Overview of this book

Oracle Essbase is a Multi-Dimensional Online Analytical Processing (OLAP) server, providing a rich environment for effectively developing custom analytic and enterprise performance management applications. Oracle Essbase enables business users to quickly model complex business scenarios. This practical cookbook shows you the advanced development techniques when building Essbase Applications and how to take these applications further. Packed with over 90 task-based and immediately reusable recipes, this book starts by showing you how to use a relational data model to build and load an Essbase cube and how to create a data source, prepare the mini schema, and work with the data elements in Essbase Studio. The book then dives into topics such as building the BSO cube, building the ASO cube, using EAS for development, creating Calculation Scripts and using MaxL to automate processes.

Adding the solve order column to tables that have ASO formulas

In this recipe, we will include an additional column to our MEASURES table to specify the solve order for the hierarchy. The ASO outline does not have the Two Pass Calc option in its Account dimension; as a result, you will have to specify the solve order by adding an additional column.

Getting ready

To get started, open SQL Server Management Studio, and add a database called TBC . In this recipe, we are using T-SQL, but the PL\SQL equivalent is provided in the examples. The MEASURES dimension was created in the recipe Setting up an Account or Measure dimension with parent-child reference in Chapter 1. We need to complete step 1 of the aforementioned recipe before we continue.

How to do it...

Execute the following script to add the FORMULA_MDX and SOLVE_ORDER columns to the MEASURES table, if it does not exist:

--This is the script in T-SQL
Alter Table MEASURES Add FORMULA_MDX VARCHAR(4000) NULL;
Alter Table MEASURES Add SOLVE_ORDER INT NULL;
--This is the script in PL-SQL
Alter Table MEASURES ADD FORMULA_MDX VARCHAR2(4000) NULL;
Alter Table MEASURES Add SOLVE_ORDER INTEGER NULL;

Execute the following scripts to add the formula and the solve order values to the MEASURES table:

INSERT INTO MEASURES
  (SORTKEY,MEASURESID,PARENT,CHILD,MEASURES_ALIAS,CONSOLIDATION,TWOP ASSCALC,STORAGE,VARIANCEREPORTING,TIMEBALANCE,SKIP,UDA,FORMULA,COMMENT_ESSBASE,FORMULA_MDX, SOLVE_ORDER) Values(0, 14, 'Ratios', 'Margin %', '', '+', 'T','X', '', '', '', '', 'Margin % Sales;', '', '[Measures].[Sales] / [Measures].[Margin];', 20);

INSERT INTO MEASURES(SORTKEY,MEASURESID,PARENT,CHILD,MEASURES_ALIAS,CONSOLIDATION,TWOPASSCALC,STORAGE,VARIANCEREPORTING,TIMEBALANCE,SKIP,UDA,FORMULA, COMMENT_ESSBASE, FORMULA_MDX, SOLVE_ORDER) Values(0, 15, 'Ratios', 'Profit %', '', '~', 'T', 'X', '', '', '', '', 'Profit % Sales;', '', '[Measures].[Sales] / [Measures].[Profit];', 20);

Select from the table to see the values that you added:
```
Select * From MEASURES;
```

How it works...

We started this recipe by adding the SOLVE_ORDER column to the MEASURES table. We also added two new rows with the SOLVE_ORDER populated. The objective of this recipe is to show you that the SOLVE_ORDER value has to be higher than its respective components in order for the formula to return the correct values. We should consider the following steps when assigning SOLVE_ORDER:

Set up in SOLVE_ORDER in increments of tens or twenties for clarity and consistency.
When the default is not specified, SOLVE_ORDER is zero, but it is good practice to always specify the SOLVE_ORDER to remove ambiguity and define the calculation's priority.
