Current year Previous Year in Query

Question

Hi,
I have to get the results of current year 12 months( 12 columns) previous year 12 month( 12 columns) in one report.
Once the user gives the current year , how to automatically populate the previous year. The PY varaint can be used for all months of previous year.
Any thoughts on this, please let me know.

Answer 1

As venkat said , using offset is the best option, rather than jumping directly to custom exit variable.
for e.g.
you report display is
net qty.............net qty
current year......  previous year........
bil1
bil2
so u intend to see the net quantity for current year and previous year.
Bring net qty... in Columns in query designer.
Now right click and hit Edit
Now bring in time chara. that u wish to use and want to create variable for.................
for e.g. say fiscal period....
Now hit fiscal period with right click andhit  Restrict.
Go for Interval variable if already exist or else create a new one.
hit okey..
now in query designer in columns copy ur net quantity
now paste there again.
in Second net quantity u can hit edit.
now where fiscal period is there hit restrict
in dialog box hit Select offset.
As ur intention is for previous year, keep the offset value as -12
also restrict fiscal year variant in selection.....
hit okey
test it...
if this doesnot work
then go for custom exit....
