OFBiz Shipment operations too buggy to use?

[Christian Carlow]

I was wondering if anyone could tell me whether or not OFBiz's shipment 
capabilities are sophisticated enough to work OOTB or if its considered 
something too buggy to use yet.  I've tried creating shipments to 
fulfill OrderItem ShipGroup schedules multiple ways and have encountered 
bugs with all of them.  The majority of the bugs relate to incorrect 
calculation of the OrderItemShipGroupInvRes. OrderItemShipGroupInvRes 
seems to determine what is allowed to be picked, packed and shipped but 
can easily contain incorrect information.

I tried disabling the Reserve Inventory option of the store but this 
prevented me from shipping anything.  Does Reserve Inventory have to be 
enabled to allow shipment capabilities for orders?

Is anyone using OFBiz OOTB to handle order shipments?
