I have a database of benefactors. For example if i have Benefactors A and B and beneficiaries C and D. A used to send Donation for C and D every year. If i want to show a portal of benefactor A which shows the total donation of a year and that year. Means If A sent donations in 2017 five times i wanted to show the portal 2017 + (total donation of 2017). same for each year. I have portal which shows all the donation of A but i need to sort by year. How much donation received every year.
