Rules regarding members of attribute dimensions and their base dimensions. You can tag only sparse dimensions as attribute dimensions.
Before you can save an outline to the server, each attribute dimension must be associated with a standard, sparse dimension as its base dimension. Attribute dimensions must be the last dimensions in the outline.
Attribute dimensions have a type setting—text, numeric, Boolean, or date. Text is the default setting. Although assigned at the dimension level, the type applies only to the level 0 members of the dimension. If you remove the attribute tag from a dimension, Essbase removes prefixes or suffixes from its member names. Prefixes and suffixes are not visible in the outline. A base dimension member can have many attributes, but only one attribute from each attribute dimension.
For example, product can have size and packaging attributes, but only one size and only one type of packaging. You cannot associate an attribute with an implied shared member, the child of which is tagged as shared. An attribute dimension must be associated with a sparse standard dimension. A standard dimension can be a base dimension for multiple attribute dimensions. An attribute dimension can be associated with only one base dimension. An attribute dimension's base dimension also must be sparse Can be dense or sparse Storage property Can be Dynamic Calc only.
Therefore, not stored in the database. The outline does not display this property. Can be Store Data, Dynamic Calc and Store, Dynamic Calc, Never Share, or Label Only Position in outline Must be the last dimensions in the outline Must be above all attribute dimensions in the outline Partitions Cannot be defined along attribute dimensions, but you can use attributes to define a partition on a base dimension Can be defined along standard dimensions Formulas on members Cannot be associated Can be associated Shared members Not allowed Allowed Two-pass calculation member property Not available Available Two-pass calculation with runtime formula If a member formula contains a runtime- dependent function associated with an attribute member name, and the member with the formula is tagged as two-pass, calculation skips the member and issues a warning message.
Calculation is performed on standard members with runtime formulas and tagged two-pass. Two-pass, multiple dimensions: Calculation order Order of calculation of members tagged two-pass depends on order in outline.
The last dimension is calculated last. Calculation result is not dependent on outline order for members tagged two-pass in multiple dimensions. Two-pass calculation with no member formula Calculation skipped, warning message issued. Therefore, member intersection of two-pass tagged members and upper-level members may return different results from calculation on standard dimensions.
Available Dense Dynamic Calc members in nonexisting stored blocks Calculations skip dense dimensions if they are on nonexisting stored blocks. For attributes to work on dense members, Available 3.
Functionality Attribute Dimensions Standard Dimensions data blocks for the dense members must exist. Richard Chan Posted June 29, 0 Comments. I take it that you are referring to Essbase? Lwazi Ntloko Posted July 4, 0 Comments. No — this was actually referring to attributes defined Oracle for Olap. Register or Login. Welcome back!

The tables in this topic describe the differences between attributes and UDAs in these areas of functionality:. Data storage Table Data retrieval Table Data conversion Table Calculation scripts Table You can group and retrieve consolidated totals by attribute or UDA value.
For example, associate the value High Focus Item to various members of the Product dimension and use that term to retrieve totals and details for only those members.
More difficult to implement, requiring additional calculation scripts or commands. You can categorize attributes in a hierarchy and retrieve consolidated totals by higher levels in the attribute hierarchy; for example, if each product has a size attribute such as 8, 12, 16, or 32, and the sizes are categorized as small, medium, and large. You can view the total sales of small products. You can create crosstab views displaying aggregate totals of attributes associated with the same base dimension.
You can show a crosstab of all values of each attribute dimension. You can retrieve only totals based on specific UDA values. Ans: Objects gets locked to prevent users to make simultaneous and conflicting changes to Essbase database objects. By default whenever an object is accessed through Aministrative services console or Excel spreadsheet add-in, it gets locked. What is the difference between UDA's and Attribute dimensions?
Ans : Attribute dimensions provides more flexibility than UDA's. Attribute calculations dimensions which include five members with the default names sum, count, min, max and avg are automatically created for the attribute dimensions and are calculate dynamically. How does Attribute dimensions and UDA's impact batch calculation performance? Attribute dim- No Impact as they perform only dynamic calculations.
What are different types of attributes? Ans: Essbase supports two different types of attributes. User-Defined attributes 2. Simple attributes User-Defined attributes: The attributes that are defined by the user. Simple attributes: Essbase supports some attributes, they are: Boolean, date, number, and string. What are filters? Ans: A method of controlling access to database cells in essbase. A filter is the most detailed level of security, allowing you to define varying access levels different users can have to individual database values.
Ans: TB First: in the Sample. Opening Inventory consolidates the value of the first month in each quarter and uses that value for that months parent. For example, the value for Qtr1 is the same as the value for Jan.
TB Last: in the Sample. Ending Inventory consolidates the value for the last month in each quarter and uses that value for that months parent. For example, the value for Qtr1 is the same as the value for Mar. How can we display UDA's in reports? How do they impact report report performance. Ans: UDA's values are never displayed in the reports and hence do not impact report performance.
How does Attribute dim impact report performance? Ans: They highly impact the report performance as the attributes are calculated dynamically when referenced in the report.
For very large number of att dim displayed in the report, the performance could drastically reduce.
