thanks for answering

so internal hierarchy is on time charecteristics like

0calday,0calmonth,0calyear

and

suppose we r creating hierarchy on 0material

in nodes we r using attributes of material like omatgrp,0indsect,0mattype

and

in external hierarchy we r using other info objects

correct me if i am wrong

Hi,

1) External hierarchies: these are hierarchies on characteristics. They are defined for exactly one InfoObject. They are tree-like structures.

--> This could be for instance a hierarchy loaded from R/3, but also any hierarchy created manually on an InfoObject.

2) Internal hierarchies:

a) Hierarchical structure determined in the InfoCube modeling. I.e. 0CALDAY, 0CALMONTH and 0CALYEAR already form a hierarchy in the time dimension.

b) In an InfoObject maintenance, a hierarchy can be mapped in the characteristic attributes. I.e. 0MATERIAL, 0MATL_GROUP, 0MATL_TYPE.
