Essbase Calculation Scripts: Structure and Syntax

Calculation scripts are integral to Essbase's analytical capabilities, enabling complex calculations across multidimensional data.

Basic Structure of a Calculation Script

A typical calculation script consists of:

• Commands: Define operations like `FIX`, `CALC`, `WHERE`, etc.
• Blocks: Segments of commands grouped together.
• Variables: Used for dynamic referencing.

Common Calculation Script Commands

| Command | Description | Example |

|---|---|---|

| `FIX` | Defines a set of members to operate on | `FIX (Product, Year)` |

| `CALC` | Performs calculations on the fixed members | `CALC DIM` |

| `ENDFIX` | Ends the FIX block | `ENDFIX` |

| `IF` | Conditional logic | `IF (Sales > 10000)` |

| `ELSE` | Alternative logic | `ELSE` |

| `ENDIF` | Ends if statement | `ENDIF` |

Sample Calculation Script

```plaintext

FIX (Product, Year)

SALES = SALES 1.10;

ENDFIX

```

This script increases sales figures by 10% for each product and year.

Data Load and Export Scripts

Efficient data movement hinges on well-crafted load and export scripts.

Data Load Script Elements

• Data Source Specification: Define where data comes from.
• Mapping: Map source data columns to database members.
• Error Handling: Manage load errors.

Sample Data Load Script

```plaintext

LOAD DATA

FROM 'sales_data.txt'

MISSING VALUE ''

APPEND

DIMENSION VALUES (Region, Product, Year)

```

Data Export Script Example

```plaintext

EXPORT DATA

FROM DATABASE 'SalesApp'

TO 'exported_sales.txt'

DIMENSION VALUES (Region, Product, Year)

```

MaxL Scripts for Database Administration

MaxL scripts provide powerful commands for managing Essbase environments, such as creating, deploying, and securing databases.

Example MaxL Script for Creating a Database

```sql

create database SalesDB

user 'admin' identified by 'password'

on 'C:\Essbase\Apps\SalesApp'

using outline 'C:\Essbase\Outline\SalesOutline.otn'

```
