• What is the cause and solution for SAP error message /SCWM/WHO144 - Maximum number of WTs per HU exceeded. WTs in next rule ?

  The SAP error message /SCWM/WHO144 Maximum number of WTs per HU exceeded. WTs in next rule? typically occurs in the context of SAP Extended Warehouse Management (EWM) when handling Handling Units (HUs) and Work Tasks (WTs). This error indicates that the maximum number of Work Tasks that can be assigned to a single Handling Unit has been exceeded.
  Cause:
  
  Configuration Limits: The system has a predefined limit for the number of Work Tasks that can be associated with a single Handling Unit. This limit is set in the system configuration.
  Business Process Design: The way the warehouse processes are designed may lead to situations where too many WTs are being generated for a single HU.
  Data Entry Errors: Incorrect data entry or system errors may lead to an unexpected number of WTs being created for a single HU.
  
  Solution:
  
  
  Check Configuration: Review the configuration settings in SAP EWM to determine the maximum number of WTs allowed per HU. This can typically be found in the Customizing settings under the Warehouse Management section.
  
  Navigate to: SPRO > Logistics Execution > Extended Warehouse Management > Warehouse Operations > Handling Unit Management > Define Maximum Number of Work Tasks per Handling Unit.
  Adjust the limit if necessary, but ensure that this change aligns with your business processes.
  
  
  
  Review Work Task Creation Logic: Analyze the logic that generates Work Tasks for Handling Units. Ensure that the process is designed to create an appropriate number of WTs per HU.
  
  
  Split Handling Units: If the number of WTs is inherently high due to the nature of the goods being handled, consider splitting the Handling Units into smaller units that can each accommodate the allowed number of WTs.
  
  
  Error Handling: Implement error handling in your processes to catch and manage situations where the maximum limit is approached or exceeded.
  
  
  Consult Documentation: Refer to SAP documentation or help notes related to this error for additional insights and recommendations.
