Hi Midhun,

If you create the UDF directly in Definition tab if this UDF is not reflected under functions tab you will get this error.

Try to create the UDF directly under functions tab.

You can simply use standard replacestring text function for that right?

However it's not a problem with UDF code, check below thread (Anoop Garg) to fix

Hi Praveen

It's working fine, now. I created under Functions tab. I am getting output as expected..

However,

public void RemoveCommas(String[] var1, Container container) throws StreamTransformationException{

I am not able to edit the var1 there. I think i have to use the same var1 whenever i create udfs

wonder whether it will throw error if i create more than two udfs in same mapping. Each udf will have same var1 for string entered

We have lots of udf requirements. I was trying something simple to get the feel of single stack

>>>wonder whether it will throw error if i create more than two udfs in same mapping. Each udf will have same var1 for string entere

var1 i local to that udf. You can use the var1 as many times as you want in a mapping

but this can be anything. you should be able to change this under arguments section.

>>>We have lots of udf requirements. I was trying something simple to get the feel of single stack

UDF's remains same in single/dual stack

Hi Midhun,

You can change variable name under Signature Variables section.
