derived types for measures for diff in yesterdays sales - 2 days ago sales

[mhamlett]

va 7.3

i am pulling sales from a data source that contains a date and sales amount.

i want to show the sales from yesterday with increase/descrease amount over the prior week/same day sales amount

ex.  today is 06.15

i will show sales for 06.14 (tuesday) compared to sales 06.07 (tuesday).

trying to use derived item but no luck making this work.

month works cannot get the calculation to work with a day.

using inferred  and -7 on the previous side of the calculation.

Hi mhamlett,

Have you tried to use the intck function?

data test;
days=intck('day','10jan16'd,'01jul16'd);
put days;
run;

With this function you can specify days, months, weeks... Using this function should be easy identify the dates comparing with actual day.

I usually take the actual day with 

%let today	=	%qsysfunc(date(),yymmdd10.);

sorry, but what you are suggesting does not exist in the VA product under creating a calculated measure or aggregated measure.

If you want to do that in SAS VA - just use the TreatAs function.
