Dear Expert and User

After I create a Sub CFC then call it in some place. then i need to update to that sub CFC.

I would like to know how we can make Sub CFC auto update to all called.

Thank you.

Hello ND120685,

Chart in Chart CFCs can be updated by Drag&Dropping the newer CFC chart on top of the old one. 
There is however no auto-update of Chart in Chart based CFCs. 

The thing you are looking for are Control Module Types. These can be updated automatically in your multiproject. 

Additonally you can also create Variants of these CMTs to adapt your Charts for different use cases. 

In combination with the APL library they are also future-proof.

Best regards 

Stephan
