The Validate tab relates the to-be-evaluated properties and their corresponding validation settings in a row-column matrix structure. Complete this tab to define validation conditions for one or more properties.
Specify the properties in the first column (under the Property heading). Then for each property, use the fields and controls in the other columns to specify defined sets of validation conditions that the system applies to the property. By default, there is a set named Default Validation. Additional columns are displayed if input-qualified validation conditions are specified.
Best practice: Aim to use no more than fifty (50) rows and ten (10) columns on this tab. If you need to specify more than that, create another validate rule to use in the Additional Validation fields.
When the system runs the validate rule, it first evaluates the validation conditions defined for the first property in the list, then it evaluates the validation settings for the second property, and so on. When a property is found to be invalid, if no further validate actions are specified (for example, if Continue Validation is not selected in the condition details and nothing is specified for the Also Execute or Additional Validation fields), the system ends its evaluation.
Expanding and collapsing details
Use the Expand All and Collapse All buttons to show and hide the details of all of the specified conditions in all columns for each property.
To expand or collapse the details for an individual column, click the 
and 
icons at the top of the column.
Note: When you save the rule form, the expanded and collapsed states of the columns are saved. When you re-open the rule form, it reflects the last state.
When the details are collapsed and conditions are specified for a property, the column displays the number of specified conditions (for example, 2). If the conditions are disabled, the number is grayed out.
Input-qualified validation
You can optionally provide different sets of validation conditions to be applied depending on the value of an input property, a proposed work status, or a flow action.
For example, in a loan application, you might want to have different validation depending on the loan applicant's risk rating — if the rating is medium or high. Given an input property RiskRating that has Table Type of Local List, with values High Risk, Medium Risk, and Low Risk, in the validate rule form, you can define one set of validation conditions for High Risk and another set for Medium Risk:
You can use proposed work status as the qualifier for input-qualified validation. In this case, a flow action form specifies a Proposed Work Status value. In the validate rule, by specifying the Proposed Work Status on the Input tab, you can qualify sets of validation conditions according to work status values (such as Pending-Approval or Pending-Investigation). At run time, when the system runs the validation rule from the flow action, it evaluates the set of validation conditions that corresponds to the Proposed Work Status value from the flow action.
You can use a flow action as the qualifier. In the validate rule, by specifying the Flow Action Name on the Input tab, you can qualify sets of validation conditions according to the flow action. Select the ActionName key part of a flow action. This approach enables you to design a single rule that can be shared by multiple flow actions, each with its own set of conditions. For example, instead of designing a validation rule for each flow action in a screen flow, you can define the validation for the entire interaction in a single place making it easier to build, edit, and maintain.

Validation results
When executed, a validate rule adds messages to the clipboard page containing the properties that fail validation. This does not directly cause the messages to be presented to a user.
Note: You cannot use a validate rule to present a custom error message for the specific case of a user simply leaving a required field empty in an input form. In this case, the system presents a fixed message "This field may not be blank" to the user. (This is the case where the Validate tab has the Required checkbox selected for that particular property, no additional conditions to satisfy, and at runtime the user leaves the field corresponding to that property blank in the input form.) If the validate rule specifies additional conditions (for example, a condition that the input value must be greater than a particular number) and a custom error message, and the user leaves the field blank, the system presents both the standard message "This field may not be blank" and the custom error message (because the blank input also fails the additional specified conditions).

Fields and controls in the Default Validation column
The following fields and controls are available in the Default Validation column. Each property specified in the Property list has a corresponding Req and Conditions pair in the Default Validation column.
If using input-qualified validation, use the Default Validation column to define the set of your least restrictive conditions. For example, if your input-qualified validation sets are based on the values of an input property, the Default Validation set would specify conditions that you want applied to the properties regardless of the input property's value. Then, in the columns for each input property value, select Default Validation for the Also Execute field, so that the system applies the default conditions after applying the conditions for the particular property value.

Typically, you select At runtime, for a given to-be-validated property, the conditions specified in the applicable value-qualified column "win". For example, when:
At runtime, the system first looks to see if there is input-qualified validation when it applies this validation rule. If so, the system locates the value-qualified column that corresponds to the runtime value of the input property or proposed work status, and then evaluates the conditions in that column. If not all of the conditions in that column are satisfied (the property fails validation for that value-qualified column) and Continue Validation is specified, then the system looks at the Also Execute selection and evaluates that column. However, if the property has satisfied all of its corresponding conditions in the first evaluated column, then it is considered to be valid and the subsequent column is not evaluated. |
