Hi,

No need of udf.

If there is no value no node will be created.

Map it like this

Node--

---

<b>Exists</b>--

---

<b>IF</b> node function -

---

target node.

map the node to the <b>THEN</b> brancH and the constant value to the <b>Else</b> branch of IF condition.

Hi

Do not use exist to check this logic if you are providing the source structure with blank value in the structure. Exists only checks if a particular node is present or not..

If you have to map corresponding to blank value in source, then refer to the 2nd solution i.e: compare ur source with space using the text equals function and then process with the if else logic

Phani,

Do the mapping like below

Test->MapwithDefault->Test

I'm sure it will work.

Best regards,

raj.

This was the test results,

1. When there is an input for the Name node

2. When there is no input for the name node the output was filled with the value specified in the constant. Inmy case it was empty.

I was not able to see the mapping in the link that u provided...

Hi Santosh,

Can U Explain How this IF Then Else Function will Work here

Regards

Phani

[santhosh_kumarv · Accepted solution]

Hi Phani,

Here the IF conditions Checks

<b>IF</b> the node is equal to Empty

if true the node mapped to the <b>THEN</b> will be mapped to the target

if false i.e the node = ' ' then the node mapped to <b>ELSE</b> will be mapped to the target node.

Hi,

You can simply use the IF -> EXISTS->THEN->ELSE->MAP WITH DEFAULT function

Kumar.

P.S: Reward points if helpful!!!!

Hi Phani,

You can proceed without writing UDF by using the standard functions which are available ie You can check for the existance of the node and value.If it doesnt exists then they u can use mapwithdefault function which is there in the standard functions to map the default value to the target side.

Prasanthi.

Are u sure u want a UDF. This can be done using standard functions also. Functions Such as if, constant etc.

Hi phani,

You don't need UDF for it...

You can either check whether the source tag exists using exists function under node functions and then implement an if else logic to pass either the original source tag or a constant value...

Else if you want mapping to occur when input is space, you can do a text equals and again implement an if else logic

Thanks
