Pension Opt Out Refund - Across Tax Years Merged

Hi Team,
Currently if an employee is auto enrolled into a pension scheme in March, and then opts out prior to the April payrun the contribution refund will not automatically be generated as it is across tax years.

There is no warning that the refund has not been generated, so luckily we manually checked, whereby we then had to create a pay code to refund the employee.

Also issue is the pension reports will not be reflected correctly for EE & ERs contributions, as the pay code refund will not be considered as pension within Staffology.

The reason provided by support was that they cannot have a negative pension figure on the FPS file, can this just be sent as a zero?
