Credit Check failure hold applied on order header, it prevents those shipped lines from invoicing

This is potentially a bug in Oracle functionality. If the product has been shipped, oracle should not stop from invoicing the shippable products. The process should stop only the non-shippable or service products from invoicing.

As some of the order lines shipped and customer is also informed that goods are on the way, they are also expecting invoice at the same time. But because of other lines are under picking release, and orders are credit check hold again, no invoice can be generated. This does not make sense. Credit check hold should not be prevent the shipped lines for invoicing.
