A Parameter is just like a variable, which is used to provide the input of a particular data. The variable, which we passed in the parameter field is called an argument. An ordered list of the parameter is same as the parameter, but its argument is called and is assigned to the corresponding parameter. With the parameters, we can generate the report in the Crystal Report, according to the requirement.

We can also use the LOVs in the parameter, which enters the prompt value. It’s also static or dynamic.
Cascading Parameters

Cascading Parameters are combining with the dependency. We can create many groups of parameters in a single report group.

Inherited Parameters

Crystal Report allows the Intertied Parameters because these can be used later in the report and created in a parameter field in field explorer. We can also delete these parameters in the report but we can’t edit these parameters. These parameters can only be edited, where they are created.

Parameter Data Types

In Crystal Report, parameter works like an object and generated in the formula workshop. It is used in both static and dynamic. We can also generate the list of parameter value, which is selected by the user.

We use parameter data type in Crystal Report. Some data type parameters are,
  • String
  • Number
  • Time
  • Date
  • DateTime
  • Member
  • Boolean
List of Values Types
  • Static value
    Static value type gives a normal list, which depends on the data in the report and access the report from Crystal Report.

  • Dynamic value
    Dynamic value type gives a dynamic list.

  • Universe value
    Universe value list is a list, which provides a list, which is generated and maintained in the universe.

Thus, we learnt the variable is used to provide the input.
