How to add newly available nodes to an old XBO

Hello,

We have an XBO for Opportunity. It was created in 2014. SAP has enabled other nodes in Opportunity for extension later to that, for eg SalesForecast.

How do we include this extension to our XBO so that we can use error messages etc.

When I tried to manually insert, it created two nodes with the same name and created a lot of mess.

Anyone ran into this and fixed it?

thanks
