Export closed transactions

Ok, in actions that have produced a sale of several purchases does not come out in the cvs file all operations but the general calculation, I can see the relationship of the purchases of that sale by pressing No. transactions in Info (a box with the relationship of the purchases of the sale but this is not reflected in the cvs file)
Do you know if there is a way to get all the information?, in Spain is necessary for tax filing specify amount, dates of each purchase transaction of a specific lot
Thank you very much.
