This error indicates that you are trying to set an effective date for a record that is earlier than a previously defined effective date for the same record.
  Cause:
  
  Date Overlap: You are attempting to enter a new effective date that conflicts with an existing record's effective date. For example, if you have a record with an effective date of January 1, 2023, and you try to enter a new record with an effective date of December 31, 2022, this error will occur.

  Solution:
  
  Check Existing Records: Review the existing records for the same object (e.g., project, maintenance order) to identify the effective dates that are already set. Ensure that the new effective date you are trying to enter is later than any existing effective dates.
  Adjust the Effective Date: If you find that the effective date you are trying to enter is indeed earlier than an existing date, adjust it to a date that is valid (i.e., later than the previous effective date).
  Consult Documentation: If you are unsure about the effective dates and their implications, consult the relevant SAP documentation or your organization's guidelines on data entry for the specific module you are working with.
  Seek Help from SAP Support: If you believe that the error is occurring incorrectly or if you need further assistance, consider reaching out to your SAP support team or consulting SAP Notes for any known issues related to this error message.
