Selecting Case Table Parameters
Select parameters to include them in the case table:
1. Select one or more parameters to be included in the case table.
2. Specify whether the formulae are allowed in the case table:
Select the No Formulae Allowed radio button when the case table does not contain any formula.
Select the Parameter Allows Formulae radio button when the case table contains formulae.
* 
The No Formulae Allowed and Parameter Allows Formulae radio buttons are available only when the Enable Advanced Case Tables preference is enabled.
3. From the Parameter Allows Formulae drop-down list select the parameter allowing the formulae, when the Parameter Allows Formulae radio button is selected.
* 
Only parameters, that are supported for formulae and included in the case table, become available for selection. A parameter can be designated to allow formulae for a given case table.
4. Click OK.
