Title: placing year on the report based on selections made by the user [static choices
Post by: meher28 on 20 Jul 2010 07:44:03 AM
hi Guys,
           This is my first post, and also I am new to Cognos... please guys help me out...

I got a question in cognos report studio

If am not using any tables and if i create a value prompt with two static choices [say current year and previousyear] and if user selects current year in
prompt page application should display like Select Year is : 2009
[Text Item] Select year : <layoutcalculation>

but the question is how do i put the calculated expression in the layoutcalculation on the report....
[like for current year/date : today() and for previousyear/date : _addyears(date2timestmp(today()),-1)] but where and how do i assign these variables in the layout calculation on the report... 
thanks
meher28

I am not getting what is ur question but what i have understood based on post is it should diplay if the user selects current year i.e.,2010 then he should get
Select Year is : 2009
try this

(text item)Select Year is : <case when paramvalue(?date?)= 'sysdate' then
_add_years(sysdate,-1) else ?date? end>

SORRY ABOUT IT [i admit i was not clear]

In the prompt page I have a value prompt [with static choices] --- Current Year and Previous Year
If the user selects current year

application/report should display value on the report [any where like page body/header like

Selected Year : 2009
[Text Item] : <Layout Calculator>

So where do i place the expression i mean in layoutcalculator expression or where?]
