Current Year vs Previous Year with a filter

Anonymous — Sat, 12 Mar 2016 14:35:21 GMT

Hi,

I have a problem about set analysis.

In attached sample data.

I have a calendar with two years - 2014 and 2015.

I want to sum, for the selected year - 2015, an Amount for months with a flag = E -> sum({<Flag={'E'}>}Amount) ->OK!

For the previous year (respect to the selected one) I want to sum the Amount for the same months of the selected year - if they exist - disregarding the flag.

Thanks!

max year

sum({$ <YEAR={$(=max(YEAR))}, FLAG={E}>} AMMOUNT)

and max-1 year

sum({$ <YEAR={$(=max(YEAR)-1)}, MONTH=P({$ <YEAR={$(=max(YEAR))}, FLAG={E}>} MONTH)>} AMMOUNT)

Thanks, it's correct.

Can you explain me how to manage the situation in which there are more customers?

In attached new data with two records about Customer B.

In my example, Ammount of customer B must not be included in the sum baceuase he has not flag E for current year. So the results must be the same (97 and 44).

I would like the calculation takes into account the situation of single customer and not globally.

So I want to consider, for each customer:

- Current Year: ticket with flag =E;

- Prevoius Year: ticket of the same month of current year disregarding flag.

and then sum all available Ammount.

Thanks!
