Flatten Hierarchy By Filtering Out Unnecessary Limbs

Question

We have numerous hierarchies in our organization that faciliate various reporting views.  Some of those views are slight variations of one another.  One common theme that we have encountered is the need for the same basic view, but with less granularity in terms of rollups.
Example (alphas are limbs, numerics are leafs):
Master Hierarchy
A
     B
          C
               1
               2
          D   
               3
               4
     E
          5
          6
We need to derive a custom export that eliminates all the in-between nodes and just rolls all the leafs up to Node A.
A
     1
     2
     3
     4
     5
     6
This type of flattening may happen at any level within the hierarchy (not necessary all rolling up to the top level).  So we need a somewhat dynamic way to achieve this.  I am thinking that a property could be built to flag certain key levels that are required for the custom export, but still not sure how to get those key levels flagged as parents for the leafs, regardless of which level the leaf is at in the Master hierarchy.
Any thoughts?    

Answer 1

Hi Denzz,
What kind of OR condition could be written that would not only filter certain limb nodes out, but also realign the parent/child relationships accordingly.  For example:
Master Hierarchy
A
     B
          C
               1
               2
          D   
               3
               4
     E
          5
          6
We need to derive a custom export that eliminates rollups C & D.
A
  B 
     1
     2
     3
     4
  E 
     5
     6
I can understand creating a formula/property to filter in or out certain rollups.  But we would also need to effectively change the parent value of 1, 2, 3, 4 to B (instead of C or D).  Are you suggesting a formula that checks the immediate parent for the filter property, and if not found, then go to grandparent, then next grandparent and so on until found?
