This error indicates that there is an attempt to create or modify an entry with a start date that already exists in the system for the same object or record.
  Cause:
  
  Duplicate Start Date: The primary cause of this error is that the start date you are trying to enter already exists for another record in the same context (e.g., for the same material, customer, or other relevant object).
  Data Entry Error: It may also occur due to a simple data entry mistake where the user inadvertently tries to enter a date that is already in use.
  Configuration Issues: In some cases, the configuration of the system may not allow overlapping date ranges for certain records.
  
  Solution:
  
  Check Existing Records: Review the existing records to see if there is already an entry with the same start date. You can do this by querying the relevant table or using transaction codes that allow you to view the data.
  Modify the Date: If you find that the start date is indeed already in use, you will need to either:
  
  Change the start date to a different value that does not conflict with existing records.
  If applicable, adjust the existing record to allow for the new entry (e.g., changing the end date of the existing record).
  
  
  Consult Documentation: If you are unsure about the rules governing date entries for the specific object you are working with, consult the SAP documentation or your organization's guidelines.
  Check Configuration: If you believe the error is due to a configuration issue, consult with your SAP Basis or configuration team to review the settings related to date management for the relevant module.
