• What is the cause and solution for SAP error message VHU01066 - The system could not assign new internal item numbers ?

  SAP Error Message:
  
  VHU01066 – The system could not assign new internal item numbers
  
  Cause:
  This error typically occurs in the Vehicle Management System (VMS) or related SAP modules when the system tries to assign internal item numbers (e.g., for vehicle items, equipment, or components) but fails because the number range for these internal item numbers is either:
  
  Exhausted (no more numbers available in the assigned number range), or  
  Not properly configured or assigned to the relevant object or transaction.
  
  In other words, the system attempts to generate a new internal item number but cannot find a free number in the configured number range interval.
  
  Solution:
  
  
  Check Number Range Intervals:
  
  Go to transaction SNRO or SNUM (depending on SAP version) to check the number range object related to internal item numbers (e.g., VHU_ITEMNR or similar).
  Verify if the current number range interval is exhausted (i.e., the current number has reached the upper limit).
  
  
  
  Extend Number Range:
  
  If the number range is exhausted, create a new number range interval with a higher range.
  Assign this new interval to the relevant number range object.
  
  
  
  Assign Number Range to Object:
  
  Ensure that the number range object is correctly assigned to the relevant vehicle or equipment item type or transaction.
  This can be checked in customizing under Vehicle Management or Equipment Management settings.
  
  
  
  Check Customizing Settings:
  
  Use transaction SPRO ? Logistics Execution ? Vehicle Management ? Basic Settings ? Number Ranges.
  Verify the number range intervals and assignments.
  
  
  
  Restart the Process:
  
  After extending or correcting the number range, retry the transaction or process that caused the error.
  
  
  
  
  Related Information:
  
  This error is common in Vehicle Management System (VMS) when creating or modifying vehicle items or equipment.
  Number ranges in SAP are critical for unique identification of objects; running out of numbers can halt business processes.
  Regular monitoring of number ranges is recommended to avoid such interruptions.
  If unsure about the number range object name, check the documentation or consult with your SAP VMS functional consultant.
