下面是我们在开发合并报表时遇到的坑，自己研究了很久，期间不在上下文里，后台一直看，才发现在iCalculateContextProvider这个接口里；期间的：年，月，开始日期，结束日期，都有了

IReportPropertyAdapter reportAdapter = iCalculateContextProvider.getReportAdapter();

String year = String.valueOf(reportAdapter.getReportProperty("report.year"));

String period = String.valueOf(reportAdapter.getReportProperty("report.period"));

String report_startdate = String.valueOf(reportAdapter.getReportProperty("report_startdate"));

String periodEndDate = String.valueOf(reportAdapter.getReportProperty("report_enddate"));
