How and where to write conditional statement in qlikview

[trishita]

I have two fields .

Deviation after sounding and Difference vs Log survey:

I want to write a code that if the  difference between them is less than 2 then a new column will display yes against the value or else no.

if (Deviation after sounding) - (Difference vs Log survey) <=2 then (NEW COLUMN ) = "Correction done"

or else "Correction Not Done"

You can wirte this in the expression if you want to do it in the front end:

if(([Deviation after sounding] - [Difference vs Log survey]) <=2,'Correction Done','Correction Not Done')
