Question:
Hi friends,
I request you to help me with the difference between Text, internal and external hierarchies by giving some examples. In one of the BW books, it is said that external hierachy objects do not reside in infocube. I am getting confused. The books also define different types of hierachy whereas SAP materials do not specify them.
Secondly, I read that loading hierachy data from flat files is tricky. Can some one tell what is the issue involved?
Thank you.

Answer:
Search [url]service.sap.com[/url] for the document on Multi-dimensional Data Modeling, it should answer your initial questions.
The issue with loading hierarchies from a flat file is that the file structure is so complicated. See 'Uploading Hierarchies from Flat Files' at [url]help.sap.com[/url]
