How to make business rule message appear in portal form.

[Lucas Jesus]

I'm creating a business rule that when the registration is this week, it displays the message at the top of the requested service form, the message is "Attention: Pay attention, because the date of this service is this week!"
On the back-end it's working, everything is beautiful and perfect, but on the portal no message appears.

This is just an exercise for the company I work for.
Thanks!

Hello,

Please give more information as to how you've implemented this to include an example of the code and screenshot, if possible.

We can't really help you without you letting us know what you've tried, etc.

Not really sure how you're displaying a message at the top of the form via a business rule unless you're talking about some sort of post-update action or something.

Please mark reply as Helpful/Correct, if applicable. Thanks!

This message on a blue background must appear on the portal, in a ticket/record.

Either in this column on the right or on the left. It doesn't matter where.

This message in a fictional scenario, would be to alert the company's employees that the service requested by the customer is scheduled for this week. But employees would only have access to the portal, not the back-end. So I wanted to know how do I get the message to appear to the employee.
Again, this is just an exercise for the ServiceNow partner company where I work. I am in the process of learning the platform and asked for this in the exercise statement.
