Roti/Dhal Puri Dough

Can anyone tell me if the dough that is made for roti (regular paratha or oil roti as we say) is the same dough that is kneaded for dhal puri? I'm asking because when I make dhall puri with the same mixture I use for roti, the finished product does not feel or look the same like the ones we would get from a snackette or other people who make it regularly - which is usually paper thin.
