IDoc for Releasing Waves 
The IDoc /SCWM/WMRRID01 is used to release transfer orders for a wave pick that have already been sent to a non-SAP system. The system sends the group number to the header data of the warehouse task to be created.
Prerequistes
You have transferred the wave number to the non-SAP system using IDoc /SCWM/WMTOID01 in segment /SCWM/E1LTORHI for the WTs that have been grouped together into waves.
Features
You group together the warehouse tasks into a wave so that you can execute the goods movements for these WTs in one step. For example, processing warehouse tasks for a certain shipping point or removing stock in the same interim storage type. In this case, you are not permitted to execute the goods movement immediately after the non-SAP system receives the warehouse task data. You use the IDoc /SCWM/WMRRID01 to trigger the start of the stock movements for a certain wave by releasing the wave.
