Oracle Essbase 9 Implementation Guide- P34 potx

Loading Data into Essbase [ 150 ] Oops! There is a warning message indicating there was an issue with some of the data and that some or all of the data did not load into your Essbase database. In order to debug the issue, you need to look into the error le generated by the data load process. As you can see in the previous screenshot, the member name ES440 is not found in the data base outline. This means this member does not exist in the database outline. Just to be sneaky, we removed the alias for the 4 X 4 PICKUP member from the outline on purpose to force this error. Essbase will attempt to load data into the database using the actual member names or aliases. You can even select a specic alias table to use. Anytime if you see the Member Not Found in database message, it means this member does not exist in the Essbase outline. Let us add the alias code ES440 back into the outline and rerun the data load. Hooray, we did it! As you can see in the following message, the data has successfully loaded into your Essbase database without any error messages: This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com Chapter 4 [ 151 ] Loading data using MaxL By now, you must be familiar with the MaxL scripting language and its statements. We used MaxL to update the Essbase outline in the previous chapter. As you know, there are three ways you can execute a MaxL script. First, using EAS and the MaxL editor, second, you can execute MaxL scripts from the Command Prompt, and third, MaxL scripts can be executed from shell commands within another program. Let's use the EAS and the MaxL editor to create a MaxL script and then execute the script to load data into the Essbase database. Steps to execute MaxL from the EAS editor: 1. Within EAS, Click on File|Editor | MaxL Script Editor. 2. The MaxL editor will open. 3. Import Database MaxL statement should be used to load data. Syntax for the Import Database MaxL statement: IMPORT DATABASE APPLICATION NAME.DATABASE NAME The various elds present in the MaxL statement are: • DATA: We need to say data since we are loading data into the database. • CONNECT AS <Database Username>: Please specify the user name here since we are loading the data from the relational database. • IDENTIFIED BY <Database password>: Species your database password. • USING <LOCAL SERVER NAME>: Location of the rules le. • RULES_FILE <RULE FILE NAME>: Name of the rule le like dSales. • ON ERROR WRITE TO <PATH FOR ERROR FILE>: Error le information. The Path for error le c:/book/dataload_chap4.err The complete MaxL statement with correct syntax: import database 'ESSCAR'.'ESSCAR' data connect as 'hypuser' identified by 'password' using server rules_file 'dSales' on error write to c:/book/dataload_chap4.err This material is copyright and is licensed for the sole use by Paul Corcorran on 5th July 2009 8601 ave. p #1, , lubbock, , 79423 Download at Boykma.Com Loading Data into Essbase [ 152 ] Move the above syntax into the MaxL editor, and execute the MaxL statement. The statement should run without any error messages being generated. The next screenshot shows that the data has loaded successfully into the Essbase cube using a MaxL script statement: Now that you have successfully loaded the base data into your Essbase database, we now need to calculate the data in order for the data to be rolled up in the hierarchies described in the database outline. Parent values need to be summed from children values. Derived values need to be calculated from the newly loaded data component values. All of this and more is performed using the Essbase calculation scripts, known simply as Calcs. Calcs will be discussed in much greater detail in the next chapter, but before we continue, let us quickly recap the differences between a Data Load and a Dimension Build. Data Load vs. Dimension Build First, an Essbase data load is very similar to an Essbase dimension build. Second, an Essbase data load is very different from an Essbase dimension build. How can we make a contradictory statement like that? This is Essbase, that's how! Remember, Essbase is an art, not a science.

This predened database outline contains all of the necessary data attributes to organize the data into a logical and recognizable format. Building dimensions in an Essbase database outline is the process of loading data as data attributes, instead of data values, into the database in the form of adding new dimension members to the database outline. The missing data attributes in the database outline that are contained in the data are added by the dimension build process so that the accompanying data values can be loaded and not rejected. Summary Wow, who knew Essbase was such an easy to use and versatile tool when it came to loading data and maintaining your outline? Let's see, we have covered the how and why of making your data Essbase-friendly. We have also learned what it means to make data Essbase-friendly and what you need to do to make it so. As if that wasn't enough, you've also learned all about what are referred to as data sources for Essbase. You now know that a data source can be merely data values you load into your Essbase database, based on a predened database outline and data attributes accompanying the data values. You have learned about the various types of data sources, how Essbase deals with them, and what you need to do to lter, manipulate, or cleanse them before use. After all of that, we took all what you've learned about data and data sources and applied it by creating your rst data load rules in Oracle Essbase. You then used that load rule to load some honest to goodness real data into your Esscar database. That was easy, wasn’t it? In the next chapter, we get into the handy dandy Essbase calculation script. This small tool is pretty much singularly responsible for the vast differences between Oracle Essbase and any typical relational database. Not only can you calculate data on the y, you create new data elements that are derived from component data elements that exist in the database, without loading large amounts of data if the results you want can be derived from the data already existing in your database.
