This error indicates that the system is trying to create a new time interval that does not align with the defined periods in the time management configuration.

  Use Correct Transaction Codes: Ensure that you are using the correct transaction codes for entering time data. For example, use the appropriate time entry transaction that respects the period boundaries.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to manage time intervals and periods effectively.
