Rapid Replenishment

Rapid replenishment

Replenishment is a procedure for the demand-oriented supply of goods to the Outlets. This handout shows the complete replenishment process. The replenishment process consists of the following steps.

  1. sales in the store
  2. Stock transport order
  3. Replenishment planning
  4. Process delivery
  5. Goods receipt in the store

 

To ensure that the replenishment process can be carried out correctly, you must ensure that the correct replenishment type is entered in the article master for the planned store. We can check this using transaction MM42 in the Logistics Store view in the MRP type field.

The following replenishment types are important for SAP Retail.

·         – RP (Replenishment)

·         – RF (Replenishment with dynamic target stock)

·         – RS (rhythmic replenishment)

·         – RR (rhythmic replenishment with dynamic target stock)

MRP type view: Logistics store

The target stock is also entered in this view. The target stock is the stock that is to be planned for the store in replenishment planning.

Replenishment parameters

The “target stock” is entered in the fields for the replenishment parameters. This is the number of collies that are planned to be available in the outlet store. If the target stock field is filled with values, you enter manually how much stock should be available in the store or site. You can switch to dynamic replenishment planning by setting the forecast indicator “RF” or “RR”. If dynamic replenishment planning has been activated, the fields Min. target stock and Max. target stock are displayed. Target stock are used. This limits the maximum stock value and the minimum stock value. The forecast values provide a value that lies within these parameters. The minimum target stock value limits the value downwards and the maximum target stock value limits the value upwards. In SAP Retail, the target range of coverage field contains the number of days for which the stock is sufficient. This is based on the forecast and the expected goods receipts.

 

Forecast

The basis of reorder point planning is the comparison of the stock available for planning with the reorder level. If the available stock is less than the reorder point, procurement is triggered. If a vendor always delivers an article on a certain day of the week, it makes sense to plan the article in the same frequency. For this purpose, the RP type Rhythmic planning and the planning frequency are entered in the article master record. The planning frequency is entered in the form of a planning calendar.

If the system is configured to use one of the forecast models, the system can access the number of the last purchase orders for a colli or all collies (individual or total forecast). The average value of the number of goods ordered is then the number of goods ordered in the future.

The following models can be used for the forecast:

·         Constant model (Here there is a constant course of consumption, which fluctuates statically)

·         Trend model (Over a longer period of time, consumption increases or decreases with random fluctuations).

·         Seasonal model (deviations from the basic value occur regularly at periodic intervals).

 

·         Seasonal trend model (seasonal deviations around a constant average occur).

 

 

The supplying distribution center must, of course, have sufficient stock in hand. Transaction RWBE can be used to check how much stock the store currently has as a receiving plant. However, the distribution center, as the sending plant, can also be monitored in terms of stock.

 

Stock overview By double-clicking on the stock type, you can also display stock in transit, for example.

 

In our example, we want to ensure that we have sufficient stock in our distribution centre. Therefore, we use transaction MIGO (Goods Receipt/Other) to manually increase the stock to the desired level using movement type 561. We can use the formula to calculate requirements: GR date = planning date + planned delivery time

Calculation:

In the example shown here, the goods receipt date is the result of adding the goods receipt date and the planned delivery time. (Sundays and holidays according to the factory calendar are counted as working days).

 

Minimum, maximum and target stock

The system calculates the stocks for the corresponding time period using the following formulas:

– Minimum stock: average daily requirements * minimum range of coverage

– Target stock (= dynamic safety stock): average daily requirements * target range of coverage

– Maximum stock: average daily requirements * maximum range of coverage

 

You can use transaction WR60, Replenishment Parameter Overview, to check whether the article can be procured. Transaction WPUK can be used to simulate sales in the store. After entering the customer and the required transaction date, you can choose between the following sales types: sales as per receipts, summarized sales, means of payment, and cashier statistics. See Figure 4.

Cash Register Simulation

 

Of course, planned goods receipts are also taken into account in replenishment planning. Stock transport orders (using TO ME27) can be used if you want to close assortment gaps manually, for example.

Once everything is set up, replenishment planning can be carried out. Once the follow-on documents have been generated, the purchase order is created. You can either plan replenishments online or schedule them manually as a job and run them automatically.

Now we come to the actual replenishment run. You start this with transaction WRP1 in the SAP system. Make entries in the fields Recipient (store ID or site), Article and Planning date. Check whether the checkboxes for receipts/issues via ATP are to be determined, forec. Include forecast issues and Net change procedure are set. (The switch Determine receipts/issues using ATP ensures that an availability check is carried out for the desired article in the store at the time “end of replenishment lead time”. If the checkbox Net change procedure is set, this means that only articles for which replenishment-relevant changes have taken place since the last requirements calculation are taken into account for requirements authorization).

Choose Replenishment planning when the run is complete. From the menu bar, choose Replenishment requirements -> Generate follow-on documents. The purchase orders are then generated after everything in the system. In the following window, you can select the Replenishment Monitor and view the result of the planning run. Here you can see an overview of the store to be supplied and the generated purchase order number. By double-clicking on the purchase order number, you can branch directly to the purchase order and change the items within the purchase order.
