Hi Dinesh,

Is the length of the string is constant? If so then you can go ahead with the mapping as said. If the length varies then you need to write a UDF for it.

Hi Dinesh,

If the length of the input varies, then you need to write a UDF to fulfill your requirement.

Try with the below code:

a[0]= "c" + a[0].substring(4,a[0].length());
result.addValue(a[0]);

Hi,

This simple UDF will do what you want:

The UDF takes a single String array as input, say s[ ] and it has a single ResultList item result as output.

The complete code is as follows:

 s[0]="sw"+s[0].substring(4,s[0].length());
 result.addValue(s[0]);

Pass the output of the UDF to the required target field. That's it.

HOPE IT HELPS YOU BUDDY!!!

THANKS

U can do it with graphical mapping itself

u can use substring function and remove the first four character then use concat function along with constant to append the sw value.
