I cannot modify Dimensions properly. Why?
This problem can occur if 'Orderbydes' column and 'Level' column are defined in different DB columns. For any Dimension defined in the data model, both the 'Orderbydes' column and the 'Level' Column should be defined with the same DB column. We cannot provide a different column name in 'Orderbydes' because it will not support multi parse queries and expression measures (if any). This is an advanced configuration, please consult Support team before making changes.
