Hello all,
We are having a Hierarchy 'A' (existing) which is considered as a Master hierarchy and we are planning to create a hierarchy 'B' as a alternate based on the master hierarchy 'A' plus few additional nodes in hierarchy B.

CURRENT STATE: When we add leafs like highlighted in hierarchy B, it automatically adds those leafs in hierarchy A also which we do not wanted to happen. For example, the leaf nodes (leaf_33333333A, ***B and ****C) should be present ONLY in hierarchy B and NOT be flown into hierarchy A.
EXPECTATION / TARGET STATE:
> We want to keep the hierarchies A and B as it is displayed in the above diagram.
> Any new limb or leaf added by users in Hierarchy B (alternate) should stay in Hierarchy B ONLY.
> But, Any new limb or leaf added by users in Hierarchy A (Master) should reflect in Hierarchy B also.
NOTE: To create the same nodes in hierarchy B, 'Insert' option was used. Also note, the new leafs to be added in hier B (but not to reflect in hier A) can be added at any level.
QUESTIONS / HELP REQUIRED:
> How can we break the "backward flow" relationship from hierarchy B to hierarchy A ?
> However, we want to retain the "forward flow" relationship from hierarchy A to B so that any nodes added in hierarchy A gets reflected in hierarchy B also.
Thank you in advance.
