Cog.7 is thick client (the client has to be installed on 
your pc) where as Cog.8 is thin client (no client is 
needed , u can access thru webpage (url), But if the 
interviewer is looking for differnt answer, then say like 
this: Cog.7 is Window Based and Cog.8 is Web Based(except 
framework manager)

go for it, because using java scripts you can develop 
cognos reports which is not even possible by the existing 
GUI.

this is usualy a result of parsing a wrong data type i.e a 
string instead of a VARCHAR in the filters and the best way 
would be to trace where you passing values in your report 
in most cases it is on your filters or data items or 
calculations where you doing Case OR If statements :) also 
the syntax that one has used can cause a parsing error i.e 
syntax errors where one forget a ' when closing a hard 
coded string value

Very Very thanks kris...
I got 100% score with your dumps...

Conditional block: Specify a variable based on which 
objects inserted into a 
block can be conditionally rendered.
for example user can have option for List report or chart 
report when he runs the report.
Try this out........
CONDITIONAL BLOCKS
The goal of this report is to prompt users on which display 
they would prefer, a list or a chart.
To start, create a simple list report in Report Studio. 
Using the Cognos sample data, product line, order method 
and revenue are added to the list. From the toolbox, drag 
and place a pie chart below the list. Select the chart and 
in the properties pane, attach this chart to query 1:
 
 
 
 
Now the chart can be populated from the data items tab.
 
 
 
 
The consumers of this report need the ability to choose 
between the displays they want to see. To accomplish this, 
build a blank prompt page allowing them to select from a 
drop down list either list or chart. Drag a value prompt to 
the prompt page with the following settings:
 
 
 
At this point hit ‘Finish”. The dropdown list has to be 
populated manually though the static choices property of 
the value prompt. The two choices added are list and chart.
 
 
 
 
 
*You can leave the display value blank. If you do so, 
Report Studio is smart enough that it will take the use 
value for the display value.
Now that my prompt page is set, return to the Report Page. 
In order to conditionally display an object, use the 
conditional blocks object in the toolbox. Drag this to the 
bottom of the report.
 
 
 
 
The next step is to attach the variable to the conditional 
blocks block variable property. This variable is a Boolean 
variable that either equals a list or doesn’t.
 
 
 
 
 
 
 
 
We need to test if our parameter is equal to the 
value ‘List’. If the user selected List this expression 
will evaluate to true, if the user selected ‘Chart’ from 
the prompt, then this will evaluate to false.
After this step is completed there is a new property on the 
conditional blocks object that tell us which block we are 
currently looking at. First, drag the chart into the ‘No’ 
block.
 
 
 
 
 
Now, select the conditional block again, and switch the 
current block property to ‘Yes’. The conditional blocks 
object appears empty because there is currently nothing in 
the ‘Yes’ block.
 
 
 
The final step is to drag the entire list inside the ‘Yes’ 
block.
 
 
 
Now when the report is run, the user will be prompted for 
their display of choice.

Select the regions data item and click on "Set Page Break"
from structure menu.
Run report in Excel you will have different sheets for each
region.
