Report Level Filter through Variable

Hi Team,

Sample report looks like this.

I have the data points.

1. Sales Person(Name)

2. Lease(Car Leased)

3. Sales(Car Sold)

1. Lease Condition.

Select lease  from table1, table2 where table1.lease='ABC' and table2. columns1 in('N')

2. Sales condition:

Select lease  from table1, table2 where table1.lease='ABC' and table2. columns1 not in('N','L')

I have columns in the report like this now. Please suggest me how to apply condition in the report.
