Currently the Bulk Pick option cannot function with orders that contain a product with Special Batch or Serial, whereas if the Auto Pick setting is enabled for all orders it does.
The conflict here can be where portions of orders are needing to be processed in bulk (but not all orders) and the system assumed Batch is sufficient.
It would be great to see an option in settings to be able to ignore this limitation of Special Batch and Bulk Pick to support more business processes.
I agree entirely. We use special batch in order to give flexibility in the batches we send to customers, however this means that we have to individually authorize every pick which is very frustrating.
