• What is the cause and solution for SAP error message VN302 - Number range interval 01 has not been assigned an internal number ?

  SAP Error Message:
  
  VN302 - Number range interval 01 has not been assigned an internal number
  
  Cause:
  This error occurs when the system tries to assign a number from a number range interval (in this case, interval "01") but finds that no internal number has been assigned or the number range interval is not properly maintained or assigned. Essentially, the number range interval exists but does not have a current number or the number range object is not correctly configured.
  In SAP, number ranges are used to assign unique document numbers or identifiers automatically. If the number range interval is not properly set up or the internal number (current number) is missing, the system cannot generate the next number, leading to this error.
  
  When does it occur?
  
  During document creation or posting in modules like MM (Purchasing), FI (Financial Accounting), or SD (Sales and Distribution) where number ranges are used.
  Specifically, in the context of vendor master data or purchasing documents, since the message code is VN302 (VN typically relates to Vendor or Purchasing).
  When the system tries to fetch the next number from the number range interval "01" but fails.
  
  
  Solution:
  
  
  Check Number Range Interval Configuration:
  
  Go to transaction SNRO (Number Range Objects) or SNUM.
  Enter the relevant number range object (e.g., LIFNR for vendor numbers, or the specific object related to the process).
  Check the number range intervals defined for this object.
  Verify that interval "01" exists and has a valid From Number, To Number, and Current Number assigned.
  
  
  
  Assign Internal Number:
  
  If the current number is missing or zero, assign a valid internal number within the interval range.
  Make sure the current number is between the From and To numbers.
  
  
  
  Maintain Number Range Intervals:
  
  Use transaction SNRO or the relevant customizing path:
  
  For vendor master: SPRO ? SAP Reference IMG ? Logistics - General ? Business Partner ? Vendors ? Control ? Number Ranges ? Define Number Ranges for Vendors.
  For purchasing documents: SPRO ? Materials Management ? Purchasing ? Number Ranges.
  
  
  Ensure the number range interval "01" is assigned and active.
  
  
  
  Check Authorization:
  
  Ensure the user has authorization to access and update number ranges.
  
  
  
  If Number Range Object is Missing:
  
  Create the number range object and intervals as per business requirements.
  
  
  
  
  Additional Information:
  
  Number ranges are critical for document numbering and must be carefully maintained.
  Number range intervals can be internal (system assigns numbers automatically) or external (user enters numbers manually).
  The error message VN302 is specific to number range assignment issues.
  Always back up current number range settings before making changes.
  If the problem persists after checking number ranges, check for any custom enhancements or user exits that might interfere with number assignment.
