In an SAP S/4HANA Embedded EWM system, we are facing an issue where negative stock is appearing in certain storage bins.

Issue Description:

  • Stock quantity shows negative value in /SCWM/MON

  • No physical negative stock in warehouse

  • ERP stock appears correct

  • No obvious error during goods movement

  • Issue occurs after picking or posting change

System Behavior:

  • Warehouse Task confirmation completed

  • Delivery appears processed

  • No open WTs

  • No short dump

  • No visible queue failure

Business Impact:

  • Inventory inconsistency

  • Audit risk

  • Picking errors

  • Replenishment planning incorrect

Checks Already Performed:

  • SMQ1 / SMQ2 checked

  • Stock overview verified

  • Delivery document reviewed

  • No visible system error

Despite this, negative stock still exists in EWM.

My Questions:

  1. What are the most common reasons for negative stock in SAP EWM?

  2. How can we identify which process created the inconsistency?

  3. Which tables or monitors should be checked first?

  4. How to safely correct negative stock in production?

  5. How to prevent negative stock issues in future?

Looking for practical troubleshooting guidance based on real project experience.
