Oracle Essbase 9 Implementation Guide- P31 docx

Chapter 4 [ 135 ] Step 4: Setting the View to Data Load Fields As you recall, in the previous chapter we used the Rules File to update the database outline. In this chapter, we are using, but this time, we are using it for loading data into the Essbase database. Please select Data Load Field View in the Rules File. By default Data Load Field View is selected. To set the Data Load Field: 1. In EAS, open the Data Prep Editor. 2. Click on View and then select the checkbox Data Load Fields. Step 5: Setting the Data Source Properties As discussed in the previous chapter, the Data Source Properties are also the same where you can set the column delimiter as Tab delimited or Comma delimited. The input columns from a relational database are Tab delimited which is selected by default. To set the Data Source Properties: 1. In EAS, open the Data Prep Editor. 2. Click on Options and then click on Data Source Properties.

The rst tab is the Delimiter tab. 4. Select or create the appropriate data delimiter. Step 6: Updating the Data Load Settings With this load rule setting, you can tell Essbase how to load the new data into the Essbase database and also, if necessary, how to load the new data in relation to the data that already exists in the database. In some cases, you need to load on a day-to-day basis. If there are adjustments to the data, how you will handle them? In the rules le data load setting, you can tell Essbase how to load the data into the Essbase cube, dene the headers, ipping of the numeric signs, clear specic data combinations, add to existing values, subtract from existing values, and so on. Step 7: Setting the Data Load Values To set the Data Load Values: 1. In EAS, open the Data Prep Editor. 2. Click on Options and then click on the Data Load Setting. 3. The rst tab is the Data Load Values tab. 4. There are three things that can be achieved in this tab setting: Data values, Sign ip, and Global select/reject Boolean.

This will only overwrite the data included in the new feed. If there is an existing value that is not included in the new data, it will not be overwritten. Let us say you are building or rebuilding your Essbase cube everyday. On Monday, you loaded data into the database that shows revenue generated as $40,000 and when you load new data on Tuesday the total revenue generated to date as $60,000. So, when you loaded the new data into the Essbase cube, the revenue from Monday's data feed is overwritten by Tuesday's revenue data. By default, in Essbase, the setting is set to Overwrite existing values. • Add to existing values: Select this option if you want to add your data to the existing data. While this is a great feature, you must be very careful while using it. If you ever need to reload the same data, due to an interruption or some other issue, you need to restore the data to its original state before the rst instance of the load. Otherwise, you will add to the values again resulting in erroneous data. As in the example above, you are building data loads on a day-to-day basis. You have a TOTAL VEHICLES SOLD member in your database outline. The data load rules le you are using is set to Add to existing values. If the TOTAL VEHICLES SOLD member on Monday is 100 units and Tuesday's data shows 20 more units sold, when you load this data the TOTAL VEHICLES SOLD will get updated to 120 units (100 + 20) since you have set this data load rules setting to Add to existing values. • Subtract From existing values: Select this option if you want to subtract the new data values from the existing data values.

If there are 1,000 units in the TOTAL VEHICLES IN STOCK member and you sold 100 vehicles today, when you load the daily data the 100 sold units will be subtracted from the 1,000 units in the TOTAL VEHICLES IN STOCK member. This will leave 900 as the new value in the TOTAL VEHICLES IN STOCK member. Sign ip Flipping the numeric sign is one of the features of the Essbase data load that can be accomplished in the data load rule. Sometimes it is necessary for us to ip the numeric sign of a set of values as they are being loaded into the database. Consider that the basic prot calculation is Sales – Discounts = Profits. The data elements you receive from the corporate nance department are all in positive numbers. Sales and Costs are provided as positive numbers. Depending on how you have your database outline structured and to keep things simple (simple is good) for you to create a Prot member in your database outline, you would need it to have two children. One child would be Sales and other would be Costs. When you calculate the outline, the values would roll up correctly to a total Prot. Another way would be to just have a Prot member to load the data values to and use the Add to existing values setting so you would add a positive Sales value and a negative Costs value to the Prot member as the data is being loaded. The only drawback to this method is you would not have the component data handy and loaded into the database in the event there are issues or questions with the data. Debugging would also be more complicated as you would need to go back to the input data for any validations. There are two ways, during a data load to ip a numeric sign on a data value. They are as follows: 1. Flip the numeric sign value based on an outline member UDA. For instance, you can only ip the numeric sign on members that are tagged with the UDA of Costs in the database outline. As you can see in the previous screenshot, there is a UDA called NegSign. While we are doing the Dynamic Calc, we check the UDA, if UDA is NegSign, we can do a negation. This is just an example. 2. Arbitrarily ip the numeric sign on all data values in a particular column or eld by multiplying the number with a minus (-) sign.

To achieve this functionality you need to set all of the members that need to be cleared in Clear Data Combinations tab of the Data Load Settings. This can be an extremely valuable setting when loading data that may have holes in it. For example, you are loading data values for all months of a particular calendar year, but the new data load has no data values for the months of May and August, the result will be the old values mixing in with the newly loaded values. This happens because Essbase will only load or overwrite data values for specic values received in the data. If no new data is received for the months of May or August, the old data values will remain. To set the Clear Data Combinations: 1. In EAS, open the Data Prep Editor. 2. Click on Options and then click on the Data Load Setting. 3. Click on the second tab, Clear Data Combinations tab. In the Dimension list, double-click on the members you need to clear the data and they will appear in the Combinations to clear as shown here: If you are using Overwrite existing values, then Clear Data Combinations may not be necessary as every time you load the data the old data will be cleared for the values you receive. However, if you are using Add to existing values or Subtract from existing values, you may need to clear the data values prior to the very rst data load to this scenario just to make sure all of the data has been cleared.
