Creating one shipment from one sales order with multiple warehouses

you could consider adjusting your inventory management strategy to consolidate your stock into fewer warehouses. This would simplify the shipping process and allow you to create a single shipment from a sales order with multiple line items.

I understand the challenges of managing inventory across multiple warehouses can be tough, but there are ways to simplify the process. Customizing the shipment process is one such way. You can create a custom shipment screen that consolidates multiple warehouses for each line item in a sales order, based on your business rules. This helps you ensure accurate inventory tracking and avoid stock outs or overstocks. Alternatively, working with an Acumatica developer or consultant experienced in storage warehousing can help you create a custom workflow that meets your needs.
