In pharmaceutical and regulated industries, controlling remaining shelf life during WT creation is critical for compliance. While FEFO and sort rules help, they are not sufficient to fully enforce minimum SLED validation.

A robust design requires a combination of:

• Standard configuration

• Batch determination strategy

• Stock removal control

• Enhancement (if strict blocking is required)

Below is the recommended real-project approach.

🔹 1️⃣ Understand Standard System Behavior First

Standard SAP EWM supports:

✔ FEFO (First Expired First Out)
✔ Batch determination
✔ Shelf life relevance in product master
✔ Sort rules based on SLED

However:

❌ Standard FEFO does not block WT creation if minimum remaining shelf life is not met.
❌ It only sorts stock — it does not enforce business rule validation.

That is why configuration alone is often insufficient.

🔹 2️⃣ Outbound Picking – Best Practice Design

✔ Step 1: Maintain SLED & Minimum Remaining Shelf Life

In product master:

• Maintain shelf life expiration data

• Maintain minimum remaining shelf life

Ensure batch classification is correct.

✔ Step 2: Use FEFO + Sort Rule (First Level Control)

Configure:

• Stock removal strategy = FEFO

• Sort rule based on expiration date

• Batch determination active

This ensures:
👉 System proposes oldest valid stock first.

But this alone does not enforce 90-day rule strictly.

✔ Step 3: Enforce Hard Stop Using BAdI (Recommended for Pharma)

If business requires:

“Do not create WT if remaining SLED < 90 days”

Then enhancement is required.

Commonly Used BAdI in Real Projects:

or

These BAdIs allow you to:

• Validate remaining shelf life dynamically

• Compare SLED against current date

• Throw error message

• Prevent WT creation

This is the most reliable approach in regulated environments.

🔹 3️⃣ Inbound Putaway – Directing Short SLED to Fast-Pick Areas

For inbound control:

✔ Option 1: Storage Type Search Sequence

Define:

• Storage type determination based on:

  • Shelf life remaining

  • Stock type

  • Putaway control indicator

But this requires enhancement if dynamic logic is complex.

✔ Option 2 (More Flexible): BAdI for Storage Type Determination

Common BAdI used:

This allows:

• Reading SLED at GR

• Determining remaining days

• Assigning storage type dynamically

  • Short SLED → Fast picking area

  • Long SLED → Bulk storage

This is widely used in pharma implementations.

🔹 4️⃣ Recommended Overall Architecture

For strict pharma compliance:

✔ Configuration Layer

• FEFO strategy

• Sort rule

• Batch determination

• Minimum remaining shelf life in material master

✔ Validation Layer (Enhancement)

• BAdI to enforce minimum remaining SLED

• Hard error if criteria not met

✔ Putaway Optimization Layer

• Dynamic storage type determination via BAdI

This ensures:

• Compliance

• Audit readiness

• Controlled WT creation

🔹 5️⃣ Common Design Mistakes

❌ Relying only on FEFO
❌ Not validating remaining days dynamically
❌ Ignoring time zone/date calculation
❌ Allowing manual override without audit log
❌ Not testing edge cases (partial batch, mixed HU)

🔹 6️⃣ Real Project Recommendation

In pharmaceutical projects:

✔ Always implement enhancement for SLED validation
✔ Log validation messages for audit
✔ Prevent manual bypass
✔ Test year-end date transitions
✔ Document SLED logic in functional specification

Because in regulated industries:

Compliance requirement > Standard convenience.

🔑 Final Answer to Your Question

✔ Is configuration alone enough?

No — configuration handles sorting but not strict blocking.

✔ Is BAdI required?

Yes, if business requires minimum remaining shelf life enforcement.

✔ Which BAdIs are commonly used?

• /SCWM/EX_CORE_STOCK_REMOVAL

• /SCWM/EX_WHO_CREATE

• /SCWM/EX_CORE_PTS_DET (for putaway logic)
