1. SAP S/4HANA Help Portal: Plant Determination. The official documentation explicitly states the sequence for plant determination: "The system determines the plant according to the following priority rule: 1. It first checks to see whether a plant is specified in the customer-material information record... 2. If no plant is specified there
it checks to see whether a plant is specified in the customer master record of the ship-to party... 3. If no plant is specified there
it takes the plant from the material master record." (Accessed for SAP S/4HANA 2023).

Public Edition 2402 Documentation: Master Data in Sales and Distribution. In the section describing the integration of master data
the plant determination logic is outlined
confirming the hierarchy: Customer-Material Info Record > Ship-to Party Master > Material Master.
