老师你好,麻烦修改一下应付采购发票付款汇总表的窗口按钮代码:

出错如下:1,当月采购  金额 未能按供应商统计,201512 阿三磨床  数量1000 /金额50000

            2,付款统计出错:当月201512 张三/100 
                                      201512 赵六/200 
                                      201512 李四/300 
                                      201512 王五/400

                                        合计 1000
