• What is the cause and solution for SAP error message IW402 - System: No external number range ?

  The SAP error message IW402 ("System: No external number range") typically occurs when you are trying to create or process a maintenance order or a similar object that requires a number assignment, but the system is unable to find an external number range defined for that object. This can happen in various modules, including Plant Maintenance (PM) or other areas where number ranges are utilized.
  Cause:
  
  Missing Number Range Configuration: The external number range for the specific object type (e.g., maintenance order) has not been defined in the system.
  Incorrect Number Range Assignment: The number range may be incorrectly assigned or configured in the system settings.
  Authorization Issues: The user may not have the necessary authorizations to access or use the defined number ranges.
  System Settings: The system may be set to use internal number ranges, but the transaction is trying to use an external number range.
  
  Solution:
  To resolve the IW402 error, you can follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object (e.g., for maintenance orders, it might be PM_ORDER).
  Check if there is an external number range defined. If not, you will need to create one.
  
  
  
  Create or Adjust Number Range:
  
  If the external number range does not exist, you can create it by:
  
  Selecting the number range object.
  Clicking on "Intervals" and defining a new interval for the external number range.
  
  
  Ensure that the number range is set to "External" and that the intervals are correctly defined.
  
  
  
  Check User Authorizations:
  
  Ensure that the user has the necessary authorizations to access the number range. This can be checked in the user roles and profiles.
  
  
  
  Review Configuration Settings:
  
  Check the configuration settings in the relevant module (e.g., PM) to ensure that the system is set to use external number ranges where required.
  
  
  
  Testing:
  
  After making the necessary changes, test the transaction again to see if the error persists.
