Creating a UDF in SAP XI

Question

Hi,
I have Idoc to File Mapping in SAP XI, where I need to populate "Spaces" in most of the Target fields Dynamically. I need to create a UDF for this mapping. Since I have n no.of Target fields where I need to populate Sapces and Target fileds has different lengths. As of now I have cretated a simple UDF which is usefull only for one field mapping. Below is the UDF:
String s;
     char []c = new char[10];
     for(int i=0; i<10; i++)
        c<i> = 'S';
     s = new String(c);
     return s;
2. My source file will be having 1000 records where 999 records will be mapped to Traget sturucture and the end of the Record should be mapped to the other Traget structure(Traget sturcture is same in the both the cases).
Please let me know how can I go about on this.
Thanks in Advance.
Jose

Hi Joseph,
Give a try to use the below UDF for the fields where you want to have some hardcoded values :
a : Field you would like to change
b : New hardcoded value for the field.
for( int i=0; i<a.length; i++)
  if (i==(a.length-1))
      result.addValue(b[0]);
  else
     result.addValue(a<i>);
input_field_1   --------------------
                                       UDF  -------------------- target_field_1
new_constant_EOD  ------------------
Rest all mappings should remain as it is.
Let me know if you face any issue.
Thanks,
