Hi Deepika,
Thanks for replying.
Now I have 2 issues about it
1. The "Create_follow_up" method is implemented in class CL_CRM_UIU_BT_H_OVW_VIEWSET. This is the super-super class of my component. This is standard class and I can't change it.
2. I tried to change the value from "A" to null in debug mode, and found that the newly created doc flow misses many values. It should inherit some attributes from parent transaction(Defined in copying control.)
Any experience about it?
Thanks
Alice
