Hi Mahender,
We do not have the option of loading a hierarchy in BW or ECC. Data is already loaded into the Cube but the Material Numbers are split in the records .One Material may actually have several material numbers that BW Query needs to aggregate into ONE Material so that the result is shown in one line.
For example:
ZZ88A-C1/01
ZZ88A-C1/02
These are two material numbers but they both need to be reported in one line under Material number ZZ88A-C1A.
I hope this clarifies your queries.
Cheers
Dan
