Reverse Kitting 
Purpose
You can use this process to split kits up into their components. You start the process by creating a VAS order for reverse kitting manually. You can start this process in the EWM system only.
Prerequisites
The following prerequisites must be fulfilled in the EWM system:
- You have defined a VAS order type for reverse kitting.
- You have defined document types for the inbound delivery and for the outbound delivery order, which are intended for the Reverse Kitting process. These document types are assigned to the VAS order type.
- You have defined item types for the inbound delivery and for the outbound delivery order. These item types are valid for the document types mentioned previously, and are assigned to the VAS order type.
- A packaging specification exists for the kit product.
- Optional: A bill of materials in the ERP system exists for the kit product.
Process
1. You create the VAS order manually.
You can either create the VAS order with or without a bill of material:
If you create a VAS order with a bill of material, the system attempts to find and explode a bill of material in the ERP system for the kit product.
The system automatically determines the quantities of the kit components using the number of kits that you want to create.
If you create a VAS order without a bill of material, you must specify the kit components manually, as well as the kit product.
You can configure the system so that it performs an availability check for the kit. For more information, see Availability Check. If the system is unable to confirm the kit completely, it reduces the quantities of components and kit quantities automatically.
2. The EWM system generates an outbound delivery for the kit header, and an inbound delivery for the kit components.
3. The EWM system transfers both deliveries to the ERP system. Serializing the messages to the EWM system is done based on the document number of the ERP outbound delivery. All confirmations from the EWM system to the ERP system are serialized based on the document number of the ERP outbound delivery.
The system does not generate an outbound delivery request or an inbound delivery notification.
4. The EWM system generates the document number of the VAS order in the form of a document flow entry for all items of the inbound delivery and outbound delivery order.
The process flow of the VAS order is the same as that of the VAS order for the Kit to Stock process. For more information about the process flow for a VAS order, see Kit Creation Using a VAS Order.
The following restrictions are valid for reverse kitting:
The VAS order can have one activity only. If a packaging specification has other levels apart from the kitting level, the system des not consider the other levels.
By confirming goods issue of the kit and goods receipt of the kit components, goods issue and goods receipt are automatically confirmed to the ERP system.
Result
Based on the VAS order, you can execute and document the process in the EWM system. You can also process deliveries in the delivery transactions. However, only basic functions such as posting goods movements are available.
