You will get this error if there is time range overlapped issue.
Solution:
1. Please make sure this employee has clocked out.
For example: if this employee clocked at 8:00AM and has not clocked out, you cannot input the data for 8AM to 2PM.
2. Please check the timesheet if there is any overlapped.
For example: If there is a record for 8AM to 10AM, you cannot enter a new record for 9AM to 11AM.
Thank you,
