自定义报表报路径错误

如果彼此

自定义的报表数据源，设置主表的时候会直接报路径的错误，业务字段没有重复，同时我想问一句主从报表可以同一行吗，不行的话，这个问题也不用解决了选择节点失败，xpath：dataset('reportMainData_master')/FID/recordcom.justep.report.exception.ReportServerException: 选择节点失败，xpath：dataset('reportMainData_master')/FID/record

同一个不能写两个data的select

如果要在一行显示就在sql中用关联查询的方式，返回的同一个table中，用一个data操作
