Use
When using the Multi-Step Replenishment application component, you can manage inventory in one of two ways:
In this case Replenishment is based on the Inventory Management data from Materials Management of the SAP R/3 System. Each goods movement is recorded in a document. You should use this type of Inventory Management as much as possible. It can, however, only be used for Replenishment if you manage stocks on an exact article basis (not on a merchandise category basis).
You can also use Replenishment-based Inventory Management with Multi-Step Replenishment. You activate replenishment-based Inventory Management by selecting the indicator in the replenishment article data for the article destined for the relevant store. Note that you can only use multi-step replenishment for stores.
Replenishment-based Inventory Management allows you to replenish stocks of articles managed in MM-based Inventory Management on a merchandise category basis (value-only article).
In Inventory Management with Multi-Step Replenishment, inventory is managed in a much simpler way than in Materials Management. The only figure relevant to Replenishment for a particular article at a particular store is the stock on-hand. No goods movements documents are kept.
The following transactions/events can change replenishment stock:
