Mapping problem

[Former Member]

Hi guys,

I'm trying to satisfy following mapping condition but I can't achieve it:

if NodaA(1..1) exists, repeat per each NodeX, else repeat it per each NodeY.

The problem is EXISTS function returns only one item in the queue and NodeX and NodeY have different number of occurence. If these would be the same I could use OneAsMany, byt if NodeX is there 5times and NodeY 7, I'm not able to do it.

Any ideas, how to acjieve this?

Thanks a lot,

Peter

Hi Peter,

You can do this using a ADVANCED UDF. Try this.

The UDF will have three inputs:

1. NodeX>Remove Context>

2. NodeY>Remove Context>UDF

3. NodeA> Exist>

The UDF Cache Value will be queue.

Public Sample(String[] NodeX,String[] NodeY,String[] NodeA Container.....) {

if(NodeA[0].equals("true"))

{

for (int i=0;i<NodeX.length;i++)

result.addValue(NodeX<i>);

}

else

{

for (int j=0;j<NodeX.length;j++)

result.addValue(NodeY[j]);

}

}// end of class

DSP boys, sorry, my mistake - the occurence is 0..1.

Bhargav, this is what I needed. I tried so hard to work with standard functions that I forgot this option

Thanks,

Peter

Hi Peter,

There is no need to check if NodaA exists because its occurence is already 1..1 (Mandatory). I hope this helps...

Hi!

Have you tried to change the context of NodaA?
