Transformation Event Handler Sample code

Hi, my advice would be to give it a go yourself and then if you have any specific issues with the code you create then ask for help with that rather than just asking somebody else to produce the code for you. This is the best way you will learn some more advanced techniques on the OneStream platform.

Also the responses to your original question

provided an alternative solution for doing this purely with transformation rules and no scripting. Therefore if you are not up for the scripting challenge you can follow that approach. Yes, it will probably require more initial setup and ongoing maintenance but it also more accessible to your general end user.
