BAPI_PO_CREATE1
1.报错：客户xx不在工厂xx中
原因：填错了抬头中的 供应商、供应工厂，项目中的供应库存地点
报错：06 218，净价格必须大于0 et price must be greater than 0
原因：
1.没有自动带出净价（维护供应商条件价格），或者带出的采购信息记录价格不大于0
2.多次调用缓存问题，清缓存
**清空缓存
* perform mepo_refresh(saplmepo).
* data: mem_optn like csdata-xfeld value '0'.
* export mem_optn to memory id 'CSIO_MEM_OPTN'.
2.有多个外协消耗组件时报错
Change indicators could not be uniquely determined in material mapping
原因：没有填 pocomponents-item_no
删除自动从bom带出来的外协组件的方法：参考 lg zflg_po_create
pocond-change_id = 'U'.更新价格，I表示新增价格（I新增价格时先加一行D删除采购信息记录的价格）
pocondx-change_id = 'X'.
3.
ls_poheader-item_intvl = 'X'. "项目编号间隔
ls_poheaderx-item_intvl = 'X'. "项目编号间隔
必须传这两个参数，不然行项目不支持指定项目号
4.供货工厂是根据供应商取的，如果供货工厂不对会报错“净价计算错误”
5.Numerical entry is not supported for extrnal item（外部条目标识不支持编号条目），行项目号问题，比如项目号传重复了
6.UB转出单报错：06 215 请输入净价格。
原因：item传了GT_ID IR_ID
7.no_price_from_po = 'X' 不带用户的价格过来，但是会带采购信息记录
可以删采购信息记录，也可以item-po_price = 2,这样就不会带采购信息记录了，但要注意，如果item里写了采购信息记录（比如先跑了testrun返回进item了），就删不掉了。
注意事项
1.创建po带过来多个重复的价格
原因：配置问题，用户参数 EVO
或 no_price_from_po = 'X' 不带价格过来
2.如果物料维护了舍入值，则生成的采购订单的数量可能和传入的值不一样
比如舍入值为30的时候，传入100会生成120的订单
3 如果有采购信息记录，会自动带出价格条件，此时如果chang_id = 'I'，会在原来的价格条件的基础上再加一条条件
正确的做法应该是，先传一行D，再传一行 I
4 转储采购订单没有库存也可以创建，但是创建交货单就会失败了（可用库存，不是非限制使用库存），可以先用BAPI_MATERIAL_AVAILABILITY检查可用库存
5.物料有多个单位，生成的采购订单单位和传入的单位不一样，并且自动转换了数量。
修改采购信息记录的订单单位之后就可以了。
