使用wiki末尾的report 通过 bol entity的 set_property 修改一个service order的description，在SAT里面能够看到下列callstack:
1. 从container proxy拿到attribute property object ( line 16 )
2. 从object model根据attribute name和当前BOL entity的object name拿到attribute index( line 18 )
3. 判断当前待修改的attribute是否满足修改条件: 非read only, 且BOL entity是changeable( line 23 ~ line 24 )
4. 判断当前的attribute value是否等于待修改的新value ( line 25 )
5. 如果bol entity没有上锁，则call lock method ( line 29)
6. 将changed flag置位( line 34 )
7. 将bol entity的sendable flag置位( line 37 )
8. 在buffer里将attribute设成set_property传入的值( line 40 )
9. 记录change log ( line 43 )
在bol entity manager GET_MODIFIED_ENTITIES里:
只有在set_property里面调用了activate_sending的entity才会返回.
设置断点:
通过debug的方式能发现如果通过 set_property修改description，则传到function module CRM_ORDER_MAINTAIN里的参数只是order guid + new description value:
