A kit is a list of products that are always delivered together. Examples of kits include the following entities:
Groups of materials used to repair a piece of machinery.
Groups of materials used for assembly tasks.
Add-on products for other products.
Displays or assortments of products to sell in a retail store.
SAP Extended Warehouse Management does not save kits as master data. Instead, it receives information about the structure of a kit in the form of outbound delivery items from the SAP ERP system. The structure containing the kit in the outbound delivery along with a packaging specification, is used as a basis for assembling or producing a kit in SAP EWM.
A kit can consist of the following levels:
Kit header, which represents the finished kit.
Kit component, which represents a product in the kit.
SAP EWM does not support "nested kits" (which are kits within kits).
"Kitting" is the process of building or assembling kits. SAP EWM supports kit-to-order and kit-to-stock processes.
In the kit-to-order process, each kit is assembled based on a customer order. This is similar to a make-to-order manufacturing process. To support sales of pre-assembled kits, SAP EWM also provides a kit-to-stock process in which kits are pre-assembled and placed into stock.
Kitting Process
Although SAP EWM supports the kitting processes, there is no master data such as a bill-of-material (BOM) stored in SAP EWM. The kit is represented as a hierarchy of items of an outbound delivery order. In kit-to-stock, SAP EWM can reference a BOM stored in the ERP system.
The following rules apply to kits:
A kit is always delivered in full to a customer.
The kit header and kit components are always scheduled for the same date.
All components for the kit must come from the same warehouse.
Kit prices are always calculated at the header level.
A kit header and the kit components have a quantity ratio to each other. This is defined by the kit structure.
Kit-to-Order Process Steps
The kit-to-order process, in its simplest form, consists of the following steps:
A sales order is created for the kit header in SAP CRM or in SAP ERP.
SAP EWM creates a warehouse request (outbound delivery order). This process triggers the kit-to-order process.
The kit components are picked and assembled into the finished kits.
The system confirms the delivery and the goods issue is posted for the kits.
The sales order is updated and the billing is triggered for the order.
Kit-to-order processing can be performed using a VAS Order and a corresponding work center, or it can be performed as part of the picking process.
Kit-to-Stock Process
The process of creating kits and then transferring them to stock is executed and documented in the warehouse. You can either trigger kit creation manually in the ERP system based on a production order or in the SAP EWM system directly, using a VAS order.
You can also perform reverse kitting, which splits a kit back into its components.
Summary
Value-added services (VAS) are controlled by SAP EWM via the VAS order (created via a a packaging specification with specific characteristics).
A VAS order contains an order header, a list of VAS activities, items, and auxiliary products (for example, packaging materials, straps, and labels) and can be created manually or automatically.
- VAS can also be used for kitting. A kit is a fixed set of components delivered together and in SAP EWM is represented by outbound delivery item hierarchies rather than stored master data. Kits can be produced for orders ()KITO) or for stock (KISO).
