Summary:
The error message "Timesheet Validation Rule cannot be empty" occurs when a validation rule is not setup in Web TimeSheet and if the administrator accidentally clicks on the 'Add Validation Rule' button under the 'Advanced' tab of a user profile and navigates to a different tab to edit various other settings (like Time Off, E-mail) and then clicks on the 'Save' button for the changes to take effect.

Cause:
When there is no validation rule setup in Web TimeSheet and upon clicking the 'Add Validation Rule' creates a new row with empty 'Start Date', 'End Date' and 'Timesheet Validation Rule' fields. This row remains active even after navigating to a different tab and upon clicking on the 'Save' button to save the user profile, the error message appears notifying the administrator as the Timesheet Validation Rule cannot be empty".

Resolution:

  • Click the Advanced tab under the user profile.
  • Scroll down to the bottom of the page to look for the Timesheet Validation Rule option.
  • Click the Delete button (the Red 'X' icon) next to the new empty row of validation rule that was added to the user profile.
  • Save the user profile.
