An inbound document states what you expect to receive.
- Go to Inbound › Inbound documents › New.
- Select the supplier and the warehouse.
- Add the products with their expected quantity.
- Save and assign the receipt to an operator (or leave it in the work pool).
Documents also arrive from your ERP through the API or through the connectors for SAP, Odoo, Microsoft Dynamics 365 Business Central or ERPNext.
