If a wave consists of several positions and not all of them could successfully processed (creation of work), positions are not waved anymore an need a re-release to warehouse.

It would be much better that the positions were copied into a new wave, so you can setup a batch job to process the wave.

Scenario:
Loads are planned well before items arrive. Items on stock can be picked in advance. Pending items (e.g. PO items arrive just-in-time) can be picked shortly after they arrived.
