UK Payroll: NI Adjustments

Summary:

I am attempting to make NI Adjustments for Employee and Employer. I am following the guidance in the UK whitepaper to make a balance adjustment using the seeded elements and marking them for payments and costings but when running payroll the changes are not actually applied to the payroll result i.e. the employee does not pay more or less NI as required

Content (required):

The scenario is that the client has lots of staff who start and stop paying NI as they work overseas. Sometimes a change is reported after payroll cut off so an adjustment needs to be made to either refund or deduct additional NI for the previous month.
