The control cycle is the master data object that governs the relationship between supply source and demand source in the Kanban process. The control cycle defines the following data for Kanban production:

The number of Kanban containers and the quantity per container or per call item

The basic data required for automatic Kanban calculation, if necessary

The replenishment strategy, which determines how the supply source replenishes the demand source, such as in-house production, external procurement, stock transfer, or assembly

The print control, which determines how the Kanban cards are printed, if necessary

The delivery address, which determines where the Kanban containers are delivered, if necessary

The process control, which determines the status sequence, the goods movement, the packing instruction, and the production call profile, if necessary1

The control cycle is created and maintained using the app Manage Kanban Control Cycles or the transaction PKMC. The control cycle is assigned to a material and a plant, and can be split into different segments for different supply sources or demand sources2.

The other options are not correct for the following reasons:

Replenishment strategy (A): This is not a master data object, but a field in the control cycle that specifies the type of replenishment for the Kanban process. The replenishment strategy can be in-house production, external procurement, stock transfer, or assembly1.

Production supply area (B): This is a master data object that represents a physical or logical area where materials are supplied for production. A production supply area can be assigned to a material, a work center, or a production line. A production supply area is not directly related to the Kanban process, but it can be used to group materials or work centers for planning or reporting purposes3.

Rate routing (D): This is a master data object that defines the sequence of operations and the work centers for producing a material in repetitive manufacturing. A rate routing canbe assigned to a material and a production version. A rate routing is not directly related to the Kanban process, but it can be used to calculate the production rate and the lead time for in-house production.
