FREE - OneStream Event Handlers: Automate, Validate and Control Platform Processes (3 hours)
YOU MUST BE A ONESTREAM CUSTOMER OR PARTNER
If you want to move beyond configuring OneStream and start to develop and extend the OneStream platform, this session is ideal for you.
Event Handlers allow OneStream to respond automatically to activity across the platform. They can be used to automate tasks, introduce additional controls, improve the user experience, and connect business processes with custom logic. In this free, instructor-led training session, you will gain a practical introduction to OneStream Event Handlers and understand how they fit within the wider Business Rule framework.
Using VB.NET and the OneStream APIs, you will create and test an Event Handler, explore the information OneStream passes to your rule, and see how business rules can be used to respond to different events.
You will work with concepts such as before and after events, OperationName, event arguments and contextual inputs, gaining practical experience of how Event Handlers operate within a OneStream application.
- Duration: 3 hours (3 CPE credits) - FREE OF CHARGE
- Audience: OneStream System Administrators, Implementation Consultants, Solution Architects
Learning Objectives:
- Recall how Event Handlers work and where they can be used
- Explain how OneStream passes event information into Business Rules

- Recall how logging and debugging techniques can be used to test and troubleshoot code
Who Should Attend?
This session is ideal for OneStream System Administrators, Consultants, Implementation Partners, Solution Architects, technical application owners and experienced users looking to develop their Business Rule and scripting skills. You should already be comfortable navigating a OneStream application, and while a basic understanding of scripting concepts would be helpful, previous experience with VB.NET is not required.
Take Your OneStream Skills Further:
Event Handlers provide an excellent introduction to the wider possibilities of OneStream scripting and Business Rules. The session also introduces concepts explored in greater depth in the Keyteach OneStream: Platform Rules and Financial Calculations course, including Business Rules, APIs, reusable scripting techniques and financial calculation logic.
Please note: This session is exclusively available to OneStream customers and partners.
