Hi Pawan ,
Good to see you have resolved few of the issues .
5. Now I got your issue . In "Copy Control Mapping" SPRO Node , mark inactive for Ibase column ie. Ibase will not be copied over from CR to Change Document . Then try it .
6. You want to hide 2 fields in the "Details" assignment block - is my understanding correct ? Hiding any UI fields can be done through UI configuration.
