in reply to Putting contents of an array into Object property

Your $self->{clientorgunit} is a refernce to an array, so you need to deref it to make it an array before you put things into it. You could do it either as:
@{$self->{clientorgunit}} = @items_to_put;
Or, better, if you are continuing to add items to it:
push @{$self->{clientorgunit}}, @items_to_put;

It's not what you know, but knowing how to find it if you don't know that's important
