170 Configure the Data Validation Transformation Chapter 10 10 Click and drag the table CHECKING_TRANS_VALID into the target drop zone. The table appears as the target in the new job, along with a Loader transformation, as shown in the following display. Display 10.18 Sources and Targets in the Data Validation Job The job now contains a complete process flow diagram. The next task is to configure the Data Validation transformation. Configure the Data Validation Transformation The example job has now been populated with a source, a target, and some transformations. Follow these steps to configure the Data Validation transformation: 1 In the Process Designer window, double-click the Data Validation transformation to display the transformation’s properties window. To use a lookup table to validate values, click the Invalid Values tab. 2 On the Invalid Values tab, click New to display the Invalid Values window. Click Column Name, display the columns of the CHECKING_TRANS table, and select the column CHKING_TRANS_METHOD_CD. Example Process Flows Configure the Data Validation Transformation 171 3 Click the browse button to the right of the Lookup Table field and select CHECKING_TRANS_LOOKUP. Then click OK to return to the Data Validation properties window. Display 10.19 Invalid Values Window 4 To specify the name of the error table, click the Options tab. In the Error Table row, enter the SAS libref and filename (rather than the metadata names) of the error table, such as ORGOLD.CHECKING_TRANS_ERROR. Click Apply to store your input. 5 To replace missing values, click the Missing Values tab, then click New. In the Missing Values window, select the column CHKING_TRANS_CHANNEL_CD. In the Action if missing field, select Change value to. In the New Value field, type "??", with quotation marks. Click OK to return to the properties window. Display 10.20 Missing Values Window 6 To configure the detection of duplicate values, click the Duplicate Values tab. Click New to display the Duplicate Values window. In the Available Columns list, select CHKING_TRANS_ID, then click the arrow to move that column name into the Selected Columns list. 172 Run the Job and Check the Log Chapter 10 7 To specify that the job is to be aborted if a duplicate transaction ID is found, select Abort Job in the Action if duplicates field. Display 10.21 The Duplicate Values Window 8 In the properties window, click OK to store your input and close the window. The transformation is now fully configured and the job is ready to run. The next step is to submit the job and check the SAS log. Run the Job and Check the Log After the metadata for a job is complete, you submit the job for execution in order to load data into the target. 1 With the job displayed in the Process Designer window, select Process Submit from the menu bar. SAS Data Integration Studio generates code for the job and submits the code to a SAS application server. The server executes the code. 2 If a pop-up error message appears, or if you want to look at the log for the completed job, click the Log tab in the Process Designer window. 3 On the Log tab, scroll through the SAS log information that was generated during the execution of the job. The code that was executed for the job is available in the Source Code tab. 4 If you find errors in the source code, correct the properties windows of the affected transformations. 5 Correct the metadata and resubmit the job until there are no more errors. 6 After the job runs without error, save the job. Select File Save from the menu bar. The next task is to verify that the job created the correct output. Example Process Flows Verify Job Outputs 173 Verify Job Outputs After the job runs without error and has been saved, open the target table CHECKING_TRANS_VALID and the error table CHECKING_TRANS_ERROR to check the results. 1 To view the data in CHECKING_TRANS_VALID, right-click the table in the Project tree or in the Process Designer and select View Data . 2 To compare the target to the source, repeat the previous step for the source table CHECKING_TRANS. As shown in the following display, three missing source values have received the value ?? in the target in place of the former missing values. Display 10.22 Contents of the Target Table CHECKING_TRANS_VALID 3 The source table contains three invalid values. These values were correctly identified as invalid because they did not appear in the lookup table CHECKING_TRANS_LOOKUP. The following display confirms that three invalid values were written into the error table. A careful look at the target table in the preceding display shows that the source rows were not written into the target. These errors are also noted in the log. Display 10.23 Contents of CHECKING_TRANS_ERROR 4 The data validation job was configured to abort if a duplicate value was found in the CHKING_TRANS_ID column. The source contained no duplicate values in that column, so the job ran to completion. 174 Example: Using a Generated Transformation in a Job Chapter 10 Example: Using a Generated Transformation in a Job Preparation Suppose that you need to perform a special task with a data set, and none of the standard transformations in the SAS Data Integration Studio Process Library support this task. An administrator can use the Transformation Generator wizard to create a custom transformation and make it available in the Process Library. The generated transformation can then be used in any SAS Data Integration Studio job. For example, suppose that you needed to create a report that displays hitting statistics for baseball teams. The following display shows the kind of output that is desired. Display 10.24 Tigers Hitting Statistics 2002 Report An administrator could use the Transformation Generator wizard to create a transformation that reads an input table with a certain column structure, enables you to specify certain options, calculates hitting statistics, and displays the result to the Output tab in the Process Designer window. SAS Data Integration Studio users could then use this transformation in any job. Assume that the following preparations have been made: An administrator has created the generated transformation (PrintHittingStats), and this transformation is available in the Process Library. For more information about creating generated transformations, see “Maintaining Generated Transformations” on page 75. The input to the PrintHittingStats transformation is a table that contains batting statistics for a baseball team. The columns in the source table are assumed to be similar to the columns shown in the following display. Display 10.25 Contents of TigersHitting2002 Table . Designer window, select Process Submit from the menu bar. SAS Data Integration Studio generates code for the job and submits the code to a SAS application server. The server executes the code. 2.
