• What is the cause and solution for SAP error message WS402 - Number range object &1 is not maintained ?

  SAP Error Message:
  
  WS402 - Number range object &1 is not maintained
  
  Cause:
  This error occurs when the system tries to assign a number from a number range object that has not been maintained or defined in the system. Number range objects are used in SAP to generate unique numbers for various business documents or master data (e.g., material numbers, purchase order numbers, invoice numbers).
  If the number range object specified in the transaction or program does not have any intervals defined or is missing entirely, the system cannot generate a number, resulting in this error.
  
  Explanation:
  
  The placeholder &1 in the message will be replaced by the actual number range object name that is missing or not maintained.
  Number range objects are maintained in transaction SNRO or SNUM.
  This error typically happens during document creation or master data creation when the system tries to fetch the next number from the number range object.
  
  
  Solution:
  
  
  Identify the Number Range Object:
  
  From the error message, note the number range object name (e.g., MATERIALNR, EBELN, etc.).
  
  
  
  Maintain Number Range Intervals:
  
  Go to transaction SNRO (Number Range Objects).
  Enter the number range object name from the error message.
  Click on Intervals.
  Check if any intervals are defined for the relevant application area or client.
  If no intervals exist, create a new interval by specifying:
  
  Interval name
  From number
  To number
  Current number (usually set to the start number minus one)
  
  
  Save your entries.
  
  
  
  Check Authorization:
  
  Ensure you have the necessary authorization to maintain number ranges.
  
  
  
  Test the Transaction Again:
  
  After maintaining the number range, retry the transaction or process that caused the error.
  
  
  
  
  Additional Information:
  
  Transaction SNRO: Used to maintain number range objects and intervals.
  Transaction SNUM: Also used for number range maintenance in some SAP systems.
  Number ranges can be internal (system assigns numbers automatically) or external (user enters numbers manually).
  Always ensure number ranges do not overlap and have sufficient capacity to avoid running out of numbers.
  Some number ranges are client-specific; ensure you maintain intervals for the correct client.
  
  
  Example:
  If the error message is:
  
  WS402 Number range object MATERIALNR is not maintained
  Steps:  
  
  Go to SNRO  
  Enter MATERIALNR  
  Click Intervals  
  If empty, create a new interval, e.g., from 100000 to 199999  
  Save and exit  
  Retry material creation
  
  
  If you need further help, please provide the number range object name or the transaction where the error occurs.
