Issue in Comparing two strings using report level variable

building reports webintelligence legacy
1

Hi All ,

I have a scenario where in i need to compare data of two columns. Both columns are Strings.
below are the scenarios to be covered

Scenario 1 : if column 1 has a value and Column 2 is NULL = its a Mismatch
Scenario2 : if column 1 is NULL and Column 2 has a Value = its a Mismatch
Scenario 3 : if column 1 has a value and its found in Coulmn 2 (any position in set of strings) =Not a Mismatch
Scenario4 : if column 1 value matches with Column 2 value= its not a Mismatch
Scenario 5: If both columns are NULL = its not a mismatch

please refer the attachment

Note : I have tried to achieve the above scnerios by creating a report level variable and have defined as below

if (IsNull([column1)) then “Y”
else
If(Match([column1];“[column2]”);“Y”;“N”)

The above logic holds good for scenario 2,3,5 but do not cover the rest

I use SAP BusinessObjects BI Platform 4.1 Support Pack 6 Patch 4
Version: 14.1.6.1848

Can anyone please assist

Thanks,
