Loading Dates as Data

Purpose

This tutorial shows you how to load dates as data to an Essbase ASO cube.

Time to Complete

Approximately 20 minutes

Overview

After enabling an Essbase outline to accept date measures, you can add them to the measures dimension and usethem for analysis.

Scenario

The Hyptek corporation, manufacturer of hard disk drives, uses Essbase for sales budgeting and forecasting (BSOdatabases), as well as current year and historical sales analysis (ASO databases). Current year "units sold" data isloaded into an Aggregate storage (ASO) cube every month and used for standard and ad hoc reporting. Monthly datafiles are archived at the end of each year.

An interesting challenge has just come across your desk. Hyptek management would like you to create a cumulative-units-to-date report for all of the Roadranger products sold in North American retail channels under New LineIntroduction promotions. The report should be designed to show units sold for each product in the Roadranger linesince the product introduction date. The oldest product was introduced in 2003.

Because data spans such a large period of time, no single cube contains all of the data required, nor does any onlinerelational database. You decide to build a one-off ASO cube to aggregate data from the data load files used for monthly reporting, which are available from machine-readable archives. You will load these into the ASO cube usingan aggregated load.

Since the granularity of time for this project (spanning years) is so different from that of normal reporting (spanning asingle month), you will create a date measure in the Essbase database to store the introduction date for each of theRoadranger products.

The final report should look something like the following figure:

Software and Hardware Requirements

The following is a list of software requirements:

Oracle Essbase 11.1.2

Note: The HyptekAS database used in this OBE was developed for classroom use and is not available as a sampleapplication. However, screenshots are provided for the outline sections used in this OBE.

Prerequisites

None

Creating an Application

To minimize design time, you make a copy of the HyptekAS application (already cleared of data), naming thecopy HyptekRR .

1. In the Navigation panel, right-click the HyptekAS application and select Copy .

2. For the application name, enter HyptekRR .

3. Click OK .

The HyptekRR application is displayed in the Navigation panel.

4. Expand the HyptekRR application and database, then right-click Outline and select Edit .

5. The outline is displayed.

Keep Outline Editor open for the next topic.

Enabling Date Measures

Both text and date measures are typed measures , measures that can be associated with text and date valuesrespectively. Both are enabled in the outline properties, accessed through Outline Editor.

1. Select the Properties tab.

2. In the Properties tab, in the Typed Measures enabled drop-down list, select true .

A confirmation message is displayed, indicating that once you enable an outline to support typed measures, it cannotbe reverted to an outline that does not support typed measures.

3. Click OK .

4. In the Date format drop-down list, select mm-dd-yy .

7/29/2019 Loading Dates as Data

All date measures in the outline will use this date format.

5. Click Verify .

A confirmation message is displayed.

6. Click OK , then click Save . Keep Outline Editor open for the next topic.

Adding a Date Measure to the Outline

In ASO cubes, date measures must be level 0 members of the measures dimension.

1. Select the Outline tab.

2. Expand the Measures dimension, then right-click Measures and select Add child .

A text box is displayed.

3. In the text box, enter Intro Date , and then press Enter .

Another text box is displayed.4. Press Enter again to close the text editor.

Date measure Intro Date is displayed in the outline.5. Right-click Intro Date and select Edit member properties .

Member properties for Intro Date are displayed.6. In the Type drop-down list, select Date .

7. Click OK . Since date measures should not be aggregated, Intro Date is assigned the non-aggregation operator (^) bydefault.

Completing the Outline Changes and Reviewing the Input File

Due to the long time horizon for this analysis, outline members usually associated with monthly reporting areinappropriate. For example, the Fiscal Year dimension normally spans three years--insufficient for this project. Somenew level 0 members need to be added to the outline. (The remaining dimensions already contain members tosupport the cumulative units report.)

1. Add the following level 0 members to the HyptekRR outline:

For Period: Period Unspecified For Fiscal Year: FY Unspecified For Customer: Retail Unspecified

8/19

For Sales Person: Retail Rep Unspecified (not shown in figure)

2. The tab-delimited input file, IntrDate.txt , contains all of the introduction dates for the Roadranger products, as shownin the following figure:

Creating a Rules File for Loading Dates

A data load rule (aka rules file) can be used to load dates as data.

1. Expand database HyptekRR , right-click Rules Files and select Create rules file .

Data Prep Editor is displayed.2. Select File , then Open data file , then navigate to IntrDate.txt and open it.

4. Select View , then Data load fields .

Data load fields are displayed.5. Select Options , then Data source properties .

6. In the Delimiter tab, select the field delimiter for the data file, in this example Tab .

7. Select the Header tab.

8. Select the number of header lines to be skipped during the data load, in this example, 1 , and then click OK .
