Hello, unless you write a specific routine, you won't be able to load hierarchy text nodes as the members to Account dimension on BW level in any case.
And I reckon you won't be able to see any loading results in BPC anyway, until you run UJA_REFRESH_DIM_CACHE program.
I still would suggest you do all the screenshots of your BW->BPC loading process in the previous post and let us suggest solutions, because you might be missing something, without realising it.
In previous post you were using the "How to" from SCN. Just check your loads again using the classic document from Jeffrey Holdeman.
