  Item is picked even if the subinventory is set to other and qty is not enough and can ship confirmed
Problem Description
---------------------------------------------------
this is PROD

shipping parameter setting - autoallocate default stg subinventory > NRL

subinventory setting NRL reservable, SSR non reservable

qty in NRL 10, qty in SSR 8

sales order order 10 qty set subinventory to SSR

release sales order inventory all set to SSR
10 item is picked even qty is 8 in SSR, and no partially picked, after ship confirm, interface trip stop stuck will occur later saying -negative balance

this is TESTING
same setting
but when release sales order all qty is picked , after ship confirm, qty is reduce in NRL instead of SSR
