I submitted a file to the sandbox yesterday afternoon (Tues 7th) which was successfully validated (For Billing Date = '120100' and Period Number = '04').
I then submitted the exact same records in another file this morning but this time for February Period 2 (i.e. Billing Date = '120200' and Period Number = '01'). This second file had a number of validation errors relating to ISC Allowed/Accepted on RM Coupon Breakdowns (SFI 32).
E.g. "Accepted ISC amount does not match with Accepted ISC percentage * Gross Amount".
I don't understand why we are getting these validation errors when:
A. The amounts are actually correct
B. Aside from the Invoice Headers, the records are exactly the same as those that were successfully validated yesterday.
Can you shed some light on why the records were validated yesterday but rejected today? Are there any issues with file submission around the time of change in billing month/period?
Thanks in advance for your assistance.
