Which of the following sample categories can be maintained in the sample-drawing item?

Sample-drawing items in the sample-drawing procedure (transaction QPV2) define sample categories:

Reserve Sample (A): A standard category for samples retained for future testing (e.g., stability), maintained in the procedure.

Pooled Sample (B): Represents combined samples for collective testing, a defined category in sample management.

Primary Sample (D): The initial sample taken for immediate inspection, a core category in the procedure.

Initial Sample (C): Not a distinct category; overlaps with "Primary sample."

Sample for Storage Condition (E): Not a standard category; storage conditions are attributes, not sample types.

Thus, "Reserve sample," "Pooled sample," and "Primary sample" are the correct answers.References: SAP Help Portal - "Sample Management in QM"; SAP S/4HANA QM User Guide - "Sample-Drawing Procedure".
