问题描述：

出纳付款单生成凭证时报错，提示业务脚本配置错误，第3行执行出错:

if((__src.entries.contractEntrySeq  == "-1"  ||  __src.entries.contractEntrySeq  == "-2") && __src.entries.contractEntrySeq != null && ( com.kingdee.bos.workflow.ext.app.Sql.getObject(__bosContext, "SELECT fnumber FROM T_BD_ACCOUNTVIEW where fid in (select floanaccountid from T_BC_ExpenseTypeSubjectMapping where fcompanyid='" + __src.company.id + "' and fexpensetypeid='" + __src.entries.expenseType.id + "')")).indexOf("2202")  <  0)  {formula_result = 0;   }

执行方法错误,找不到指定的方法.对象类型: com.kingdee.eas.fi.cas.PaymentBillInfo, 方法名称: indexOf,

解决方案：

SELECT fnumber FROM T_BD_ACCOUNTVIEW where fid in (select floanaccountid from T_BC_ExpenseTypeSubjectMapping where fcompanyid='" + __src.company.id + "' and fexpensetypeid='" + __src.entries.expenseType.id + "')这里查出来为空导致
