IEG requires correctly formatted data be used in certain parameters. As such AppScan must be 'trained' to use the application being tested. Select 'Multi-Step Operations' in the view selection pane. Click the record button. This will cause the AppScan browser to be displayed and it will attempt to open the URL specified on the 'URL and Servers' page of the Configuration Wizard. You should then navigate through the application as required, entering relevant data. AppScan will record the values entered and use these values for each test that it runs later. Once you have finished, simply close the browser. The Scan configuration dialog will be updated with the sequence that has just been recorded. Check the 'Enable playback of this sequence' checkbox and uncheck the 'Allow play optimization' checkbox.
Take note of all the sequence steps that contain Screening.do. You will have to turn these sequence steps into regular expressions and add them as exception paths to the exclude path options of AppScan. AppScan can easily be thrown out of sync when it comes to recorded operations, so you have to ensure that AppScan will ignore the wrong path and keep to the recorded script when running its tests. This is achieved by telling AppScan to ignore all sequence steps containing screening.do, except those that you specify in regular expressions. Take note of each __u=x value found in the list of sequence steps.
