I completely agree with NikkiParsons comments above. On contacting Partner Support I was advised that there was a 'glitch' that had been rectified but I was required to re-process the entire payroll.
The payroll I was processing was in a heavily unionised industry so, in addition to the impacts outlined above, I was at risk of having an entire workforce (140+ employees) stood down, on full pay, until the payment hit the employees bank account. This would have reflected very poorly on my professionalism/reliability in my clients eyes and cost them a considerable amount of money. I whole heartedly agree that advance notice of any issues around the highly regulated area of payroll is imperative.
