Hello SAP Community,

This is a continuation of my blog series about Replenishment Strategies in SAP S/4HANA Cloud Warehouse Management.

In my previous blog post, I focused on Planned Replenishment. In this blog post, I will focus on Automatic Replenishment and setup an example using fixed bins.

Automatic Replenishment is triggered when the warehouse operative confirms a picking warehouse task that decreases the quantity in the storage bin to below the minimum quantity threshold. The system automatically triggers a replenishment warehouse task creation in the background.

Characteristics of Automatic Replenishment:

  • Calculates replenishment according to existing stocks in the picking area and the minimum and maximum quantities from fix bins or product master

  • It’s only started when the stock figure is lower than the minimum quantity

  • It is triggered automatically upon warehouse task confirmation

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

  • Replenished quantity will not be higher than the maximum quantity

Master Data Setup:

The Master Data Setup is very similar to Planned Replenishment.

1. Activate Replenishment Strategy: Manage Your Solution > Supply Chain > Warehouse Management > Internal Warehouse Processes > Activate Replenishment Strategies in Storage Types


Figure 2. Activate Replenishment Strategies customizing view


2. Assign fixed bins to products: in Assign Fixed Bins app assign fixed storage bins to the product, informing the minimum and maximum quantity for the bin

Note: these maximum and minimum quantities in the fixed bin are solely used for replenishment, it’s not a physical limitation, e.g. I can manually move more than 50 PC to my storage bin below

3. Set Stock Removal Control Indicator: the removal indicator will tell the system where to pick the stock from and what is the removal rule (e.g. FIFO). Please take a look at KBA 3075567 in case you notice your replenishment warehouse task is using the Putaway Control Indicator instead of Stock Removal Control Indicator.

You define it in Manage Product Master Data app > Warehouse Management > Stock Removal

4. Define replenishment quantity in the product master (optional): this setting defines what is the minimum quantity for the replenishment WT, and the min. and max. replenishment quantity in the storage type. For example, if the minimum replenishment quantity is 5 PC the system will not create any task for less than 5 PC and only for multiples of 5 (5, 10, 15, and so on).

You define it in Manage Product Master Data app > Warehouse Management > Warehouse > Storage Type > Replenishment

Procedure:

After the automatic replenishment is customized, the system will automatically create a replenishment WT (in open status) once a picking WT that reduces the stock quantity to less than minimum quantity defined in step 2 is confirmed.

Conclusion

With this process, you can automate the creation of replenishment warehouse tasks to ensure the right inventory levels for your product in the areas where picking is done.

At the end of the process, the warehouse operative confirms the warehouse tasks and makes sure that the stock is moved from the reserve area to the picking area.
