[OBIEE 10g] Data Level Security

 

Data Level Security

   
     Data Level security is implemented in the case when the user logging in views the data which he / she has the access to. This includes to include a system session variable 'USER'to capture the user's logging credentials and apply it to the reports query.

  I am having three tables for serving their purpose.
 
1. Dimension Table - DIM2
2. Fact Table  - FACT1
3. Security Table -SECURITY_1

Data present in the above tables is shown below-

Next we need to import the three tables in the RPD and do the below joins-

Joins with Dimension and Security table in physical Layer


"DIM2"."COUNTRYID" = "SECURITY_1"."COUNTRYID"

Joins with Fact and Security table in physical Layer

"FACT1"."EMPID" = "SECURITY_1"."EMPID"

Joins with Fact and Security table in physical Layer

"DIM2"."COUNTRYID" ="FACT1"."COUNTRY_ID"


In the BMM layer for the dimension table we need to make the below changes. This change is used to apply when the user selects only the dimension column. So that the values which he/ she has the access will be shown after making the joins with the security table. For example- On clicking of the Prompt values.

And the below change in the Content Tab -where clause

In the BMM layer for the fact table we need to make the below changes. Data will be restricted after making joins with the security table and joins with the dimension  table. You can try removing the joins with the dimension and security tables which is not mandatory, since we are joining with the fact and security tables.

And the below change in the Content Tab -where clause

Now its time to view our reports in answers. When the user logs in with 100 as empid then the user is allowed to view only his/ her data.

With the Fact column-

  

When the user with 200 empid logs in-

Prompt value shown for the user with empid 200

With Fact Dimension columns with Security tables joins. With user with login id as 100
