Hi Manojqlik,

The script is combining 2 fields to present a date in the dashboard like YearWeek, YearMonth etc.

To do this you need to combine fields.

Year(DATE) is creating a year from the date field.

right(’00′ & week(DATE),2)  is creating a week from the date field but is including 00 as prceding number. So you will get 2014(year)0010(week).

Is that clear?

your script

t:

load

'01/01/2014' + rowno() as DATE

autogenerate 365;

load

DATE,

Year(DATE) & right('00' & week(DATE),2) as YYYYWW,

Year(DATE) & right('00' & num(Month(DATE)),2) as YYYYMM,

Year(DATE) & ceil(num(Month(DATE))/3) as YYYYK,

'Quarter' & ceil(num(Month(DATE))/3) as QUARTER

Resident t

;
