使用wiki末尾的report 通過 bol entity的 set_property 修改一個service order的description，在SAT里面能夠看到下列callstack:

?

1. 從container proxy拿到attribute property object ( line 16 )

2. 從object model根據attribute name和當前BOL entity的object name拿到attribute index( line 18 )

3. 判斷當前待修改的attribute是否滿足修改條件: 非read only, 且BOL entity是changeable( line 23 ~ line 24 )

4. 判斷當前的attribute value是否等于待修改的新value ( line 25 )

5. 如果bol entity沒有上鎖，則call lock method ( line 29)

6. 將changed flag置位( line 34 )

?

7. 將bol entity的sendable flag置位( line 37 )

8. 在buffer里將attribute設成set_property傳入的值( line 40 )

9. 記錄change log ( line 43 )

?

在bol entity manager GET_MODIFIED_ENTITIES里:

?

只有在set_property里面調用了activate_sending的entity才會返回.

設置斷點:

通過debug的方式能發現如果通過 set_property修改description，則傳到function module CRM_ORDER_MAINTAIN里的參數只是order guid + new description value:
