Branch Server and Head Office

Good Day,

I would like to ask how can i get this goals on our AX 2012 r2,

We have a Branches and also Head Office,

But i would like the branches to have their own server that connects to Head Office

so that even theirs no connection the branches can still do transaction on AX,

But if the connection restore to normal, The Branch Server will now Sync to

Head Office Server for the data loss.

Is this Possible?

Regards,

EOS
