What level can supplier managed inventory business transaction rules be set to?

Supplier Managed Inventory (SMI) business transaction rules in SAP Business Network can be configured at:

Supplier level- Specific rules for individual suppliers.

Supplier group level- Rules applicable to a group of suppliers that share common characteristics or business requirements.

This granularity allows buyers to effectively manage collaboration and inventory policies depending on the supplier's role in the supply chain.
