You need to provide more information. As I understand your problem, you want to create a structure that could be made manually like this

push @{$hash{globalkey}{key2}{key3}{key4}}, 'ARRAY VALUE';
push @{$hash{globalkey}{key2}{key3}{key4}{key5}}, 'ARRAY VALUE';
#...

The first line wants the 'key4' entry to be an array, but the second line want that entry to be a hash.

Show some real data and tell us what output you expect.
