With the new Computed Attributes feature you can use to create buckets defined by metric ranges. Use computed attributes when you have logical thresholds that you want to group an attribute by. When you include a computed attribute in a report, its buckets appear in that report.
Computed attributes are dynamic. When you change the definition of a metric that a computed attribute is computed from, the buckets are recalculated according to the new metric (for example, if you are ranking sales representatives by quarterly revenue, then change the metric to rank them by monthly revenue). When you upload new data, that data is grouped into the buckets in the computed attribute.
Computed attributes appear in the Attributes menu, and you can use and manage them like other attributes.
When you create a computed attribute, a data set for that computed attribute is also created. To delete a computed attribute you must delete its data set under Manage > Data Sets > [dataset name]. Deleting the data set also deletes its associated computed attribute.
- Computed attributes do not appear and cannot be managed in CloudConnect data models.
- You cannot transfer computed attributes to other projects. (Computed attributes can not be migrated).
- For the Beta release, you cannot change bucket ranges. This capability will be added in the general release.
Example: You set up these buckets for a computed attribute and name it Computed colors:
Log in to the GoodData Portal and go to Manage > Attributes, click Create Computed Attribute.
Follow the steps on Computed Attribute screen. In the Set up buckets step, define your buckets and their threshold values.
Name the attribute and click Create Computed Attribute.
The attribute is created and the Attribute Details page appears. You can manage this computed attribute like other attributes, including adding it to reports.
