然后说几点问题：
一、首先是两个单位：
修改价格的时候，别把定价条件的单位给变了，
当然，具体根据需求来看
二、：
* L_SWITH-PRICING = 'G'. "定价类型 ：G：复制不变定价因素且重定税款
这个B C G具体取哪个值或者使用默认值可以参考：
双击行项目，点更新
三、 lt_conditions_inx -updateflag = 'U' .
这里更新标志是用U还是用I，
一般而言，U是修改原来数据，I是插入一条新数据
当然，有时候是修改不了价格的，
比如后台配置不允许手动修改价格等
当然，可以在创建的时候直接修改审批状态：
FORM frm_change_status
USING pv_vbeln

有时候，计划行数量没更新过来
到时候再自己调试下哪儿的原因，或者最笨的方法，录个bdc确认计划行就行了
