After you have your warehouses set up, be sure to use the appropriate view to handle forecasting and replenishment for your store.
Combined warehouses should be used for replenishment planning based on a "global" view of stock and/or sales information.
If you need to evaluate forecasting and replenishment for individual selling locations or warehouses, make sure to Enable them in Account > Settings > Connections & Warehouses so they appear as selectable warehouses through Replenishment and Reporting. Otherwise you can disable individual locations/warehouses if it's sufficient to include them in the combined warehouse view.
Warehouse marked as Enabled in appear in the main Replenishment screen when "All Warehouses" is selected, and in the the location dropdown in the top left of the scren.
In a Combined Warehouse a (?) icon appears next to stock and sales related metrics. Click this button to see how data breaks down by location.
Note: if an option was selected to "ignore" the stock (or sales) information from a specific location, they still appear in this view - but are not counted in the displayed amount on the main Replenishment table.
Forecasts and Replenishment are created independently for a combined warehouse. Adjustments in a single warehouse do not impact forecasts or replenishment recommendations in a combined warehouse. If stock cannot be transferred or shared between warehouses to fulfill customer orders, you should create purchase orders using forecasts and replenishment for each individual location/warehouse instead.
You will need to configure lead time and days of stock for your Combined Warehouse independently. A new warehouse will default to 14 days lead and 30 days of stock.
The Lead Time inputted should represent the time between placing a purchase order to the supplier, and receiving the new stock at your fulfillment location. If there are multiple fulfillment locations (eg. Amazon FBA), it is recommended to use the greatest Lead Time to consider the full amount in replenishment recommendations.
The Days of Stock inputted should represent the desired coverage once stock arrives. Inventory Planner forecasts your stock position for Variants at the end of their Lead Time, and recommends replenishment to cover forecasted needs during the following X days - this is your Days of Stock. Set Days of Stock as the frequency of purchasing + any additional buffer (safety stock) that is needed.
Select Variants and use Bulk Actions to adjust Lead Time and Days of Stock for Variants in the Combined Warehouse.
If the purchase order needs to be split once it arrives to the destination warehouse, you can create transfer orders to send stock to another location.
Select the warehouse where stock should be sent in the top left of the Replenishment screen, then set the lead time for that specific location as the time it takes to transfer stock.
