Use
When using the 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. 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 activate replenishment-based Inventory Management by selecting the indicator in the replenishment article data for the article destined for the relevant recipient.
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). With replenishment-based Inventory Management, you can manage stocks for external customers for which there is no MM-based Inventory Management data.
In replenishment-based Inventory Management, 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 recipient is the stock on-hand. No goods movements documents are kept.
The following transactions/events can change replenishment stock:
