If else possibility in universe designer

Hello

I am trying to implement If else logic in universe designer, but unfortunately I ended up getting error.

Below is my formula

If IsNull(@Select(abc\col1))

then 0

else @Select(abc\col1)

I am getting error From keyword not found where expected.

I am wondering whether if else logic possible in universe designer or it should only be implemeted in WEBI.

Thanks for your help.

Regards

Siva
