be updated and handling opinions will be retained. When the gap reaches zero, it is also necessary to confirm whether the demand is canceled or the supply is filled. The page provides relevant order and material details so that purchasing personnel can decide to expedite, substitute or reschedule the demand.

Specific scenarios that need to be checked

For example, if a batch of materials in transit arrives later than the production picking time, the system should display the time gap. Test whether the warning is updated after demand cancellation, delivery date change and replenishment confirmation. Keep unaddressed and accepted risks separate, allowing the board to illustrate business decisions rather than just keep sending messages.
