This is relevant if you are customizing NetSuite SCM Mobile and seeking to enhance the user experience by displaying more meaningful error messages or customizing the error banners that appear during form validation in the mobile app. If you want to provide context-specific feedback to help users understand exactly what went wrong and how to resolve it, this trick can help.
Note: This applies only when validation is performed server-side. Client script validation is not covered in this article.
When I first customized SCM Mobile, I ran into the challenge of needing a way to show custom error messages during form validation. The mobile app didn’t offer an obvious method for adding these messages like the standard NetSuite Banners. Although Dynamic Texts were available, I found it more effective to use the native mobile banner.
After some discovery work and analyzing network activity in Developer Tools, I found that the app consistently received the same properties during validation from SCM's RESTlets. It looked like this:
The response includes two key properties: isValid and errorMessage.
The isValid property is a boolean (either true or false), indicating whether the validation passed or failed.
The errorMessage property contains the error message to be displayed when isValid is false.
This made it possible for me to create my own custom messages using that response format.
Since some validations require server-side processing, creating a custom RESTlet is a logical choice. You could include the same properties in the response, similar to this, to return a custom message:
In this scenario, when the user enters an invalid date and clicks the Enter Lot button, it triggers another custom action that calls a custom RESTlet for validation.
Below is an example of a RESTlet script that enables custom validation error banners in SCM Mobile
/**
* @NApiVersion 2.1
* @NScriptType Restlet
*/
define([], () => {
const post = (requestBody) => {
return {
isValid: false,
errorMessage: "The expiry date must be more than 30 days away"
}
}
return {post}
});
By leveraging RESTlets and using the existing validation handling of the app, you can display custom error messages in the Mobile utilizing the native error banners. This approach ensures users receive clear, actionable feedback during form validation, improving the overall experience.
