  Key Concepts: 
  A parameter field is a type of field in Crystal Reports that allows users to enter a value or select from a list of values when running a report. This value is then used to filter the data in the report. Parameter fields can be used to limit the data that is displayed in the report, or to prompt the user for input. 
  
  How to use it: 
  Parameter fields can be added to a report by selecting the “Insert” tab and then selecting “Parameter Field” from the drop-down menu. Once added, the parameter field can be configured by setting the data type, default value, and list of values. The parameter field can then be used in formulas or filters to limit the data that is displayed in the report. 
  
  Tips & Tricks: 
  When creating parameter fields, it is important to set an appropriate default value. This will ensure that the report displays meaningful data when it is first run. It is also important to set an appropriate list of values if the parameter field is used as a filter. This will ensure that only valid values are entered into the parameter field.
