Veterans Employment - Armed Service Employees

The current system does not perform as expected or desired when employing a Veteran, in the first year there should be no ER NI costs. I have created a test payroll and a veteran employee. The system is calculating and reporting ER NI for the record. I have searched the system and contacted the Support Desk and there are no guides written and nobody can explain or document the functionality that the system should perfom. Can you please create a guide which detasils all actions required and how the system calculates and offsets the ER NI and how a reminder is triggered by the system as the 12 month limit is reached/ breached. This is paramount as my organisation is heavily involved with veteran recruitment.

Currently the system does not meet expected standard for this employment type.
