Adding Validations to Appian Objects

In Appian, it is crucial to implement robust validations for forms, fields, and processes to ensure accurate data, uphold business rules, and enhance user experience. Here’s the method to achieve this:

Form Validations:

• Client-Side Validations: These validations are performed on the client side (browser) before data is submitted to the Record or CDT.
• Model-Side Validations: These validations are performed on process Models So we Can Always Have null validation through the properly defined gateway. They are more secure as they cannot be bypassed by the client. They implemented using business rules or expressions in Appian.

Field Validations:

• You can add validations to individual fields within forms to ensure that the entered data meets specific criteria. For example, you can validate that a field is not empty, that it contains a valid email address, or that it falls within a certain range of values.
• Field validations can be configured using built-in functions provided by Appian or by writing custom expression rules.

Process Validations:

• In Appian processes, you can add validations at various points to ensure that the process progresses correctly and that data is valid.
• Gateways such as exclusive gateways (XOR) can be used to validate data based on conditions.
• You can also use expression rules within the process model to perform validations at different stages of the process.

Integration Validations:

• When integrating with external systems or APIs, it’s important to validate input and output data to ensure compatibility and prevent errors.
• You can validate data received from external sources before processing it within Appian, and vice versa.

Data Store Validations:

• When working with databases or other data stores, you can enforce data integrity constraints such as uniqueness, foreign key constraints, and data type validations.
• Appian supports integration with various databases, and you can utilize database constraints to enforce data validations.

Custom Validations:

• For complex business rules or validations specific to your application, you can implement custom validation logic using Appian’s expression language (SAIL) or integration with external validation services.

In summary, adding validations to Appian objects involves utilizing a combination of client-side and server-side techniques, leveraging built-in features, custom expressions, and integration with external systems to ensure data integrity and enforce business rules throughout the application.
