Supply Allocation feature & “Do Not Allocate”

When the Supply Allocation feature is enabled “DO NOT ALLOCATE” showcases the same functionality of “Do not Commit” in Sales Order. By setting “DO NOT ALLOCATE” in back-ordered item lines, whenever stock comes in the future it won’t get committed in these Back-ordered lines.
