New Financial dimension related to a table

Hi guys,

In 2012 I've created a new financial dimension link to a custom table with this technique :

https://community.dynamics.com/ax/b/behindax/archive/2015/09/07/ax-2012-create-a-new-financial-dimension-which-related-a-table-s

It Worked well.

Now in Ax 7, it doesn't work.  Looks like there's something missing to helpAx 7 see my new financial dimension.  I've looked at view DimAttributeBankAccountTable and they added a method like this : 

[SubscribesTo(classstr(DimensionEnabledType), delegatestr(DimensionEnabledType, registerDimensionEnabledTypeIdentifiersDelegate))]
public static void registerDimensionEnabledTypeIdentifier(DimensionIEnabledType _dimensionEnabledType)
{
       _dimensionEnabledType.registerViewIdentifier(tablestr(DimAttributeBankAccountTable));
}

I've done the same with my view but still I cannot see that as a financial dimension.

Do you have ideas about what more I need to do?
