Req for UDF

[Former Member]

Hi All,

In Mapping I have to check for a field, ie if the field has value i need to pass it to target or else need to throw error.

mapping is X (1) ---> Y (0..1) , X is coming from CSV file , if i give blank in the file its processign , but it should throw error.

Do i need to write UDF or can i do it using graphical mapping..

Thanks ,

Monish.

use this UDF

if(a.equals(""))
throw new RuntimeException("Empty input");
else return a;

use mapping

Sourcefield---.UDF--->TargetField

use the mapping as given below

sourceField---.equalS---->not---->createIf----->targetField
  constant[]/

do not give any value in the contant function

With above mapping it's not throwing any error if the source filed is blank , which is not the requirement , it should throw some mapping error stating that source field is empty

Hi,

Why you are not trying with alerts?

You can write UDF to check for field if, field is blank throw some exception.

You can raise alert if any error occurs ,and it can be reiceved at your RWB mail box as well.

For alerts , refer folowing discussion:

HI,

Can you change the occurance of target field as 1..1. and keep the same mapping. In that case it will through an runtime error when source field is space.

HI,

Yes you need to write a UDF. In this UDF check the value to X field. If it is space then through an error else return the value.

Hi,

Here i need to throw error in mapping itself if the value is blank .

hi,

then you should not do it in the mapping but in the receiver determination

try adding a condition in the receiver determination that will check that field

and if it's not there the message will go into an error
