This error indicates that there is an attempt to allocate the same order number to multiple transactions, which is not allowed in the system.
  Cause:
  
  
  Duplicate Order Allocation: The most common cause of this error is that the same order number is being processed or allocated multiple times. This can happen due to:
  
  Manual entry errors where the same order is selected more than once.
  System issues or bugs that cause the same order to be processed in parallel.
  Incorrect configuration or settings in the order management module.
  
  
  
  Concurrency Issues: If multiple users or processes are trying to allocate the same order simultaneously, it can lead to this error.
  
  
  Data Integrity Issues: There may be inconsistencies in the database or issues with the data being processed, leading to duplicate entries.
  
  
  Solution:
  
  
  Check for Duplicates: Review the order numbers being processed to ensure that there are no duplicates. This can be done by checking the transaction logs or the relevant tables in SAP.
  
  
  Review User Actions: If multiple users are involved, ensure that they are not trying to allocate the same order at the same time. Implementing proper user training and guidelines can help mitigate this issue.
  
  
  System Configuration: Check the configuration settings in the order management module to ensure that they are set up correctly to prevent duplicate allocations.
  
  
  Error Handling: Implement error handling in your processes to catch and manage this error gracefully. This may involve adding checks before allocation to ensure that the order number has not already been allocated.
