When we create a sales/purchase transaction and add the usage unit while adding quantity for any particular line item, the usage unit always comes below the quantity.

What this effectively does is that the number of rows consumed is always double (As the usage unit would always consume one row per item added).

This becomes very problematic when the number of items in a transaction are huge, lets say around 40-50 items. In such cases, the rows for items are 80-100 instead of 40-50 and this leads to a lengthy invoice PDF. While this doesn't look good aesthetically, it also means a lots of paper waste. 

Please look into this and provide a solution. Two good ways to handle this could be either to add another column for the usage unit or to add the unit beside the quantity instead of below it.

Thanks,
