Improving Performance of Your Scripts
To improve performance of your SmartScripts you can work with a BusComp user property called "DeactivateBCField". Setting this to "TRUE" or "Y" will deactivate all BusComp fields except those used in SmartScript Questions. By default, this field is not deactivated, leaving all BusComp fields active.
To make this change in Siebel Tools, identify the SmartScript Player applet being used in the application and then change the user property for the business component on which this applet is based.
