Function documentationVMI Stock in Transit in SAP APO Locate this document in the navigation structure

 

You use this function in a standard VMI process to model the quantity of products that have been issued from the vendor but have not yet arrived at the customer's site. You build stock in transit in the SAP APO system after you have posted a goods issue for the delivery in the SAP ERP system. When the customer receives the products, you have to reduce the stock in transit in the SAP APO system accordingly.

Prerequisites

  • You have not selected the Do Not Build Transit Stock checkbox in the transportation lane master data.

  • You have configured EDI processing in Customizing. For more information, see Customizing for Supply Network Planning under   Advanced Planning and Optimization   Supply Chain Planning   Supply Network Planning (SNP)   Vendor-Managed Inventory   Maintain IDoc Settings for Stock in Transit  .

Features

SAP supports the processing of stock in transit in the following cases:

The Customer Does Not Send Goods Receipt Information to the Vendor

In this case the SAP APO system cannot determine the stock in transit on the basis of information on stock on hand and sales. Therefore, the system assumes that the deliveries arrived at the customer at a delivery date and time before the time of the stock report, and it reduces the stock in transit accordingly.

The Customer Sends the Open Purchase Order Quantity to the Vendor

The SAP APO system calculates the stock quantity on the basis of the open purchase order quantity information, calculating the difference between the open purchase order quantity and the purchase order quantity of published VMI sales orders in SAP APO. From the customer's point of view, this figure is the stock in transit. The vendor uses this information to adjust the stock in transit that has been built in SAP APO at the customer location after posting the goods issue in SAP ERP.

The Customer Sends a Proof of Delivery

The system compares the goods receipt start time contained in the proof of delivery with the delivery date and time of the stock in transit element in SAP APO. It also checks the actual quantity received against the data in SAP APO. If there are any quantity or schedule deviations, the system generates an alert. After the check, the vendor adjusts the corresponding stock in transit in SAP APO using the vendor’s delivery number transferred in the IDoc.

Note Note

If there are multiple SAP ERP systems connected to the SAP APO system, a delivery might be created in different SAP ERP systems with the same number and then sent to the one SAP APO system. In SAP APO, you can use the logical system that created the delivery to differentiate between the deliveries. You can use the FIND_LOGSYS method of the BAdI /SAPAPO/VMI_BADI_TR to assign the logical SAP ERP system that generated the delivery to the vendor number.

End of the note.
The Customer Sends the Stock in Transit Quantity

The following cases may occur:

  • If the customer sends a stock in transit quantity of zero, the vendor deletes the stock in transit of the corresponding product that exists at the customer location in the SAP APO system.

  • If the stock in transit quantity transferred by the customer is smaller than the SAP APO stock in transit quantity, the vendor adjusts the stock in transit quantity in SAP APO to the quantity transferred by the customer.

  • If the stock in transit quantity transferred by the customer is larger than the SAP APO stock in transit quantity, the system generates an alert, and the vendor creates a new order for the additional stock in transit quantity.

  • If the stock in transit quantity transferred by the customer is the same as the quantity in SAP APO, the vendor does not need to make any adjustments.
