TM1 attribute cube rule

If you create any dimension attributes, TM1 will create “}ElementSecurity_” cube to store the attribute values. You can use it cube almost like a regular cube (there are just little restrictions).
For example you can create a rule to calculate some attributes. This approach can be used to allow users to edit element attributes in some cube and use “}ElementSecurity_” cube rule to retrieve the values.
Just keep in mind, TM1 does not support a rule on a numeric element in an attribute cube. This is done to support numeric attribute values for consolidated elements. You still can write the rules using the text representation of a valid number. Otherwise TM1 will ignore “N:” statements and you may think that TM1 attribute cube rule does not work.
