系统中有前台服务器和后台服务器，前台的销售数据是直接传到前台服务器的，而后台是通过作业定时从前台获取销售记录的。分析原因：
1 后台定时执行没有执行，由于数据库的代理服务没有启动或者人为的将作业停了，导致后台定时执行没有执行；处理办法，启动作业，开启数据库代理的服务
2 销售拆分问题：销售数据传到后台后，系统会进行拆分，拆分完成后，才会在相关报表中体现，才会真正算销售。销售拆分出错是绝大多少销售没有传到后台的原因。导致这样的情况一般有下面几个情况 1、有人修改tb_trans_status，导致记录已拆分记录错误 处理办法：修改 tb_trans_status中销售拆分的id,可以找最大tb_o_sg.c_identity；2、前台硬件故障，销售重复传送，特征：tb_o_sale.c_guid重复处理办法：删除重复的c_guid；3、商品后台不存在，这个一般由于后台删除商品后，没有及时传到前台，前台正好做了销售，处理办法：删除改流水，用正确的商品编码销售；4、商品在一个门店存在2个部门，销售拆分时不知道是哪个部门算哪个部门的销售，处理办法：删除错误的部门。
辅助查询语句：
/*tb_o_sale.c_guid重复*/
select * from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='销售分拆')
and exists (select * from tb_o_sg (nolock) where tb_o_sale.c_guid=tb_o_sg.c_guid)
/*一个商品在一个门店存在2个部门*/
select c_store_id,c_gcode,COUNT(*) as c_count
from(
select tb_o_sale.c_gcode,tb_gdsstore.c_store_id,tb_gdsstore.c_adno
from tb_o_sale(nolock),tb_gdsstore(nolock)
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='销售分拆')
and tb_o_sale.c_gcode=tb_gdsstore.c_gcode
group by tb_o_sale.c_gcode,tb_gdsstore.c_store_id,tb_gdsstore.c_adno
)a
group by c_store_id,c_gcode
having COUNT(*)>1
/*商品编码后台不存在*/
select * from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='销售分拆')
and not exists (select * from tb_gds (nolock) where tb_o_sale.c_gcode=tb_gds.c_gcode)
and c_flag='G'
还有一种：
select c_guid from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='销售分拆')
group by c_guid
having count(*)>1
还有一种情况，没有可用的资源了，比方磁盘空间或者内存设置过低 或者本身服务器内存就比较小
导致服务被终止，传输无法运行，我这出现过类似的问题
处理方法：
1 先将数据做好备份
2 删除重复数据
3 观察作业是否成功
以/*tb_o_sale.c_guid重复*/为例：
第一步：
select * into tb_o_sale_20110815
from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='销售分拆')
and exists (select * from tb_o_sg (nolock) where tb_o_sale.c_guid=tb_o_sg.c_guid)
第二步：
delete from tb_o_sale
where c_identity>(select isnull(c_id,0) from tb_trans_status where c_proc='销售分拆')
and exists (select * from tb_o_sg (nolock) where tb_o_sale.c_guid=tb_o_sg.c_guid)
第三步：
查看作业是否成功，实时销售监察是否正确
如果不想让错误数据影响当天销售，可以建立作业，将错误数据做好备份，让剩余数据正常拆分，建议一天晚上执行一次
