Setup:

Items are WMS enabled

Production is done with lean manufacturing

When a kanban is planned for all WMS enabled items a kanban picking wave is generated in order to get kanban picking work.

There is also the possibilty to setup picking activities at a kanban production flow in order to pick the material directly from a defined location.

All items which have a picking activity setup in the production flow for a kanban should not be part of the kanban picking wave because no work is wanted.
