Applying Replenishment Methods

Objective

After completing this lesson, you will be able to examine replenishment methods in SAP EWM

Replenishment

Note

See the following video to learn more about replenishment processes in SAP EWM:

Note

The replenishment technique to be used is assigned to a storage type in Customizing. Some of the replenishment control types require additional configuration settings.

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 control 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.

A line graph illustrating the stock levels with maximum and minimum quantities marked. Two horizontal lines denote Maximum Quantity at the top and Minimum Quantity at the bottom. A stepped blue line represents the stock level, beginning at the Minimum Quantity, rising to below Maximum Quantity, and then dropping. An orange dashed vertical line indicates the replenishment trigger when stock falls below the Minimum Quantity. Accompanying text explains that replenishment is started in online or batch mode, calculated according to maximum and minimum quantities, initiated when stock is lower than minimum quantity, and rounded down to multiples of minimum replenishment quantity.

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 control is triggered when the stock is less than the minimum quantity.

The system rounds down the replenishment quantity to a multiple of the minimum replenishment quantity.

An image shows a graph and a set of bullet points. The graph features a vertical line divided into segments representing maximum and minimum quantities. A black horizontal bar indicates the top portion as the maximum quantity, while a blue and orange vertical segment showcases changes in quantity, starting from a point above the minimum quantity level and dropping below it. The dashed orange vertical line represents the point where replenishment processes begin once stock falls below the minimum quantity threshold. To the right of the graph, four bullet points summarize the replenishment methodology: 1) Started during WT Confirmation, 2) Calculates Replenishment according to Maximum and Minimum Quantity, 3) Only Started when Stock figure gets lower than the Minimum Quantity, 4) Round down to Multiples of Minimum Replenishment Quantity.

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 the selected outbound delivery orders 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. The maximum quantity can be exceeded with replenishment.

A graph displays stock replenishment data with three horizontal lines indicating different quantity levels: Open WHR Quantity, Maximum Quantity, and Actual Quantity. A dashed orange vertical arrow starts at the Actual Quantity level and surpasses the Maximum Quantity level, stopping just below the Open WHR Quantity level. To the right, text notes five key points related to the replenishment process: 1) It can start in either online or batch mode. 2) Replenishment is calculated based on open WHR quantity. 3) The process begins when stock figures fall below the required quantity. 4) The quantity is rounded up to multiples of minimum replenishment quantity. 5) Exceeding the maximum quantity is possible.

Direct Replenishment

Direct replenishment is started during a bin denial, that is, 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.

Direct replenishment can be performed by the warehouse picker (picker-directed replenishment). In that 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.

Diagram showing the process of replenishment in a warehouse. On the left, a graph illustrates a quantity flow, with two horizontal lines marked as Maximum Quantity at the top and Minimum Quantity at the bottom. A jagged arrow labeled Exception REPL points downwards towards the Minimum Quantity line. The graph indicates that replenishment starts during a pick denial when the exception code points to the internal process code Replenishment. It is only possible for fixed bin scenarios and is calculated according to Maximum and Minimum Quantity assuming the bin quantity is zero. The process rounds down to multiples of Minimum Replenishment Quantity. Picker performs the replenishment, labeled as Picker Directed Replenishment.

Summary

Replenishment within SAP EWM is used to provide stock from other storage types within the warehouse to a specific storage type where the stock is needed (e. g. storage type for picking goods).
Different replenishment methods support the correct replenishment strategy for your warehouse.
