What is the logic for reservations/allocations for work orders in EBS?

Lets say I have 10 work orders 1 for each of the following days. each of them requires 1 unit of certain material, which i only have 5 available in stock.

When I release the work orders at the same time, which 5 work orders will have the priority to allocate the material?(preventive work orders are configured to automatically allocate materials when released).

Expected behavior should be that closer work orders (in terms of programmed dates) should be the one reserving first.

Current behavior: Work orders allocate randomly, so i end up having 0 items allocated for the work order programed for tomorrow and material correctly allocated for the work order programmed in 10 days.
