Attributes not visible in Cube when adding with AMO and Hierarchyenabled = false

I need help with a big problem.

I'm using AMO to add new Attributes to a Dimension and I have to use AttributeHierarchyEnabled property = false as Default.

But then I'm never able again to see the Attribute in the Cube though I change with Visiual Studio the property to true.

If use AttributeHierarchyEnabled = true all works fine.

Dimension dim = mDataBase.Dimensions.GetByName(Attr.DimensionName);

DimensionAttribute Attribute = dim.Attributes.FindByName(Attr.AttributeName);

Attribute = new DimensionAttribute();

Attribute.Name = Attr.AttributeName;

Attribute.ID = Attr.AttributeName;

...

Attribute.AttributeHierarchyEnabled = true;

dim.Attributes.Add(Attribute);

Thanks for any help.

You need set the AttributeHierarchyEnabled to true for both DimensionAttribute and CubeAttribute in AMO.

In visual studio, you need change the property both in dimension attribute property dialog and cube attribute dialog.
