  Cause:
  The error occurs when:
  
  A shifting order (which is a type of data transformation or mapping) has been defined for a specific target interval, and there is an attempt to create or modify another shifting order for the same interval.
  This can happen if there are overlapping or conflicting configurations in the data migration setup, leading to the system preventing the creation of duplicate or conflicting entries.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Shifting Orders:

  Modify or Delete Conflicting Orders:
  
  If you find that there is indeed a conflicting shifting order, you may need to either modify it to accommodate your new requirements or delete it if it is no longer needed.

  Consult Documentation:
  
  Refer to the SAP documentation or notes related to the specific data migration tool you are using. There may be specific guidelines or best practices for managing shifting orders.
  
  
  
  Check for Custom Logic:
  
  If there is custom logic or enhancements in your SAP environment, ensure that they are not causing conflicts with the standard behavior of shifting orders.
  
  
  
  Testing:
  
  After making changes, conduct thorough testing to ensure that the data migration process works as expected without triggering the error again.
