Field help (FISAMT) 

The fiscal value of the goods corresponds to the amount of the journal lines, to which it is possible to add the invoicing elements, if their setup is aimed at being a part of the fiscal value calculation. These elements are distributed depending on how their distribution over the lines is set up. The non-distributed elements over the lines are distributed in proportion to the amounts of the line with respect to the total of the journal (if the total of the journal is not equal to 0).

This value is converted into the company's currency (instead of the journal's currency) using the rate type defined by the setup of the TC chapter, CDF group: EECTYPCUR - EU currency rate type, and the rate at the date of the journal.
