Hi neeraj,
You cannot use if then else explicitly in tMap, however you can use a java ternary expression. e.g. row1.field.equals("TRUE") ? 1 : 0
If you have to use if then else then use a tJavaRow or write a custom routine.

If you trying to print the value of row1.field what does it prints?

I have used it number of times and it has worked everytime.

Hi,
The problem is with data type. now i have changed the data type of that field as "Boolean" and it is working fine.
Thanks.
