How can I assign a attribute dimension to a Dimension with java-API?

Hello Community,

I need your help with essbase java-API with 11.1.2.4.

I want the attribute dimension "Brand" assign to the dimension "Entity" with Java-API.

For me the expression is missing for the assign for attribute dimension to dimension.

Could you help me?

   outline = cube.openOutline(false, true, false, false);

   IEssDimension dim = null;

   dim = outline.findDimension("Brand");

   dim.setCategory(IEssDimension.EEssDimensionCategory.ATTRIBUTE);

   dim.setAttributeDimensionDataType(IEssDimension.EEssAttributeDataType.TEXT);

   dim.updatePropertyValues();

Thank you very much

Benjamin
