Under what condition are cancel orders allowed in SAP Ariba?

In SAP Ariba, cancel orders are permitted primarily when specific conditions are met regarding the integration with Enterprise Resource Planning (ERP) systems and the agreement of the supplier. When the ERP supports cancel orders, it means that the system is designed to handle these requests properly within the procurement workflow. The supplier's agreement is essential as it ensures mutual consent to the cancellation of the order, which is critical in maintaining good supplier relationships and preventing disputes.

In this context, it’s important to note that the efficiency of canceling an order can depend on technical capabilities and the terms established in the purchase agreement. The collaboration between the buyer and the supplier, alongside the support from the ERP system, facilitates seamless order management within the broader procurement process. This approach addresses operational needs and adheres to contractual obligations, hence ensuring both parties are aligned regarding any changes made to the order.

The other options focus on conditions that do not encompass the practical combination of ERP capability and supplier agreement, which are crucial for processing cancellation effectively.
