In SAP S/4HANA QM, an inspection plan group contains multiple inspection plans, each identified by a unique group counter. When an inspection lot is created (e.g., for goods receipt or production), the system must select the appropriate plan from the group:
* Lot Size (D): The lot size of the inspection lot is the primary determinant for selecting an inspection plan. In the inspection plan header (transaction QP01/QP02), you define a "usage" and "lot size range" for each plan within the group. The system matches the inspection lot's size to the applicable lot size range in the plan, ensuring the correct plan is chosen. This is standard behavior in QM (e.g., for inspection lot origin 01 or 03).
* Sample Size (A): Sample size is determined by the sampling procedure within the inspection plan, not the other way around. It doesn't select the plan.
* Material Type (B): Material type influences material master settings but does not directlydetermine the inspection plan selection within a group.
* Procurement Type of the Material (C): Procurement type (e.g., in-house vs. external) might influence the inspection type, but it doesn't select between plans in a group.
Thus, "Lot size" is the correct answer, as it aligns with SAP's logic for task list selection.References: SAP Help Portal - "Inspection Planning with Task Lists"; SAP S/4HANA QM User Guide - "Inspection Lot Creation".
