• What is the cause and solution for SAP error message NJIT_O_MSG091 - Same JIT header reference type is specified more than once ?

  The SAP error message NJIT_O_MSG091 indicates that there is a problem with the configuration of Just-In-Time (JIT) delivery in the system. Specifically, it means that the same JIT header reference type has been specified more than once in the configuration or in the data being processed. This can lead to confusion in the system as it expects unique reference types for JIT deliveries.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are duplicate entries for the same JIT header reference type in the configuration or in the data being processed.
  Incorrect Configuration: The JIT configuration may not be set up correctly, leading to multiple references being defined for the same type.
  Data Issues: The data being processed may contain errors or duplicates that violate the uniqueness requirement for JIT header reference types.
  
  Solution:
  
  
  Check Configuration:
  
  Go to the JIT configuration settings in your SAP system.
  Verify that each JIT header reference type is defined only once. Remove any duplicates that you find.
  
  
  
  Review Data:
  
  Check the data being processed for JIT deliveries. Look for any duplicate entries that may be causing the issue.
  If you find duplicates, correct the data to ensure that each JIT header reference type is unique.
  
  
  
  Testing:
  
  After making the necessary changes, test the JIT process again to ensure that the error does not occur.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed guidance on JIT configuration and troubleshooting.
