Authorization doubt in hier

Hi,

Have a plant hierarchy.

In R3,

1231  00  01 DR01

-> 1222  00  01  DR01

   -> 2100  00  01  DR01

-> 1223  00  01  DR01

Eg: plant -> 1231, Div -> 00, Channel -> 01, Sales org -> DR01

Now in BW, Plant is authorization relevant, it got Div, Channel and Salesorg as Compounding attr. Hence the HIER appearing as below:

00/01/DR01/1231

  -> 00/01/DR01/1222

    -> 00/01/DR01/2100

  -> 00/01/DR01/1223

• If I want to use the node authorization in reports, is it enough if I add plant authorization variable in filter section of reports? Or even the compounding attr should be authorization relevant and should they also be added in reports?
