Which objects can be used as a reference when dependent characteristics specifications are created?

Dependent characteristic specifications in SAP QM allow characteristics in an inspection plan to inherit values (e.g., tolerances) from a reference object. This is configured in the inspection plan (transaction QP01) under characteristic details:

Material and Customer (C): Used in sales-related inspections (e.g., inspection type 10), this reference allows characteristics to be tailored to customer-specific materialrequirements, pulling data from the material master or customer info records.

Material and Supplier (D): Common in procurement (e.g., inspection type 01), this reference links to quality info records or material master data, enabling supplier-specific specs for a material.

Material (E): The material alone can serve as a reference, pulling general specifications from the material master (e.g., QM view) or material specifications (transaction QS61), applicable across scenarios.

Material and Control Key (A): Control keys define operation behavior, not characteristic specifications, so this is not a valid reference.

Material and Work Center (B): Work centers are operation-specific and don’t store characteristic specs for reference in standard SAP.

Thus, "Material and customer," "Material and supplier," and "Material" are the correct answers.References: SAP Help Portal - "Dependent Characteristic Specifications"; SAP S/4HANA QM User Guide - "Inspection Planning".
