This error indicates that there is an attempt to create or modify a record with a "Date To" value that already exists for another record, leading to a conflict.
  Cause:

  Solution:
  
  Check Existing Records: Review the existing records in the relevant table or transaction to identify if there is already a record with the same "Date To" value. You can use transaction codes like SE16 or SE11 to view the underlying database tables.
  Modify the Date: If you find a conflict, you can either change the "Date To" value of the new record you are trying to create or modify the existing record to ensure that both do not have the same "Date To."
  Data Cleanup: If this error arises from data migration, ensure that the data being imported is cleaned up to avoid duplicates in date ranges.
  Consult Documentation: Refer to SAP documentation or help files for specific guidelines on managing date ranges in the context of the module you are working with (e.g., Master Data, Sales and Distribution, etc.).
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes that may help in troubleshooting, such as SE16 (Data Browser), SE11 (Data Dictionary), or specific transaction codes related to the module you are working with.
