Calculation Architecture

Topics

• Types of calculations

• Data storage

• Calculation order

• Dynamic Calculations

• Two-pass calculations

• Intelligent Calcs

Types of Calculation

• Outline calculations

• Calc script calculations

Outline Calculations

Calculations based on member relationships in a dimension

Default Calculation

• The default for the database is CALC ALL.

• A different default calculation can be set using Essbase Application Manager or ESSCMD.

Default Calculation Characteristics

The default calc, CALC ALL• minimizes physical passes through database.

• allows users with access to specific calc scripts to run default calc.

Calc Script Calculations

• Contents of calc scripts: commands, formulas, and functions

• Reasons for calc scripts

• Functions and commands that only work in scripts

Calculation Order

• Data storage

• Dimension types

Dense and Sparse Dimensions

Dynamic Calculations

• Dynamic Calc (Non-Store)

• Dynamic Calc and Store

• Dynamic Time Series

Dynamic Calc Member Settings

• Dense and sparse dimensions

• Dynamic Calc restrictions

• Considerations

Calculation Order: Dynamic Calcs Versus Batch

• Batch• Dimension with

Accounts tag

• Dimension with Time tag

• Dense dimensions in outline order

• Sparse dimension in outline order

• Two-pass calculations

• Dynamic Calc• Sparse dimensions in

outline order

• Time series calculations

• Dimension with Accounts tag

• Dimension with Time tag

• Dense dimensions in outline order

• Two-pass calculations

Dynamic Calculation Limitations

• Members that cannot be dynamic

• Loading data

• Parent/child considerations
