Previously the financial year was calendar year and so Jan 15 was set up as Year 2015, Period 1 and so on, so Dec 15, was Year 2015 Period 12. However the financial year has changed to ending on 31 March, instead of 31 December! is there a way I can set my table up that when I ask to attach data to a table, it asks me to assign Apr 16 to Mar 17, that it attaches Year 2016 Period 4 to 12 and Year 2017 Period 1 to 3, just that I find I have to create 2 separate queries! Any ideas?
