Hi,
I think, Package ZBI_NEW  is a custom development package: probably someone else already transported the application component hierarchy and assigned this package...try to change this. Chk with SE80 > package > ZBI_NEW,If it is not there,create it.
But the normal practice is change/Edit DSO in DEV-->Quality , then transport to Production.(SE80
In the drop down, look for Packages,below it type ZBI_* and hit Open.If you don't see ZBI_NEW, then ask BASIS to Create (DEV)and import that Package to QAS->Production)
