Field optional in Content Conversion

Question

Hi,
This is my data structure
Field1
Field2
Field3.
I have two source systems which is sending the data.
One of the source system sends only Field1 and Field 3, while another source system sends Field1,Field2 and Field3.
Should i make the field2 as optional and handle it in content conversion , or would i require separate mapping.
If this needs to be handled in CC, let me know how.

Hi Daniele,
Instead of using the standard funciton , i created a UDF for handling this situation.
My logic is UDF is like
   //write your code here
int Size = Integer.parseInt(Truncate_Size);
String Return_Value = "";
     if  (!("".equals(Input)) )
          if  (Input.length() > Size )
               Return_Value = Input.substring(0,Size);
          else
               Return_Value = Input.substring(0, Input.length());
     else
          for(int i = 0; i< Size ; i++)
          Return_Value = Return_Value + " " ;
return Return_Value;
SO in this case also , it should be able to handle empy source element. But it is not working.
