 Simulation and Adjustment of Stock in Transit

Use

If the transit time is the same as or longer than the length of the replenishment cycle, replenishment planning must also consider stock in transit. Since you, as supplier, do the planning for the customer in the Responsive Replenishment scenario, you do not have access to customer figures for stock in transit. The data import controller therefore simulates the stock in transit on the basis of replenishment orders.

The data import controller also compares data sent by the customer for replenishment orders and stock with the stock in transport that it simulated from the replenishment orders in the SAP Supply Network Collaboration (SAP SNC). If there are deviations, the data import controller corrects the stock in transit in SAP SNC.

SAP SNC uses the stock in transit to calculate net demands that you require in replenishment planning and in the Transport Load Builder.

Features

From the customer view, the stock in transit is the difference between the open order quantity in the customer system and the replenishment order quantity of the published replenishment orders in SAP SNC. From the supplier view, the stock in transit is the sum of all replenishment orders for a location product that the supplier in SAP SNC publishes:

Sum of all replenishment orders = Initial stock in transit

If the customer receives further XML messages about replenishment orders, the replenishment order stock increases accordingly:

Sum of all replenishment orders = Stock in transit at time i

The data import controller must reduce the stock in transit by the quantities for which the customer has posted a goods receipt. Since the data import controller cannot access goods receipt postings in the customer system, it calculates the goods receipts on the basis of the data in the customer XML messages. This data can be:

  • Stock and sales

  • Open order quantity

Customer Sends Only Stock/Sales via EDI/XML

With information about stock and sales only, it is not possible to determine a goods receipt and this the stock in transit in SAP SNC from the customer view . For this reason the data import controller simulates the stock in transit as the sum of the published replenishment orders for a location product, but it does not make any further adjustments based on the customer data in XML messages. Instead, the data import controller presumes that the replenishment orders arrived at the customer with a delivery date/time before the stock report. The data import controller automatically sets these TLB transports to zero.

Customer Sends Open Order Quantity via EDI/XML

For the stock in transit in SAP SNC, the data import controller reduces the sum of all replenishment orders by the goods receipt quantity of an arrived replenishment order when the arrival date of the replenishment order has been reached. In doing so, it has simulated a stock in transit that it can now compare with the stock in transit from the customer view.

If the customer sends open order quantities in XML messages to the supplier, the data import controller can also simulate goods receipts and thus stock in transit from the customer view .
