Tip Name: Creating Read-Only Computed Items

Purpose / Use: To provide users with standard computed items that they can use but

not modify. This insures that all users have common computational

definitions.

Sample File: Read-only computed items.bqy

Steps to Produce: To create read-only computations, you will build one or more computed

items pre-defined in the query’s data model, and then promote the

query’s data model to a read-only locked Master Data Model.

1) Build a regular data model as you normally would.

2) Right-click on each topic in the title bar and promote it to be a meta-topic. (Computed

items in a data model can only be added to a meta-topic.)

3) Rename each meta-topic (if desired) by double-clicking on the meta-topic’s title bar and

changing the Topic Name property.

4) Select the meta-topic to which you want to add the computed items, then use the

DataModel | Add Meta Topic Item menu selection to define the new computed item(s).
