Products have specific ingredients
For instance a blouse is made by 3 materials fabric, a zip and a thread:
| 
					 1 2 3 4  | 
						 Code   Item     Measurement unit  Fbr    Fabrix   meters  ZIP    ZIP      PIECES  THR    Thread   meters  | 
					
At the analytic description, the blouse is the final product so we write:
| 
					 1 2 3  | 
						Fbr=2 ZIP=1 THR=100  | 
					
Which means that we have used 2 meters fabric,1 zip and 100 meters Threads.
On the left field there is the code of each product and on the right the quantity.
