Fiscal periods will be picked up as per the current system time. The current year will be the current fiscal period starting from 1st of April of the current year to 31st March of (current year+1). And it will also aggregate the data of one previous fiscal year starting from 1st of April of (current year -1) to 31st March of the current year.
As per the fiscal time periods, The below steps are required to aggregate the final fiscal event data.
Group the sum of amount based on project id, COA(chart of account) id, and event type.
Difference of sum of the amount of "DEMAND" and "RECEIPT" event type with respect to distinct project id.
