If waves are released successfully but picking tasks are not created, the issue is usually related to wave template configuration, warehouse process type determination, or warehouse order creation rules.

Below is a structured troubleshooting approach commonly used in real SAP EWM projects.

 Check Wave Template Configuration

Wave templates control how warehouse tasks are created when a wave is released.

Check configuration:

SPRO → Extended Warehouse Management → Goods Issue Process → Wave Management → Define Wave Templates

Verify:

• Wave template assigned to delivery type

• Warehouse task creation indicator active

• Correct warehouse process type determination

If the wave template does not trigger task creation, picking tasks will not be generated.

 Verify Warehouse Process Type (WPT) Determination

Warehouse tasks cannot be created if the system cannot determine the correct Warehouse Process Type.

Check configuration:

SPRO → Extended Warehouse Management → Cross Process Settings → Warehouse Task → Determine Warehouse Process Type

Verify:

• Correct WPT maintained for picking

• WPT linked to activity area and document type

• WPT allows picking operations

If WPT cannot be determined, warehouse tasks will not be generated.

 Check Warehouse Order Creation Rules (WOCR)

Even if warehouse tasks are created, they may not be grouped correctly if WOCR configuration is missing.

Check configuration:

SPRO → Extended Warehouse Management → Cross Process Settings → Warehouse Order → Define Warehouse Order Creation Rules

Verify:

• WOCR assigned to picking process

• Warehouse task grouping rules maintained

• Limits for warehouse orders configured correctly

Incorrect WOCR configuration may prevent task creation during wave release.

 Verify Activity Area and Storage Type Settings

Wave-based picking relies on proper activity area and storage type configuration.

Check:

• Storage bins assigned to correct activity area

• Picking storage type defined correctly

• Product assigned to the correct storage type

If activity areas are missing or incorrectly configured, the system may not generate picking tasks.

 Check Warehouse Monitor

Use the Warehouse Monitor to review wave processing status.

Transaction:

/SCWM/MON

Navigate to:

Outbound Process → Wave Management

Verify:

• Wave release status

• Delivery assignments

• Warehouse task creation status

This monitor helps identify whether the system recognized the wave correctly.

 Check Application Logs

If configuration appears correct, check application logs for hidden errors.

Transaction:

SLG1

Suggested objects:

• /SCWM/WAVE

• /SCWM/DELIVERY

These logs may show determination errors or configuration issues.

 Verify Queue Processing

Even though queues appear successful, it is still important to confirm integration messages.

Check:

SMQ1 – Outbound queue (ERP)
SMQ2 – Inbound queue (EWM)

Queue failures during delivery processing may prevent warehouse task creation.

 Real Project Example

In one SAP S/4HANA Embedded EWM implementation, waves were released but picking tasks were not created.

Root cause:

The wave template was correctly assigned, but warehouse process type determination for picking was missing.

After configuring the correct WPT and re-releasing the wave, the system generated warehouse tasks automatically.

🛠 Recommended Troubleshooting Sequence

When picking tasks are not created after wave release:

1️⃣ Verify wave template configuration
2️⃣ Check warehouse process type determination
3️⃣ Review warehouse order creation rules (WOCR)
4️⃣ Confirm activity area and storage type configuration
5️⃣ Monitor wave processing in /SCWM/MON
6️⃣ Review application logs in SLG1
7️⃣ Check queues in SMQ1 / SMQ2

This structured approach usually identifies the issue quickly.

 Conclusion

If Wave Management does not create picking tasks in SAP EWM, the most common causes are:

• Incorrect wave template configuration

• Missing warehouse process type determination

• Incorrect warehouse order creation rules

• Activity area or storage type configuration issues

Once these configuration elements are verified and corrected, wave release should automatically generate picking warehouse tasks.
