Purpose

Replenishment planning calculates replenishment requirements and then generates follow-on documents for procurement and delivery. Planning results will be displayed in the replenishment monitor. Here you can see which follow-on documents have been created and which errors have occurred. You have the option of carrying out replenishment planning in the system online or as a job.

In replenishment planning, the system differentiates between the following situations:

For more information about the differences between these two scenarios, see Replenishment.

Prerequisites

If you want to update stock information for replenishment using POS inbound processing, you must have completed processing before beginning replenishment planning.

Process Flow

  1. You can start replenishment planning manually (online) or in the background (in batch) for selected recipients and articles.
  2. The system calculates expected stock at recipient at the end of the replenishment lead time.

    3. If forecast data exists in the system, you can take the forecasted sales until the end of the replenishment lead time into consideration (see also Replenishment: Forecasts).

    If Inventory Management in Materials Management is active, planned store issues and receipts until the end of the replenishment lead time can be taken into consideration using ATP (see also Replenishment: Inclusion of Expected Receipts and Issues).

  3. The system calculates target stock.

    4. Target stock can be calculated using replenishment article data (static target stock) or dynamically when replenishment planning is carried out (dynamic target stock). You can only work with dynamic target stock if forecasted sales data exists (see also Replenishment: Example of Planning Using a Dynamic Target Stock).

  4. The system calculates your required replenishment quantity.

    5. The required replenishment quantity is the difference between the target stock and the standard stock. If you have maintained a reorder point, a required replenishment quantity is only defined if the reorder point has not been exceeded (see also Replenishment: Using a Reorder Point).

    If, while planning replenishments, requirements are determined for components of structured articles, the system converts the requirement to that for the header article. You can then enter the header article in the follow-on documents. If required, you can influence how the system converts the component requirements to header article requirements via a user exit (see also Replenishment: Structured Articles).

  5. In manual replenishment planning, you can correct required replenishment quantities manually.

    6. In online replenishment planning, the articles to be included in the replenishment run are displayed before follow-on documents can be generated. Data is displayed using the ABAP List Viewer that enables you to, for example, filter or sort the data. Here you can also view the required replenishment quantity for every article - you can change the quantity manually (for example, for test purposes). You can view a detailed screen for every item which shows how required quantities are defined.

  6. Follow-on documents are generated.

After requirements have been determined, follow-on documents are generated. You have to start this program manually on the screen for displaying requirements. The system uses functions for store order processing to generate follow-on documents (see also Store Orders). You can generate the following documents:

If no site master data exists for a recipient, a sales order is normally generated (order type TAV). The system generates follow-on documents and optimizes the quantities required. The replenishment quantity is the requirement quantity after it has been rounded off (see also Order Optimizing: Quantity Optimizing).

You can generate follow-on documents in a test mode. Follow-on documents are only generated internally in test modes without data being written to the database. The results from replenishment runs can be evaluated both in normal mode and test mode, using the replenishment monitor.

Results

If no errors are recorded, follow-on documents are generated for Replenishment. Each time you execute the program for planning replenishments, the system stores the replenishment run under an internal number. This number is used to identify a transaction when you subsequently analyze the run in the replenishment monitor. For further information, see Replenishment Monitor.
