I want to use customer exit performCustExitBeforeR3Call of CreateStrategyR3.
I have created an extension for class CreateStrategyR3 and implemented the method performCustExitBeforeR3Call.
According to the dev and ext guide all that then needs to be done is add this object to backendobject-config.xml.
I cannot find the right syntax for this however.
Can anyone provide me the right syntax. And is this indeed all, or am I missing anything else.
Thanks in advance.
