Hi,
i have following problem.
I have following analisys:

The result is correct. Quantità YTD, for example for February Month is the sum of Quantity for January and February and so on. The total of Quantita YTD è 288.950.856
It should be the value of Quantità Ytd for Year 2017, but when i drop Month level, the result of Quantita YTD is :

instead 288.950.856
Strange thing is that the YTD is the value of December 2017.
I have setted my rpd hierarchy as following:

Anno level settings:

The anno field contains values 2010, 2011,2012,2013 and so on
Mese level settings:

The AnnoMese field contains the concatenation of the year with the month: for ex. 201001, 201104
The Mese fields contains values January, February, March and so on...
Giorno level settings:

The DataAS400 field contains values 20100201, 20110406 and so on.
What's the error on hierarchy? Can you help? It's quite urgent.
Regards
