Single-Level Supply and Demand Mapping 

Use

You can use this function before you execute aggregated planning in Supply Network Planning (SNP) to assign receipts that are directly assigned to a location product with a transportation lane to the corresponding demands. You can thus prevent the system from assigning receipts to the wrong demands during aggregated planning, due to detailed information no longer being available at aggregated level.

Single-level mapping means that the system only considers the receipts of one level of the distribution network.

Prerequisites

So that the system can determine the receipts and demands for assignment, it must first delete all stock transfers originating from SNP planning runs. If you leave the default setting on the initial screen unchanged, the system automatically executes this delete operation.

However, you can also specify that you do not want the system to delete the SNP stock transfers for simulation purposes. Then the system can only assign receipts that are new with respect to the previous planning situation.

Features

In SNP planning at aggregated level, the system takes the aggregated receipt and demand situation into account. If the available receipts were not previously assigned to the corresponding demands at sub product level, the system might use the receipt for a specific sub location product to cover the demand for another sub location product. In this case, it does not create a new receipt that could fulfill the demand of the sub location product after disaggregation. It is possible, for example, that the receipt for a red T-shirt would fulfill the demand of a blue T-shirt.

To prevent this, you can carry out single-level assignment of receipts and demands at sub product level before aggregation. The system first checks if the transportation lanes that are directly assigned to the location product have any receipts. Then it creates fixed SNP stock transfers that are considered during the aggregated SNP planning run and cannot be deleted.

Since the assignment is single-level, it may fail if the receipts are not available in the source of supply for external procurement directly assigned to the location product.

Scope of Planning

You can define whether the system carries out the assignment for the products you have entered in all locations or only in selected locations of the network.

Assignment Time Frame

You can define a horizon for the assignment, meaning a time frame in which the system reads the receipts and demands and assigns them to one another. The horizon commences on the start date for assignment.

You can also specify a time offset. Then the horizon begins after this offset, calculated from the start date.

The system does not consider any other horizons, such as the SNP production horizon or the SNP stock transfer horizon.

Aggregation Level

You can define the hierarchy level at which the system carries out the assignment. The system can thus make the assignment at header level or at lower level or at both levels. The standard case, however, is an assignment at sub location product level.

Log

The system automatically creates an application log. The log contains, among other things, detailed information about the processed location products and the fixed SNP stock transfers that were created. For more information, see Application Logs.
