When a quality certificate is mandatory (set in the quality info record, transaction QI01) but no GR inspection lot is created (inspection type 01 inactive in the material master), the system handles the missing certificate as follows:
* The Goods Receipt is Posted to Blocked Stock (B): If the certificate is required (e.g., "Certificate Check" active in QI01) and not received (transaction QC55), the GR (transaction MIGO) posts the material to blocked stock (movement type 103/105 process). This is standard behavior to prevent unrestricted use until the certificate is confirmed, even without an inspection lot (SPRO > QM > Quality Certificates > Procurement > DefineControl Keys).
* Unrestricted Use Stock (A): This would occur only if no certificate check was enforced, contradicting the premise.
* Quality Notification Created Automatically (C): Notifications require manual creation or specific Customizing (e.g., defect recording), not automatic generation here.
* Missing Certificate Escalated (D): Escalation is not a standard SAP term or process in this context; it implies custom workflow not present in standard QM.
Thus, "The goods receipt is posted to blocked stock" is the correct answer.References: SAP Help Portal -

When creating an operation in an inspection plan (transaction QP01/QP02), certain fields aremandatory to define the operation's purpose and execution in SAP S/4HANA QM:
* Control Key (B): The control key is a mandatory field in the inspection plan operation. It determines the operation's behavior, such as whether inspection characteristics are required, whether it's a milestone, or if it triggers specific actions (e.g., QM01 for quality inspection). Defined in Customizing (SPRO > Quality Management > Quality Planning > Inspection Planning > Define Control Keys), it ensures the system knows how to process the operation. Without it, the operation cannot be saved.
* Activity Type (A): This is relevant for cost accounting (e.g., in Production Planning or QM orders) but is not mandatory in the inspection plan operation itself.
* Work Center (C): The work center (e.g., a test station) is optional in QM inspection plans unless specified by the control key. It's common but not universally required.
* Standard Text Key (D): This provides predefined descriptions for operations but is optional and not required to create an operation.
Thus, "Control key" is the correct answer, as it's the only mandatory assignment in standard SAP QM for inspection plan operations.References: SAP Help Portal - "Inspection Planning with Task Lists"; SAP S
/4HANA QM User Guide - "Operations in Inspection Plans".

Digital signatures in SAP S/4HANA QM (configured via SPRO > Cross-Application Components > Digital Signature) ensure auditability and compliance in critical processes:
* Recording the Usage Decision for an Inspection Lot (B): The usage decision (transaction QA11) can require a digital signature to confirm stock disposition, a common regulatory requirement (e.g., in pharmaceuticals).
* Valuation of an Inspection Result (C): Valuating results (e.g., accept/reject in QE51N) can mandate a signature, especially for critical characteristics, as set in the MIC or inspection type settings.
* Manual Confirmation of a Physical Sample Drawing (D): Confirming sample drawing (transaction QPR2) can require a signature to validate the physical process, configurable in sample management.
* Assignment of Inspection Specification (A): Assigning specs (e.g., in QP01) is a planning step, not typically requiring a signature.
* Defect Recording in Inspection Lot (E): Defect entry (e.g., QF01) may trigger notifications but doesn' t standardly require a signature unless custom-configured.
Thus, "B, C, D" are the correct answers.References: SAP Help Portal - "Digital Signatures in QM"; SAP S
