In the mapping I am working on the requiorement is like this
If the value for HeaderComment1 exists in the input payloadd,then the first 35 characters of the HeaderComment1 should be mapped to the target field 4440.
But the input can consist of less than 35 characters as well.
So,if I use the Substring function with range as 0 to 35 then an exception occures.
Please help me on this.
Thanks in advance
