What is the build method to be used in this scenario

Question

A
B --- C ---d ----e ---f ---g
X ---Y---Z
here A is parent and B,X are childs of A, and C,D,e,f,g, are childs of B, and Y,Z are childs of X then what the build method we must take,when and how do we choose the build methods, is it depending on the hierarchy or what

Answer 1

Per Glenn's post, you could use a generation load rule against the records for B and X, skipping the first record altogether to come up with the descendants of those two members.
But that wouldn't get you the relationship of B and X as children of A.
That's why I wrote you have a mix of dimension build types in your file, or maybe more accurately, an incomplete build file.
A generation build would look something like:
A, B, C
A, B, d
A, B, e
A, B, f
A, B, g
A, X, y
A, X, z
A parent/child build would look like:
A, B
B, C
B, d
B, e
B, F
B, g
A, X
X, y
X, z
Neither approach matches what you have. Again, I see the parent/child layout most often but maybe that's just me.
You could play games like first applying a parent/child build rule against your existing layout (with a little tweaking), and then maybe multiple build rules against the file/table for the generation appproach but that seems awfully complicated. Why not just get the source format into a decent format.
