• What is the cause and solution for SAP error message >A406 - The number range interval for the objects &1 and &2 overlap. ?

  The SAP error message A406 indicates that there is an overlap in the number range intervals for two different objects. This typically occurs when two different number ranges are configured to use the same range of numbers, which can lead to conflicts when the system tries to assign a new number.
  Cause:
  The error is caused by the configuration of number ranges in the SAP system. Specifically, it occurs when:
  
  Two different objects (e.g., document types, transaction types) are assigned number ranges that overlap.
  The number range intervals for these objects are not properly defined, leading to a situation where the same number could be assigned to both objects.
  
  Solution:
  To resolve this error, you need to check and adjust the number range intervals for the affected objects. Here are the steps to do this:
  
  
  Identify the Objects: The error message will indicate which two objects are causing the conflict (represented by &1 and &2). Note these objects for further investigation.
  
  
  Access Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Enter the name of the number range object related to the first object (e.g., document type) and click on "Intervals".
  
  
  
  Check Intervals: Review the defined intervals for both objects. Look for any overlapping ranges.
  
  
  Adjust Intervals:
  
  If you find overlapping intervals, you will need to adjust one or both of the intervals to ensure they do not overlap.
  You can either change the start and end values of the intervals or create new intervals that do not conflict.
  
  
  
  Save Changes: After making the necessary adjustments, save your changes.
  
  
  Test the Changes: After adjusting the number ranges, test the functionality that was causing the error to ensure that the issue has been resolved.
  
  
  Related Information:
  
  
  Transaction Codes: 
  
  SNRO: To manage number range objects.
  SNUM: To display and manage number ranges.
  
  
  
  Documentation: Refer to SAP Help documentation for detailed information on number range management and best practices.
  
  
  Transport Requests: If you are working in a development environment, ensure that any changes made to number ranges are transported to the quality and production environments as needed.
  
  
  Consulting Basis Team: If you are unsure about making changes to number ranges, it may be beneficial to consult with your SAP Basis or configuration team to avoid unintended consequences.
  
  
  By following these steps, you should be able to resolve the A406 error and prevent it from occurring in the future.
