Hello PwC,

In the Posted Transaction file, prior year postings have a fiscal period between 1 and the number of periods in the fiscal calendar (1-12 in a 12 period fiscal year). Current year postings have fiscal periods offset by the number of periods (13-24 for periods 1 to 12 in a 12 period fiscal calender).

You can isolate all the prior year transactions by a filter that selects only those transactions with a period < 13 for a 12 period fiscal calendar.
