Restrict Access to Data Mart Fields
You can restrict the field attributes so that only one user or business group is authorized to change them. This requires that your Data Mart field attributes not be used for OLAP reports or other uses.
Limit the Number of Entities per Model Manager
Similar to the number of entities per OLAP process you can also control the number of entities per model manager. You can increase or decrease the default value of 1,000.
Use a Naming Convention to Clarify Mart Usage
You can reduce use of your Data Mart fields for unintended purposes by prepending them with “dm” or a similar convention.
Use Comments to Identify Mart Fields
Each field attribute features a Comments section displayed in the Data Mart field selector. You can display a standard comment during model field selection, leading you to select only designated Mart field attributes.
Usage Indicator in the Mart Field Add Window
A blue dot next to any field in the Add window, linked from the model UI Fields tab, indicates that the field is used in another model. Your field attribute list may contain multiple field attributes with the same description. If so, the blue dot indicates which of those same-named fields you have used elsewhere in the Mart. You can then reselect the blue-dot fields to maintain consistency of business definition across models.
Clarify the Identity of Grouping Fields
You may find it useful to use a naming convention to distinguish the Mart table column names of your grouping fields. This is because when these fields are in a group-level table, your report developers may find it difficult to quickly identify which are the grouping fields and which are regular non-grouping fields. A suggestion is to prepend them with “GRP_” or append them with “_GRP”.
Convert Group Models to Dynamic Performance
Use Dynamic Performance to convert a group-level model from using a performance dictionary to the dynamic performance approach. This requires that the Mart model’s grouping does not use a performance dictionary, and that the dictionary is mapped to the Mart model in the Fields tab. This restriction applies because you cannot change the grouping structure of a group-level model once it is populated with data. Use the Remove link opposite the Performance Dictionary Mapping link to cancel use of the dictionary and use dynamic performance going forward. You can change back to use of the dictionary if necessary.
The most common use case for doing this is if your organization has decided to discontinue running performance calculations for a particular performance dictionary, and use a dynamic approach instead. If you do this, you can also apply this policy to the Data Mart.
