"ActionAddToCover" is an out-of-the-box activity that adds child case to parent case. I found an out-of-the-box flow action "Work-Cover-.AddToCover" which calls this ActionAddToCover activity and these works fine for one of our scenario - User opens parent case on screen and specify child case's pzInsKey.
Now, we need to build second scenario - user opens child case on screen and specify parent case's pzInsKey. So instead of parent to child, this is child to parent approach. In order to implement this, is there any out-of-the-box activity?
