+1、com.huazheng.project.greenplum.service.impl.JobServiceImpl.selectSysSAPreturnNoNew()
+1、com.huazheng.project.greenplum.service.impl.JobServiceImpl.selectSysSAPreturnNoNew()
+2、sapNo需要补0
+<select id="selectSysSAPreturnNoNew" parameterType="SysSAPreturnNo" resultType="SysSAPreturnNo">

+	select id as rowids,
+		id,processName,shiLiH,sapNo,chuangJianSJ
+	from Sys_SAPreturnNo

+</select>
+
+select * from SysSAPreturnNo where sapno = '10059162';
+select * from SysSAPreturnNo where sapno = '0010059162';
+
+com.huazheng.project.greenplum.service.impl.CheckUpdateServiceImpl.selectVbapCheckUpdate()
+SalesContractProcess salesContractProcess = gpMapper.selectVbapAdv4SalesContractProcess(source); // vbap-SysSAPreturnNo-SalesContractProcess
+if (salesContractProcess != null) {
+	salesContractProcess.setVbap(source);
+	gpMapper.updateVbapAdv4SalesContractProcess(salesContractProcess); // vbap-SysSAPreturnNo-SalesContractProcess
+}
+
+gpMapper.selectVbapAdv4SalesContractProcess(source)
+select b.* from SysSAPreturnNo a
+left join SalesContractProcess b on a.processName = b.SYSPROCESSNAME and a.shiLiH = SYSINCIDENT
+where b.id is not null and a.sapno = #{vbeln}
+limit 1
+#{vbeln}这个参数是vbap的vbeln，是有前面两个0的
+
+select * from SysSAPreturnNo where sapno = '0010059162';
+
+select a.sapno,b.* from SysSAPreturnNo a
+left join SalesContractProcess b on a.processName = b.SYSPROCESSNAME and a.shiLiH = SYSINCIDENT
+where b.id is not null and a.sapno = '10059162'
+limit 1
+
+select a.sapno,b.* from SysSAPreturnNo a
+left join SalesContractProcess b on a.processName = b.SYSPROCESSNAME and a.shiLiH = SYSINCIDENT
+where b.id is not null and a.sapno = '0010059162'
+limit 1
+-----------------------
+
+
+处理方案
+1、sapNo需要补0
+HzcrmMapper_mssql2.xml
+selectSysSAPreturnNoNew 拉数据用的com.huazheng.project.greenplum.service.impl.JobServiceImpl.selectSysSAPreturnNoNew()
+selectSysSAPreturnNoById 删除时候 com.huazheng.project.greenplum.service.impl.CheckDeleteServiceImpl.selectSysSAPreturnNoCheckByDelete()
+cascadeSysSAPreturnNoByVbap 和vbap级联更新的时候com.huazheng.project.greenplum.service.impl.CheckUpdateServiceImpl.selectVbapCheckUpdate()
+('00'+sapNo) as sapNo
+
+2、数仓SysSAPreturnNo表里面的sapNo字段的现有的数据补0
+--update SysSAPreturnNo set sapno = '00'||sapno where "length"(sapno) = 8;
+
+3、调试vbap的更新，代码块
+调整vbap的update计数器 
+set huazheng:checkUpdate:Vbap:rowids 0
+update vbap set hashresult = null;
+
+com.huazheng.project.greenplum.service.impl.CheckUpdateServiceImpl.selectVbapCheckUpdate()
+SalesContractProcess salesContractProcess = gpMapper.selectVbapAdv4SalesContractProcess(source); // vbap-SysSAPreturnNo-SalesContractProcess
+if (salesContractProcess != null) {
+	salesContractProcess.setVbap(source);
+	gpMapper.updateVbapAdv4SalesContractProcess(salesContractProcess); // vbap-SysSAPreturnNo-SalesContractProcess
+}
+
+select b.* from SysSAPreturnNo a
+left join SalesContractProcess b on a.processName = b.SYSPROCESSNAME and a.shiLiH = SYSINCIDENT
+where b.id is not null and a.sapno = #{vbeln}这个是vbap的vbeln是带0的
+limit 1
+
+就会进入updateVbapAdv4SalesContractProcess
+update VbapAdv set
+	scp_id = #{id}, scp_xiaoShouDDBH = #{xiaoShouDDBH}, scp_xuFangGSID = #{xuFangGSID}, 
+	scp_xuFangGS = #{xuFangGS}, scp_gongFangGSt = #{gongFangGSt}, scp_xiaoShouBMt = #{xiaoShouBMt}, 
+	scp_shouHuoGSID = #{shouHuoGSID}, scp_shouHuoGS = #{shouHuoGS}, scp_fuKuanTJt = #{fuKuanTJt}, 
+	scp_caiGouDDBH = #{caiGouDDBH}, scp_dangQianXYED = #{dangQianXYED}, scp_yvQiK = #{yvQiK}, 
+	scp_dengJi = #{dengJi}, scp_biZhongt = #{biZhongt}, scp_yongJin = #{yongJin}, 
+	scp_zongHeMLL = #{zongHeMLL}, scp_sysProcessname = #{sysProcessname}, scp_sysIncident = #{sysIncident},
+	scp_ziShiYBv = #{ziShiYBv}
+where vbeln = #{vbap.vbeln} and posnr = #{vbap.posnr} and mandt = #{vbap.mandt} and erdat1 = #{vbap.erdat1}
+
+
+
+问题的解释
+1、宽表在更新字段时候，比如更新宽表中SysSAPreturnNo表的字段，首先表关联逻辑没有问题
+2、造成宽表字段没有更新到值是因为源库中SysSAPreturnNo.sapno存储的时候缺少00，vbap的vbel是10位的是有前置00的
+3、在更新vbap宽表的时候需要根据关联条件vbap.vbeln=SysSAPreturnNo.sapno去查询数据
+4、但是由于vbap.vbeln、SysSAPreturnNo.sapno两个字段的值的位数同步，导致查不到数据，所以没有更新到宽表中SysSAPreturnNo表的字段
+
+我们现在的处理手段
+1、在查询源库SysSAPreturnNo表的时候进行补0，然后再写到数仓中的SysSAPreturnNo表中
+2、写好之后调试vbap的更新流程，发现vbap.vbeln=SysSAPreturnNo.sapno关联的时候已经没有问题了，可以查到数据了，从而宽表的SysSAPreturnNo表的字段就被更新上了
+
+
+
+vbap更新流程
+1、先从源库中取20个数据（计数器）
+2、对比数仓的数据，计算源库数据的hash值，对比数仓中的数据的hash值
+3、如果一致，就不用更新了
+4、不一致，开始更新
+4.1、更新vbap表
+4.2、更新vbap宽表
+4.3、级联更新（数据同步类型.xlsx）更新的是被vbap级联到的表
+4.4、更新计算字段
+4.5、更新宽表中的附属表字段
+4.6、结束
