Hello,
In our current model, we have an existing hierarchy with let's call A and its child B. We want to add a new hierarchy list as X, and X will be the parent of A. As far as I know, adding a top hierarchy list should not cause any issues for the current modules with list A and list B dimensions and shouldn't ruin any existing functionalities, but I want to hear from fellow model builders if there is any issue I need to aware of or anything I need to do beyond adding the new hierarchy member. Thanks
