Adăugarea mai multor parametri în raport
Anterior, ai adăugat un parametru pentru country pentru a crea rapoarte noi care să rezume informații despre proiectele de investiții pentru orice țară din datele investment_services_projects. Acum, vei adăuga parametri pentru anul fiscal și vei modifica codul existent, astfel încât să poți genera rapoarte noi despre proiectele de investiții pentru orice combinație de țară și an fiscal din datele investment_services_projects.

year_startșiyear_endpentru date, folosind2017-07-01pentruyear_startși2018-06-30pentruyear_endale anului fiscal 2018. - Înlocuiește referințele la date din funcția
filter()de pe liniile64și65cu referințe la parametriiyear_startșiyear_end. - În blocul de cod
country-investment-projects-2018, redenumește blocul încountry-annual-investment-projectsși actualizează numele obiectului și referințele la acesta din text cucountry_annual_investment_projects.
