If you use the UPDATE script commands to modify application, dimension, or member property values, you must use the Property Name and not the Property Label displayed in the Performance Management Architect Property Grid. Property labels and names are documented in the appendixes of the Oracle Hyperion Enterprise Performance Management Architect Administrator's Guide. The following script shows an example:
Update Member
Properties(DimensionName, ParentName, MemberName, AggregationWeight, NumDecimalPlaces)
Values('ScenarioDim', '#root', 'Member1', '3', '2');
In this example DimensionName, ParentName and MemberName are all standard script items, however, AggregationWeight and NumDecimalPlaces are Oracle Hyperion EPM Architect member level properties.
