• What is the cause and solution for SAP error message L0018 - Maintain number range interval "&" for storage units ?

  The SAP error message L0018, which states "Maintain number range interval '&' for storage units," typically occurs when the system is unable to find a valid number range for the storage unit (SU) that you are trying to create or manage. This can happen in various scenarios, such as during the creation of storage units in warehouse management or when performing inventory management tasks.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Missing Number Range Configuration: The number range for storage units has not been defined in the system.
  Incorrect Number Range Assignment: The number range assigned to the storage unit type is either not defined or is not active.
  Number Range Interval Issues: The number range interval may be exhausted, meaning that all available numbers in the range have been used up.
  
  Solution:
  To resolve the L0018 error, you can follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Look for the number range object related to storage units, typically SNUM or similar.
  Verify if the number range intervals are defined and active.
  
  
  
  Maintain Number Range Intervals:
  
  If the number range is missing or not defined, you will need to create or adjust the number range intervals.
  Use transaction code SNRO to create or modify the number range intervals for the relevant object.
  Ensure that the intervals are set correctly and that they are not exhausted.
  
  
  
  Check Number Range Assignment:
  
  Go to the configuration settings for Warehouse Management (WM) or Inventory Management (IM).
  Ensure that the storage unit type is correctly assigned to the appropriate number range.
