• What is the cause and solution for SAP error message /SCWM/WHO131 - Maximum number of WTs per order reached ?

  The SAP error message /SCWM/WHO131 Maximum number of WTs per order reached typically occurs in the SAP Extended Warehouse Management (EWM) module when the system has reached the maximum limit of Warehouse Tasks (WTs) that can be created for a single order. This limit is set to prevent performance issues and to manage the workload effectively.
  Cause:
  
  Exceeding WT Limit: Each order in SAP EWM has a predefined limit for the number of Warehouse Tasks that can be associated with it. When this limit is exceeded, the system generates the error message.
  Configuration Settings: The maximum number of WTs per order is defined in the system configuration. If the limit is set too low for the volume of transactions being processed, this error can occur.
  Order Complexity: Orders that involve multiple items or require complex handling may generate a high number of WTs, leading to this error.
  
  Solution:
  
  
  Increase the WT Limit:
  
  You can increase the maximum number of WTs allowed per order in the configuration settings. This is typically done in the Customizing settings of SAP EWM.
  Navigate to the following path in the SAP GUI: 
  SPRO -> Logistics Execution -> Extended Warehouse Management -> Warehouse Management -> Define Maximum Number of Warehouse Tasks per Order
  
  Adjust the limit according to your business needs and the expected volume of WTs.
  
  
  
  Optimize Order Processing:
  
  Review the order processing strategy to see if it can be optimized to reduce the number of WTs generated per order. This may involve consolidating items or changing how tasks are created.
  
  
  
  Batch Processing:
  
  If applicable, consider processing orders in batches to avoid hitting the WT limit for individual orders.
  
  
  
  Monitor and Analyze:
  
  Monitor the number of WTs being generated for orders and analyze patterns to understand when and why the limit is being reached. This can help in making informed decisions about configuration changes.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
  Performance Considerations: Be aware that increasing the WT limit may have performance implications. Ensure that your system can handle the increased load.
  Testing: After making configuration changes, conduct thorough testing to ensure that the changes resolve the issue without introducing new problems.
  
  By addressing the configuration settings and optimizing order processing, you should be able to resolve the /SCWM/WHO131 error and improve the efficiency of your warehouse operations.
