Qualitative inspection characteristics are evaluated based on attributes (e.g., pass/fail, presence of a defect) rather than numerical measurements.

Attributive inspection nonconforming units: This valuation mode is specifically designed for qualitative characteristics. The system evaluates the results based on the number of nonconforming units or defect codes recorded, automatically proposing an acceptance or rejection.

Manual valuation: This mode requires the inspector to manually set the valuation to "accepted" or "rejected." It is a valid option for any characteristic type, including qualitative ones where subjective judgment (like a visual check) is necessary and cannot be fully automated.

B. Variable inspection s-method: This is used for quantitative (variable) characteristics. It valuates the inspection results based on the calculated standard deviation ('s') of the measured values, which is not applicable to qualitative data.

D. Mean value within tolerance range: This is also used for quantitative characteristics. The system calculates the mean of several measured values and checks if it falls within the defined tolerance limits, a concept irrelevant to attributive data.

1. SAP S/4HANA Help Portal: Control Indicators for Master Inspection Characteristics. In the section detailing the control indicators for a master inspection characteristic (MIC)

the "Valuation mode" field is described. The documentation specifies that modes like "Valuation based on the number of nonconforming units" are for attributive inspections (qualitative)

while modes like "Mean value within the tolerance range" and "s-method" are for variable inspections (quantitative). Manual valuation is listed as a universally applicable option.

2. SAP Training Manual S4525 (SAP S/4HANA Quality Management - Quality Planning and Inspection): Unit 3

Lesson: Master Inspection Characteristics. This lesson explains the creation and configuration of MICs. It explicitly differentiates the control indicators and valuation modes applicable to qualitative versus quantitative characteristics

aligning with the explanation above. Attributive and manual valuations are shown as valid for qualitative MICs.
