• What is the cause and solution for SAP error message /SCWM/GM021 - Maximum number of storage units exceeded in storage bin &1 ?

  The SAP error message /SCWM/GM021 Maximum number of storage units exceeded in storage bin &1 typically occurs in the SAP Extended Warehouse Management (EWM) module. This error indicates that the number of storage units (SUs) in a specific storage bin has exceeded the maximum limit defined for that bin.
  Cause:
  
  Configuration Limits: Each storage bin in SAP EWM can have a maximum number of storage units defined in its configuration. If you attempt to place more storage units in that bin than allowed, this error will be triggered.
  Incorrect Warehouse Management Settings: The settings for the storage bin may not be configured correctly, leading to an unexpected limit being reached.
  High Volume of Goods Movement: If there is a sudden influx of goods or a bulk transfer of storage units into the bin, it may exceed the configured limit.
  
  Solution:
  
  
  Check Storage Bin Configuration:
  
  Go to the storage bin configuration in the SAP EWM system.
  Verify the maximum number of storage units allowed for the specific storage bin. This can be done in the transaction code /SCWM/BS (Bin Master Data).
  If necessary, increase the maximum limit for that storage bin to accommodate more storage units.
  
  
  
  Redistribute Storage Units:
  
  If increasing the limit is not feasible, consider redistributing the storage units to other bins that have available capacity.
  Use the warehouse management processes to move excess storage units to different bins.
  
  
  
  Review Goods Movement Processes:
  
  Analyze the goods movement processes to ensure that they are being executed correctly and that they are not causing unnecessary congestion in specific storage bins.
  
  
  
  Monitor Warehouse Operations:
  
  Implement monitoring tools or reports to keep track of storage unit levels in bins to prevent future occurrences of this error.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SCWM/BS for bin management and /SCWM/GR for goods receipt processes.
  Warehouse Management Best Practices: Review best practices for warehouse management to optimize storage unit allocation and prevent overloading specific bins.
  SAP Notes: Check for any SAP Notes related to this error message for additional insights or patches that may address underlying issues.
  
  By addressing the configuration and operational aspects of your warehouse management, you can resolve the error and prevent it from occurring in the future.
