Current design:

After initial release to warehouse after performing batch balancing process, there is no way to add additional formula lines/components to the batch order as the work for it will not be created and will result in the below error:

"Batch order %1 was not released to warehouse because the batch order is part of the batch balancing process."

Suggested design:

It should be allowed to release additional lines especially of the type "none" as they do not affect the batch balancing process calculation and it is a common scenario in many industries where replacement for fragile components could be needed to proceed with the production process.
