Flash messages, also known as popup or toast messages, are used for communication with users and to inform them of important changes or errors that have occurred while they interacted with record form.

To set up a new flash message that is not in the "out-of-the-box" installation, you need to:

1. Create a source message.
2. Create message translations.
3. Select the system element that the user needs to interact with in order to trigger the flash message and configure the logic for it.

Create a source message

All flash message texts are stored in the Source Messages (source_message) table.

To create a new message, complete the following steps: 

1. Navigate to System Localization → Source Messages.
2. Click New and fill in the Message field.
3. Click Save or Save and exit.

You can also add translations of this message to any language. See more in the Localization and Multi-Language Support article.

Configure a business rule

To display a plain text message when a business rule is executed, configure the following parameters in the business rule record:

1. On the Action tab, select the Add message checkbox.
2. Enter the Message text from the Source Messages table to have it localized.

If you need to add variables or dynamic links to other records in the message text, configure a script with the Advanced settings. You can specify the selection of the appropriate translation based on the user's locale in the script. 

See the Business Rules article to learn more.  

Configure a script

To add a flash message with a script, open the form of a record to which the message should be connected and find the Script field. You can use variables, dynamic links and translations in the flash messages.

The list of methods that can be used in the business rule to add a message:

• s_form.addErrorMessage(message)
• s_form.addInfoMessage(message, durationMilliseconds)
• s_form.addSuccessMessage(message, durationMilliseconds)

• s_form.addWarningMessage(message, durationMilliseconds)

• ss.addInfoMessage(message, params)
• ss.addErrorMessage(message, params)
• ss.addSuccessMessage(message, params)

(function executeRule(current, previous = null /*not null only when action is update*/) {
const iaStats = new SimpleRecord('instance_activity_stats');
iaStats.get('ci_instance', current.sys_id);
if(iaStats.sys_id){
  iaStats.active = false;
  iaStats.update();
  ss.addInfoMessage(IAStats <a href="/record/instance_activity_stats/${iaStats.sys_id}" target="_blank"><span style="color: #0050C8;">${iaStats.getDisplayValue()}</span></a> deactivated.)
}
})(current, previous);

(function executeRule(current, previous = null /*not null only when action is update*/) {
  const message = new SimpleMessage();
  const localizedMessage = message.getMessage('Inherits property has been activated for global UI action');
  ss.addInfoMessage(localizedMessage);
})(current, previous);
