My requirement is when user gives 0i_calmo as selection field variable,report output should show closing stock for the same month and opening stock is the previous month's data fro the current month.
ex: selection field is- 04.2015 to 06.2015
04.2015 05.2015 06.2015
Result should come opening stock - 100 200 300
closing stock - 200 300 400
and for both opening stock and closing stock i am taking 0totalstock as keyfigure.
