A MTCR,
Sourcing change for nut square as VA item QA will direct contact to Yahata supplier and then will make appointment with supplier to conduct QSES Audit,
But about sourcing change for Collar as VA item EAT direct buy to Proten supplier, that mean EAT must confirm part and process by themselves,
For part and process confirmation, if EAT need SCAL confirm together, please make clear about schedule,
