6 1 Introduction This document provides instructions for creating a simple IBM TRIRIGA cross-tabulation (or cross-tab) report in Business Intelligence and Reporting Tools (BIRT). It also includes tips and an example that may be helpful for the report designer to create this type of report. For example, if you need a TRIRIGA report to show the sales total by year for each sales category using the data (see Sales Reporting Details below) it will look something like the Sample Sales Report (see further below). In TRIRIGA, this type of data can be presented nicely by a cross-tab report in BIRT. Figure 1: Sales Reporting Details Figure 2: Sample Sales Report 6

7 2 Prerequisites This document assumes that the reader has a basic understanding of the IBM TRIRIGA Application Platform and the fundamental concept that is required to operate the webbased IBM TRIRIGA system. The Eclipse - BIRT Report Designer must be installed. 3 Creating a cross-tab BIRT report Step 1: Export the starter report from the IBM TRIRIGA query in Report Manager. Figure 3: Export the starter report Step 2: In Eclipse - BIRT Report Designer, create a new Report Project and import the starter report into the project folder. Figure 4: Import the starter report 7

8 Step 3: Expand the Project Folder and then open the rptdesign file. Figure 5: Open the rptdesign file Step 4: Double-click the data set in Data Explorer. Figure 6: Double-click the data set Step 5: Select Output Columns, change the field type from Java Object to an appropriate type for each field. For example, change the data type to be Date for the "Date" defined field. However, keep the "Sales Total" field as Java Object. The reason is given later. Figure 7: Change the field type 8

9 Notes: All starter reports have all of the output columns that are modeled as Java Objects. Using Java Objects as the data types for IBM TRIRIGA data provides you with increased flexibility in development reports. However, unlike the regular table, which you can display the Java Objects columns on the report directly, the cross-tab report needs to have the data with correct data type before they can be used for Groups or Summaries in the data cube. Otherwise, the data cube cannot be created correctly, and it may show exceptions or errors when you run the cross-tab report. Step 6: In Data Explorer, right-click on Data Cubes, and then choose New Data Cube. Figure 8: Choose New Data Cube Step 7: Drag "Sales Category" field from Available Fields and drop it under the Groups (Dimensions). Figure 9: Drag and drop under Groups (Dimensions) 9

10 Step 8: Drag "Sales Date" field from Available Fields and drop it under the Groups (Dimensions). Different from "Sales Category", "Sales Date" is a Date type field, which you can group the dates by any of the time periods. In this example, group the date by year. Figure 10: Group the date by year Step 9: Drag the "Sales Total" field from Available Fields and drop it under the Summary Fields (Measures). Double-click the field, and select the function to be SUM. Figure 11: Drag and drop under Summary Fields (Measures) 10

11 Figure 12: Select the function to be SUM Notes: As mentioned earlier in step 5, you changed the field type from Java Object to an appropriate type for each field. However, the "Sales Total" is left as Java Object. The reason is that you must use this field as source to get the IBM TRIRIGA user-preferred format after you aggregate the numbers inside of BIRT. Before the field can be used for calculation, you must access its native SQL value by using the object's getnativevalue() method. For example: datasetrow["triitem trirepercentrentitem trisalestotalnu"].getnativevalue() Step 10: Expand the Data Cube to verify its contents. Figure 13: Expand the Data Cube 11

12 Step 11: Select Palette, drag a cross-tab element from the palette, and drop it to the report. Insert the data from the data cube into the cross tab. In this example, place the "Sales Category" into rows area, "Sales Year" into columns area and "Sales Total" into summarized area. Figure 14: Drag and drop a cross-tab element Step 12: Select Preview to view the report. Figure 15: Select Preview 12

13 Figure 16: View the report Notes: You may notice that some of the cells are blank and the numbers do not display in the appropriate format. If you would like to show zero for the null value, and also format those numbers in the IBM TRIRIGA user-preferred format, continue with the following steps. Step 13: Select the palette, drag a table element from the palette, and drop it to the report. Set the Number of columns to 1, and then select the data set. Figure 17: Set the columns and data set Step 14: Remove the header row and detail row from the table. Put the cross tab into the footer of that table. Figure 18: Put the cross tab into the footer 13

14 Step 15: Delete the summarized field, drag a Dynamic Text field from the palette, and drop it to the summarized area. Write the following code in the express builder to format the number in IBM TRIRIGA user-preferred format. Figure 19: Delete the summarized field Figure 20: Drag and drop a Dynamic Text field For example: TRIRIGA.formatNumber( data["triitem trirepercentrentitem trisalestotalnu_salescategory/triitem trirepercentrentitem trisalescategorycl_salesyear/year"], row._outer["triitem trirepercentrentitem trisalestotalnu"].getuom() ) Notes: The field that used for getuom() is from the outer table. 14

15 Step 16: Select Preview to view the report again. Now the report shows the number in the same format as you defined in IBM TRIRIGA.
