如果想快速找出BDOC里error message是在代码什么位置抛出的：
最快的做法是在如下function module里设置断点:
找到引起错误的object ID:
找到125和126的父子关系:
IBASE 1268, 10000125 03.
When the first time initial download is performed, object structure 1268 is created, which is expected to connect 10000125 to 10000126.
这个问题是leading zero的转换引起的. pv_object_id不引起定义成text,而应该是comm_product-product_id.
