The planning department has issued an office memorandum to secretaries and principal secretaries of all departments, asking them to furnish the details by November 7.
The move intends to ensure that there is no shortage of funds for the government-run schemes, programmes and projects in the national capital.
The memorandum said that the planning department has initiated the process of preparing the revised outlay 2017-18 for all schemes, projects and programmes.
"It is suggested that while projecting the requirement of funds for the remaining part of the year, a realistic view may be taken based on the expenditure upto October 2017 and a realistic requirement of funds upto March 2018," it said.
