How to reference a column value in a particular block.

Question

I am having problem in referencing a column in a particular Block in WEBi report.
Scenario: I have only one query in the query panel and i am creating a sample report having different blocks.
               Now there are four blocks in my report,
               1st Block: It it a table with two columns [country name], [Turn over]. Now this is converted into pie chart.
               2nd Block: It is the same table as above but it is linked with the block 1 so that whenever i clicked on a particular company name
                               in the pie-chart then this block will be showing only the company name and its turn over for that particular company.
               3rd Block: It is also the same table as above having same columns but it is showing top five company names and their turn over value.
                               I used ranking function through a variable for impelmenting this.
               4th Block: It is a table having columns [Company Code], [Company Name], [Turn over], [Company Address].
Problem:  Now i want to show hide 4th block when the [company name] value in 2nd block lies in the list of top 5 companies in 3rd block or else 4th block
               will show the table having complete info of the particular company which has been clicked in the pie-chart and 2nd block will be showing the
                comapny name and its turn over value.
Please help me with this problem as soon as possible, i am learning WEBi tool and now i am stuck with this use case.

Hello Surabh,
Thank you for providing an example, from the example try the steps from 3rd block to reach your requirement
1st block: Let's say i clicked on country name- ITALY in the pie chart.
2nd block: Now the second block will be showing ITALY in column [country name] and its turnover in [Turn Over] column
3rd block: This block is showing the names of top 5 countries in column [country name]  on the basis of their turnover and their corresponding turnover in column [Turn Over].
Here on 3rd block you have to place  logic for ranking
1. Create a report level variable of type Dimension with name "Ranking"
Ex:
=NoFilter((Rank([Turn Over];[Country name];Top)))
2. Add a block filter as:[Ranking]Less than or equal to 5 , to show top 5 countries
3. Create a new Dimension Variable with name(As you like) "Show" with the below definition
=If([Ranking]>5;1;0)
4. Add the Variable Dimensions created [Ranking], [Show] objects to2nd block
* Right click on [Show] column and choose "Hide" ->"Hide dimension", this will hide [Show] column from the table.
* Select 2nd block right click, select 'Format Table'->Select the check box "Hide when following formula is true" and define a condition as
=([Show]=1)
5. On 4th block add Variable dimension objects created [Ranking], [Show]
* Right click on [Show] column and choose "Hide" ->"Hide dimension", this will hide [Show] column from the table.
* Select 2nd block right click, select 'Format Table'->Select the check box "Hide when following formula is true" and define a condition as
=([Show]=0)
With this when rank of a country greater than 5 then block 3 will be displayed, otherwise block 4 will be displayed.
Hope this answers your requirement
