Problem with the syntax in UDF

[former_member662815]

Hello SAP PI gurus

I am not a java programmer and am trying to play with it.

I want 2 integers or decimal values to be sent to UDF and in return the UDF should send the sum of those two values.

Please see the attachment for the UDF details.

When I try to activate it fails with the following error

Why don't you use the standard Arithmetic "subtract" function for this?

If you want to use UDF, then change the input value type form Int to Float as you may have decimal values and use the below code.

return Float.toString(var1-var2);

Thanks Hareesh

I am trying to understand using UDF since I have to use it soon.

You are trying to return an integer value and hence you are getting that error.

Just change the return statement to Integer.toString(DiscountedPrice);

but this may not handle the decimal values.
