If you encounter the above error message while attempting to issue a manual payment in the portal, there are two potential causes:
The NI Breakdown area in the manual payment has not been fully completed.
A row has been added to the "Manual Payment Pay Codes" area in the manual payment for Employee NI or Employer NI, but it contains a zero value.
To resolve this issue, you need to:
Ensure that you have completely filled in the NI Breakdown area in the Manual Payment, including the LEL field. If no values are due, enter a zero ("0").
If no NI is due, do not include a row with a zero value for NI in the Manual Payment Pay Codes area on the Manual Payment screen
