Requirement for auto split the line

Summary:

I have 3 different sales order and quantities with no on hand available.

Item 33015498

SO 12345 Qty 200 SSD May 2

SO 85698 Qty 100 SSD May 4

SO 25478 Qty 50 SSD May 7

If I receive 150 quantity warehouse,

Expectation is that this quantity reserves to SO 12345 for 150 of the 200 required pcs. The line would then auto split, and allow us to ship the 150 pcs

What we are seeing today, is regardless of the SSD, if available quantity is larger than demand quantity regardless of being the oldest order, it is looking at the next available order to reserve fully against
