In Inventory Allocation, for the first 3 lines the Action Column is ‘Release to Logistics’. If you select Proceed, the three lines will be released you can add them to a delivery and ship/invoice
The other line has ‘none available’ (meaning there is no inventory available) so for this line, the Action Column displays ‘Do Not Process’. If you select ‘Proceed’ this line will remain unallocated and you will be able to release it when the product is available at a future date
