What Hybris version are you using - x.x.x.x? Can you share the stacktrace / logs of the error?

You can create custom grouping handler, so when you pass data to sapreturnOrder-raw your custom handler will get called

My requirement is not provide new grouping handler which has been already added to sapreturnOrder-raw, but I want to override OTB grouping handler, I have created grouping handler in my custom extension and in my grouping handler I want to override ITB grouping handler . Is there any way I can do that??
