As the name suggests it defines the scope of analyzing the data when you are drilling  the report.

So let’s see what exactly it is.

Let’s say I have a hierarchy in universe Year–>Quarter–>Month–>Week.

So it means, in the report when I am drilling at these levels it will go through the above hierarchy.

What this feature “Scope of Analysis “actually does?

This is an option in web intelligence query panel.

It allows setting the scope at query time.

For eg. If I selected Year and Revenue in my query and the sql generated here is:

Which is correct.

I ran the report and the results are:

Now I will enable drill option and will try to drill through the hierarchy.

From Year–>Quarter

See the results below.

Webi brought quarter column in the query.

Same way as you drill down to month and week, it will bring in run time other columns as needed by the drill(it will hit the database to bring the columns data)

Now I will use Scope of analysis and see how it behaves.

Note: Scope of analysis by default is set to none.

I will enable scope of analysis and from drop down I will select “One level”.

You will notice that it brought Quarter object in scope of analysis and in query, quarter column which is one level after Year but there is no change in result objects pane, there it is still year and revenue.

I will run the report:

Note: Even though we have not selected Quarter in the select, it is there in query and in left pane (data pane).

This means by selecting scope of analysis , we have brought the quarter also, when we ran the query for  year and revenue.

Even if we drill to quarter from Year now, we don’t have to hit the database to bring quarter results.

But now if I try to drill further to Month from quarter, query will hit the database to bring month data.

Basically this helps in avoiding database hit each time you are drilling for analysis.

If you already set scope of analysis to Custom, it will bring all the objects in the query for that hierarchy and at time of drilling it won’t hit the database to fetch detail data, as it is already in webi microcube. But then you have to decide whether you want detail data to be fetched always when the query runs or bring the data at run time when a reporter is drilling into the levels.

Summary is:

Setting scope of analysis brings objects in the query for the levels you have specified and it wont hit the database while drilling for those levels.

So if you are aware of the users request of a drill you can set this option in the report you have created, so it should not have a time lag at time of drilling.

There is a Web Intelligence security rights for scope of analysis.

  1. This is in CMC–> Application–>WebIntelligence

“Extend Scope of Analysis”

What is this and how it works?

Lets see an example:

I am a report designer and create a report with Year and Revenue and I set the “Scope of Analysis” to 1 level.

As such when I run this report , I can drill from Year–>Quarter and can also drill to other levels(like month, week)  but than for other levels it will hit the database.

Let’s say I have a user ‘X’, I gave this report to him with “Scope of analysis” set to one level.

Assume he has the right to extend scope of analysis, he will be able to access the report same as I did, i.e. can drill to all levels.

But now, if I go to CMC and deny the right “extend scope of analysis”.

This will restrict the user to drill only till quarter only and no further levels , as you have set in your report.

So by this you are actually allowing user to access only the levels you want him to drill down.
