• What is the cause and solution for SAP error message WA601 - Number for number range object & could not be generated ?

  The SAP error message:
  WA601 Number for number range object & could not be generated
  typically occurs when the system tries to generate a number from a number range object but fails to do so.
  
  Cause
  
  The number range object (e.g., for documents, material numbers, purchase orders, etc.) has exhausted all available numbers in the assigned number range interval.
  The number range interval is not properly maintained or not assigned to the relevant object.
  The number range interval is not active or has incorrect settings (e.g., the interval is set with a maximum number that has already been reached).
  The number range object is not defined or missing in the system.
  The number range is external but the number was not provided manually.
  There might be authorization issues preventing number generation.
  
  
  Solution
  
  
  Check Number Range Intervals:
  
  Go to transaction SNRO (Number Range Objects) or SNUM.
  Enter the number range object mentioned in the error message.
  Check the intervals assigned to this object.
  Verify if the current number is less than the maximum number in the interval.
  If the interval is exhausted, create a new interval or extend the existing interval.
  
  
  
  Assign Number Range Interval:
  
  Ensure the number range interval is assigned to the relevant application or document type.
  For example, in MM, check the number range assignment for purchase orders or material master.
  
  
  
  Activate Number Range Interval:
  
  Make sure the interval is active and valid for the current date.
  
  
  
  Check Number Range Object Definition:
  
  Verify that the number range object exists and is correctly defined.
  
  
  
  Manual Number Assignment (if external):
  
  If the number range is external, ensure that the number is entered manually during document creation.
  
  
  
  Authorization:
  
  Check if the user has the necessary authorization to generate numbers for the object.
  
  
  
  Transport and System Consistency:
  
  Sometimes, number range intervals are transported between systems. Ensure that the intervals are consistent across development, quality, and production systems.

  Example
  If the error occurs while creating a purchase order, check the number range object EBELN:
  
  Run SNRO, enter EBELN.
  Check intervals and current number.
  If the current number equals the upper limit, create a new interval with a higher range.
  Assign the new interval to the purchasing document type.
