hi,
I need make a sum over several periods chosen by user (in the format YYYYMM) and represent the sum for the parallel periods from previous year.
Ex.: if the user chooses 201803 & 201703, I should be able to represent sum for these 2 periods and sum for 201703 & 201603,
where previous period for 201803 is 201703, and previous period for 201703 is 201603.
Any ideas how that can be done?
Many thanks,
Anastasia
