Hi,

You can achieve this using a UDF or with Std Graphical mapping (if there are no further complex checks involved)

1. An alternative approach would be as follows. This UDF will not give you errors when length is Less than 9, nor it will fail if the Source node is absent/ empty

str = str1.substring(0, Math.min(9, str1.length()));

2. You can achieve this using std Graphical mapping as well as follows:

you need to change your udf like below

if(str1.length() > 10) then use str1.substring(0,9) else str1.

Hi Mrityunjoy,

                   This error will only result. if the length of the input string (str1) string is less than 10 characters.

Hi,

Is your str1 greater than or equal to 10 characters? Please check all the values in the context.

If not you will get this error.
