To ensure that you have adequate stock on hand for picking, you can use the replenishment process to fill picking bins from one or more reserve storage types.
In configuration, you can decide, for example, if warehouse tasks should be created, or, if as a first step, only the warehouse request should be created. This internal stock transfer can be used to schedule several replenishment in waves or to plan the execution of replenishment separately from the requirements, for example, replenishment that are only executed at night. Replenishment planning can be done automatically as a regular background job, or you can start the transaction manually and enter all required data.
For each storage type you define the allowed replenishment types. There are four basic methods of replenishment:
- Planned replenishment
- Automatic replenishment
- Order-related replenishment
- Direct replenishment
Note
You will find a fifth replenishment method in Customizing and the replenishment transaction, Crate Part Replenishment. This method is only used for production supply.
Planned Replenishment
You can start planned replenishment interactively or start it in the background.
The system calculates replenishment in accordance with the defined minimum quantity and maximum quantity. Replenishment is triggered when the stock is less than the minimum quantity.
The system rounds down the replenishment quantity (the quantity of the warehouse task or warehouse request) to a multiple of the minimum replenishment quantity, if such a quantity is maintained.
Automatic Replenishment
The system starts automatic replenishment in the background when a warehouse task is confirmed.
The system calculates replenishment in accordance with the maximum and minimum quantity. Replenishment is triggered when the stock is less than the minimum quantity after the confirmation of a picking warehouse task.
The system rounds down the replenishment quantity to a multiple of the minimum replenishment quantity, if such a quantity is maintained.
Order-Related Replenishment
You can start order-related replenishment interactively or start it in the background. The goal in order-related replenishment is to ensure that open outbound deliveries can be fulfilled.
The system calculates the replenishment quantity in accordance with the quantity required on open warehouse requests. Replenishment control is triggered when the stock is less than the required quantity.
The system rounds up the replenishment quantity to a multiple of the minimum replenishment quantity, if such a quantity is maintained. The maximum quantity can be exceeded with replenishment. Even if it can be exceeded, it is necessary to maintain such a maximum quantity.
The Replenishment Level in the storage type must be set on Storage Type Level.
The main feature of the order-related replenishment method is that it takes into account all open warehouse request quantities according your selection.
Note
To use order-related replenishment, it is also necessary to set the Rough Withdrawal Bin Determination in Warehouse Request flag in the warehouse process type used in the warehouse requests.
Direct Replenishment
Direct replenishment is started during a bin denial when an exception code refers to the internal process code Replenishment.
Direct replenishment is only possible in fixed storage bin scenarios. The system calculates the replenishment in accordance with the maximum and minimum quantity. It assumes that the quantity at the storage bin is zero.
The system rounds down the replenishment quantity to a multiple of the minimum replenishment quantity, if such a quantity is maintained.
Direct replenishment can be performed by the warehouse picker (picker-directed replenishment). In this case, a warehouse task for the replenishment displays as the next item to be processed in the picker's warehouse order. As a prerequisite, the system must have found stock in the permitted storage types. Picker-directed replenishment is only possible in radio frequency scenarios.
