Aggregation Level

The replenishment service plans on the level of the following characteristics:

Products Relevant for Replenishment Planning

The replenishment service only executes a replenishment planning for a customer location product if the location product status of the customer location product allows it. For customer location products with the status Inactive or Discontinued, the replenishment service does not execute a replenishment planning. For more information, see Location Product Status.

Product Determination

SAP SNC can use the supplier back-end product when communicating with the supplier back-end system. Data in the XML messages is therefore based on the supplier back-end product. Upon receipt of an XML message, SAP SNC executes product determination and thereby determines the planning product, in other words, the product for which you are executing the replenishment planning in SAP SNC. When the supplier sends a replenishment order to the supplier back-end system, the system again executes a product determination for the outbound XML message, to determine the supplier back-end product. For more information, see Use of Supplier Back-End Products and Products.

Planning Horizon

The replenishment service executes the replenishment planning for the planning horizon. You can define the start and the duration of the planning horizon as follows:

In the replenishment monitors, the replenishment service uses the following planning horizon:

Processing of Existing Planned Receipts

You can make settings so that the replenishment service first deletes the existing planned receipts before it creates a new planning. To do this, you select the Clear Planned Receipts checkbox. If you do not select this checkbox, the replenishment service function does not delete the existing planned receipts. This has the following consequences: When the projected stock in a period falls below the reorder point, the replenishment service increases the existing planned receipt in this period accordingly, to reach the target stock. If, as a result, the projected stock exceeds the maximum stock level in the subsequent period, the function does not reduce the planned receipt in this subsequent period. If you do set the indicator, you can avoid such surplus.

You select the checkbox in Customizing for Supply Network Collaboration under  Replenishment Replenishment Planning Assign Settings Assign Settings for Replenishment Planning and SNI . For the SMI Monitor and the Min/Max Replenishment Monitor, you can also select the checkbox on the Web user interface (Web UI) in the monitor settings. For more information, see Example: Clearing Planned Receipts.

Processing of Unpublished TLB Shipments and Replenishment Orders

In the standard system, the replenishment service deletes unpublished TLB shipments and the assigned replenishment orders at the beginning of the planning run. You can configure the replenishment service profile so that the replenishment service does not delete these objects.

Sourcing

The replenishment services uses sourcing to determine the following data:

The following sourcing methods are available:

For more information, see Sourcing.

Calculation of the Projected Stock

For the replenishment service to be able to calculate the raw net demand of a period, it must first calculate the projected stock. You configure how the replenishment service calculates the projected stock in Customizing for Supply Network Collaboration. For more information, see Calculation of Projected Stock.

Calculation of Raw Net Demand

The raw net demand represents the unrounded net demand of the customer location product in a period. The raw net demand is the demand that the supplier must actually cover with planned receipts. In the raw net demand, the system - contrary to the gross demand - considers the existing stocks and receipts. The raw net demand is the basis for calculating the planned receipts: The replenishment service determines the quantity of the planned receipt by rounding the demand quantity up or down. For more information, see Calculation of Raw Net Demand.

Scheduling of Planned Receipts

A planned receipt for a raw net demand must occur as punctually as possible. The dates/times for the outbound and inbound delivery must agree with the calendars and execution times for all delivery-relevant activities on the supplier side and customer side. To determine these dates/times, the replenishment services conducts a scheduling. Depending on the calendars and the execution times, a planned receipt can occur before or after the actual demand period. For more information, see Scheduling of Planned Receipts.

Calculation of the Planned Receipt Quantity

To cover the raw net demand as punctually as possible, the scheduling (see above) creates a planned receipt for a particular raw net demand on a date/time that lies in or as close as possible to the demand period. In doing so, the system takes into account the relevant calendars and execution times. In this way, the planned receipts for different raw net demands can come together in a period. The replenishment service groups these quantities together into one planned receipt. In addition, the replenishment service now applies different restrictions for the receipt quantity: It rounds the receipt quantity according to the rounding settings in the master data. In an SCM server installation, the replenishment service can also consider product allocations. For more information, see Rounding Using One Rounding Value, Two-Level Rounding, and Consideration of Product Allocations.

Saving of Planned Receipts

You can configure whether the replenishment planning saves planned receipts as time series in Time Series Data Management (TSDM) or as planned replenishment orders (order document type DRPV) in Order Document Management (ODM). In the Supplier Managed Inventory business scenario, for example, you use time series; in the Responsive Replenishment business scenario, you use planned replenishment orders. Thus, depending on your settings, the key figure Planned Receipts represents time series data or planned replenishment orders.

Update of the "Planned Receipts" Key Figure

When advanced shipping notifications (ASNs) and replenishment orders are published, the system also updates the key figure Planned Receipts based on the formula used for the projected stock. For more information, see Update of the "Planned Receipts" Key Figure.

Overview: Objects Created by Replenishment Service

The replenishment service creates the following objects and updates the corresponding key figures:
