Transformation in a Process Flow

Question

Hi there,
I am trying to use a transformation in a process flow and I am getting the following error -
RPE-02040: Internal error: SOMEFUNC cannot be converted to a constant value. Please correct the value.
I have a PL/SQL function SOMEFUNC(x, y) that takes two values and returns a varchar2(10). I imported this function as a transformation with the same name. The mapping after this takes a varchar2(10) as input.
As soon as I bind the input parameter of the mapping following this transformation, I get the above error. If I don't bind it, then there are no errors but that is not useful to me. I need to pass in the return value of this function to the mapping that follows it.
Has anyone been able to do this successfully? How did you get it to work?
This is OWB 10.2.0.2.
Thanks

Thanks for that link David,
that does explain some things but unfortunately I am still running into the same problem.
So here is what I have -
Start -> Transformation -> Assign -> Mapping -> End_Success
I could not see any way to add a variable in OWB 10.2.0.2.8. You could do this earlier from the Start operator but there is no such option in this version. The Assign operator seems to be designed for this.
I bound the mapping for Assign input value to Transformation's out bound value. And I bound Mapping's input parameter to Assign's output variable. I then validated and generated this process flow successfully. However while deploying, I still got -
RPE-02040: Internal error: Transformation cannot be converted to a constant value.
My OWB client version is 10.2.0.2.8 and repository's version is 10.2.0.2.0. Have you run into this problem before?
Thanks
