Sample Management: Physical Samples, Drawing and Traceability

Key takeaway

Use sample management to define, create and track physical samples that represent inspection material while preserving identity, quantity and relationship to the inspection lot.

Explanation

📌 KEY POINTS
✅ Sample management is for explicit PHYSICAL samples, not just an abstract sample size number.
⚠️ Don't create sample records without a clear testing or retention purpose.
💡 Regulatory labs often need proof the tested sample IS the sample drawn from the production/receipt lot — chain of custody matters.

━━━━━━━━━━━━━━━━━━━━
▶ 1. WHAT A SAMPLE REPRESENTS

Material drawn from a batch, container, process, or inspection lot for laboratory or controlled testing

━━━━━━━━━━━━━━━━━━━━
▶ 2. THE MECHANISM

Sampling procedure + sample-drawing instructions determine how much material is taken and how samples are organized
Physical sample records preserve identification and status so lab results trace back to the originating lot/material

━━━━━━━━━━━━━━━━━━━━
▶ 3. WHAT THE PROCESS MUST ADDRESS

Sample quantity, storage, retention, destruction, chain of custody where required

━━━━━━━━━━━━━━━━━━━━
⚠️ 4. THE DISCIPLINE

Don't create sample records without a clear testing or retention purpose — excessive complexity adds administration without improving control
For LIMS integration, use stable sample and inspection identifiers so results return to the correct lot and characteristic

━━━━━━━━━━━━━━━━━━━━
▶ 5. ACROSS RELEASES

LIMS integration works on both ECC and S/4HANA; S/4HANA additionally exposes sample drawing/tracking through Fiori apps

✅ CHECKPOINT: explain why "chain of custody" matters for a regulatory lab result.

Real project scenario

A regulated batch required a retained reference sample for two years. The company originally tracked samples in spreadsheets. Using physical sample records connected retention status directly to the inspection lot and batch.

Common mistakes

Treating sample quantity as the same thing as a physical sample record.
Losing sample-to-batch identity.
Having no retention/disposal rule.
Creating unnecessary sample hierarchies.
Integrating lab results without stable sample IDs.

Best practices

Define sample purpose and lifecycle.
Preserve lot and batch traceability.
Govern retention and disposal.
Use stable identifiers for labs.
Keep sample structures as simple as possible.

Interview angle

Explain why physical sample management is needed beyond ordinary sampling procedure.

Quick check

1. In the lesson "Sample Management: Physical Samples, Drawing and Traceability", consider this project situation: A regulated batch required a retained reference sample for two years. Which statement is correct?

2. During a physical sample drawing process for incoming inspection, samples are not appearing correctly linked to their storage location, and lab technicians cannot trace which physical sample corresponds to which inspection lot. How would you troubleshoot and correct this? Choose the response that best aligns with the expected SAP approach.

3. A pharmaceutical manufacturer needs to run long-term stability studies on a product to determine shelf life, with samples pulled at defined intervals over multiple years, and results must feed into the master certificate and expiration date logic. What are the key design considerations? Choose the response that best aligns with the expected SAP approach.
