You can reverse the consolidation process using the un-consolidate option.
To un-consolidate orders:
Select Facility > Warehouse > Wave > Execution > Maintain Waves. The Wave Maintenance screen is displayed.
Select a record.
Click Function > Unconsolidate.
To confirm, click Yes.
After you select this option, the application removes the assignment of all the wave items that were assigned during the consolidation process from the speed pick locations.
