Grouping / Sorting of Node Elements

Hi all,

I'm currently writing a report in which I have to display after grouping some elements in the node.

For example following are the fields in the node:

Material, Plant, material document, doc year, movement type, storage location

Output desired is:

Material1 Plant1

storage location, movement type, material document, doc year

storage location, movement type, material document, doc year

...

Material1 Plant2

storage location, movement type, material document, doc year

storage location, movement type, material document, doc year

...

Material 2 Plant 1

storage location, movement type, material document, doc year

storage location, movement type, material document, doc year

...

How do I group the elements in the node in this manner.

I would really appreciate if you could provide me with an example ( if possible)

Thanks and Regards,

Jo
