Please help me to create and how to use the user defined DataStage functions on basses input columns and implementation if and else conditions .
My next step to map the out put to specified columns.
share your thoughts .
Thanks,

Your first step must be to specify:
(a) what the function does (its algorithm)
(b) what the function's input arguments are
(c) what the result of the function should be (only one value is permitted)
(d) how you plan to test the function
Once you have all that documented, you code the function in C++, compile, link and test it.
If all that's OK, you add an entry into your DataStage project that describes the "parallel routine" - its location and its arguments and their data types. This is information allows the function to be found when programming the Transformer stage and allows the arguments to be checked when validation occurs.
