What this means: Your data doesn't include an employer identifier, so Jarvis can't match it to the right scheme.
Why this might happen: The employer reference field is likely not configured in your payroll system's pension export settings.
What to do
Check that the employer reference is configured in your payroll system. The field varies by format:
EmployerIdfor PAPDIS,Employer Referencefor NEST,ER CODEfor NOW:Pensions,Pension Companyfor Access Pay & BillIf you're unsure of the correct value, contact Jarvis Support
