The 'Buffer Level' is essentially the 'Minimum Order Quantity To Purchase' of an Inventory Item for a specified Warehouse. This field is used as a measure for the 'Buffer Status' field, a visual indicator that allows the user to easily see where stock needs to be replenished.
Setting the 'Buffer Level' for your Inventory Items will also allow the Replenishment document to calculate a 'Suggested Qty' on your 'Replenishment Suggestions'.
To set the 'MOQ To Purchase' and 'Buffer Level' navigate to 'Inventory' > 'Processing' > 'Inventory Items' and open the Inventory Item you wish to setup.
Navigate to the 'Multi-Warehousing' tab. Here you can set the 'Buffer Level' for this Item at each Warehouse.
The 'MOQ To Purchase' is set on the 'Linked Suppliers' tab. Here a supplier can be linked to an Inventory Item for a specific warehouse.
Buffer Status
The 'Buffer Status' is calculated based on the penetration of the 'Buffer Level' by the 'Qty In Buffer' field
If the 'Buffer Level' is not set, then the 'Buffer Status' will be blank or appear as a light grey.
Calculating 'Qty In Buffer' the 'Buffer Status' is set as follows:
- Above Max: Blue
- Below Max and Above 2/3: Green
- Below 2/3 and Above 1/3: Amber
- Below 1/3 and Above 0: Red
- No Stock (0): Black
Qty In Buffer
The 'Qty In Buffer' field is calculated as the net value of the following fields :
Qty In Buffer = QtyOnHand - QtyOnDeliveryShipment + QtyOnCreditNote - QtyOnRTS - QtyOnAdjustOut + QtyOnAdjustIn + QtyOnGoodsReceivedNote - QtyOnInvoice + QtyOnPurchaseOrder + QtyOnWIPOut.
