Message type: E = Error
Message class:  VO - W&S: Rough workload forecast + picking wave 
Message number: 066
Message text: Delivery &1 was not transferred to wave &2 for capacity reasons
Wave picks were created in a background job. The system could not assign
delivery &V1& to the wave pick &V2&, because a capacity limit had
already been exceeded.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
You can carry out the following activities:
Create a new wave pick for the remaining deliveries.
If you want to include delivery &V1& in a wave pick, despite the
violation of the capacity limitations, delete the wave pick &V2&.
Now create a new wave pick and select the processing type "Display waves
before saving".
You can now add the deliveries rejected due to capacity restrictions to
the wave pick.
If necessary, check the settings for the capacity restrictions in
Customizing for wave pick profiles.

Cause: This error occurs in the Warehouse Management (WM) or Extended Warehouse Management (EWM) module during the wave creation or wave release process.

In other words: The wave or the resources involved in the wave (like picking areas, work centers, or handling units) have a capacity restriction, and adding this delivery would exceed that capacity. Therefore, the system blocks the transfer of the delivery to the wave. Common Causes: Capacity restrictions set in the wave template or wave profile: The wave has a maximum capacity (e.g., number of deliveries, weight, volume, or number of handling units) that cannot
