i write to you because I have a problem i'd like to resolve.
I have some date, which belong to a fiscal integer, but the fiscal integer is not a date itself but an integer. (example: 1st april 09= 86, 1st april 10 = 87). this fiscal integer is invremented every april 1st.
However, not all the dates are used so not all of them are linked to the fiscal integer.
Is there a way to link them to the corresponding integer?
I wanted to try intervalmatch but it doesn't seem to work the way I want.
