In the Supplier Managed Inventory (SMI) process within SAP Ariba Supply Chain Collaboration, releasing a schedule line converts a forecast or planned requirement into a firm commitment for the supplier. This action directly updates the "Firmed Order" key figure on the SMI detail screen. This key figure represents the quantity of items that the buyer has formally committed to purchasing but which have not yet been shipped by the supplier. It serves as a clear signal to the supplier to prepare for fulfillment.

A. In-transit: This key figure is updated only after the supplier has shipped the goods and submitted an Advanced Shipping Notice (ASN), not when the order is initially released.

B. ASN Received: This is updated upon the buyer's system receiving the ASN from the supplier, which occurs post-shipment and is a subsequent step to the order release.

D. Goods Received: This key figure is updated at the final stage of the process, when the buyer physically receives the items and posts a goods receipt confirmation.

1. SAP Ariba Documentation: Product-based forecasting and inventory collaboration guide. In the section "Supplier managed inventory

" the process flow and key figures are detailed. It specifies that "Firmed Order" represents the quantity the buyer has committed to ordering

which corresponds to a released schedule line. The "In Transit" quantity is explicitly linked to the creation of an ASN by the supplier. (Accessed via SAP Help Portal for SAP Ariba Supply Chain Collaboration).

2. SAP Learning Hub Courseware: CARSCC2404 - SAP Ariba Supply Chain Collaboration. Unit on "Inventory Collaboration

" Lesson on "Supplier Managed Inventory." The learning material explains that the SMI dashboard tracks various inventory statuses. The "Firmed Order" metric is defined as the quantity confirmed by the buyer via mechanisms like scheduling agreement releases

while "In-transit" is populated by ASN data.
