  The SAP error message /SCWM/L3028 Automatic HU WT creation started for tRFC queue &1 typically relates to the handling of Handling Units (HUs) in the Extended Warehouse Management (EWM) module. This message indicates that the system has initiated the automatic creation of Warehouse Tasks (WTs) for Handling Units (HUs) using the transactional Remote Function Call (tRFC) mechanism.
  Cause:
  
  tRFC Queue Issues: The error may arise if there are issues with the tRFC queue, such as it being stuck or having entries that cannot be processed.
  Configuration Issues: There may be configuration issues in the EWM system that prevent the automatic creation of WTs.
  Data Issues: Inconsistent or missing data related to the Handling Units or Warehouse Tasks can also lead to this error.
  System Performance: High system load or performance issues can cause delays or failures in processing the tRFC calls.
  
  Solution:
  
  
  Check tRFC Queue: 
  
  Use transaction SM58 to monitor the tRFC queue. Look for any entries that are stuck or have errors. If you find any, you may need to analyze and resolve the underlying issues.
  You can also use transaction SMQ1 (for outbound queues) and SMQ2 (for inbound queues) to check the status of the queues.
  
  
  
  Review Configuration:
  
  Ensure that the configuration for Handling Units and Warehouse Tasks in EWM is correctly set up. This includes checking the settings for automatic WT creation.

  Look for any inconsistencies in the data that might prevent the creation of WTs.
  
  
  
  System Performance:
  
  Monitor system performance and check for any bottlenecks that might be affecting the processing of tRFC calls.
  If necessary, consider optimizing system resources or scheduling batch jobs during off-peak hours.
  
  
  
  Logs and Traces:
  
  Review application logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the issue.
  Enable traces if needed to gather more detailed information about the processing of the tRFC calls.
