• What is the cause and solution for SAP error message L2603 - Number assignment not executed. TRs not created ?

  The SAP error message L2603 ("Number assignment not executed. TRs not created") typically occurs in the context of number range management, particularly when dealing with transaction records (TRs) in the Logistics module. This error indicates that the system was unable to assign a number to a transaction, which is necessary for creating transport requests (TRs) in the system.
  Causes:
  
  
  Number Range Issues: The number range for the specific document type may not be defined or may be exhausted. This can happen if the number range is not properly configured or if all available numbers have been used.
  
  
  Authorization Issues: The user may not have the necessary authorizations to create or manage transport requests.
  
  
  Configuration Errors: There may be configuration issues in the system related to the transport management system (TMS) or the specific module you are working with.
  
  
  System Lock: The system might be locked for some reason, preventing the creation of new transport requests.
  
  
  Transport Directory Issues: Problems with the transport directory or transport routes can also lead to this error.
  
  
  Solutions:
  
  
  Check Number Ranges:
  
  Go to transaction code SNRO (Number Range Objects) and check the number range object related to the document type you are working with.
  Ensure that the number range is defined and that there are available numbers. If necessary, extend the number range.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary authorizations to create transport requests. This can be checked in transaction SU53 or by reviewing the user's roles and authorizations.
  
  
  
  Configuration Review:
  
  Check the configuration settings for the transport management system (TMS) using transaction STMS. Ensure that the transport routes and layers are correctly set up.
  
  
  
  System Lock Check:
  
  Check if there are any system locks that might be preventing the creation of transport requests. You can use transaction SM12 to view and manage locks.
  
  
  
  Transport Directory:
