Event Management.Custom field Transform and Compose Alert mapping.

[Mark Wood]

Hello experts,

I have created one choice field whose name is a category with two choices default and remote on em_event.and another choice field I have made on em_alert whose name
is an alert category.
I know there is already a category field on the alert form. I am exploring custom field mapping that's is why I am doing this.
in my event rule, I have mapped the alert category and event category.
but the same category is not getting populated on the alert record. it's showing me "<<unknown>>".

when I did mapping for string type fields values ae getting populated on em_alert.

I have read below two articles and attached a screenshot of the mapping.
please guide me.
thank you.

Hello @Mark Wood,

Possible reasons

• The field type of the source and target fields are not compatible. For example, if the source field is a choice field and the target field is a string field, the mapping might fail. You can check the field type of your custom fields in the Dictionary module under System Definition
• The field value of the source field is not valid for the target field. For example, if the source field is a choice field with values “default” and “remote”, and the target field is also a choice field with different values, such as “low”, “medium”, and “high”, the mapping might fail. You can check the choice values of your custom fields in the Choice Lists module under System Definition.
• The event rule condition or script is not correct or complete. For example, if the event rule condition is too restrictive or the script has syntax errors, the mapping might fail. You can test your event rule condition and script using the Event Simulator module under Event Manag...

To resolve this issue, you can try the following steps:

• Verify that your custom fields have the same or compatible field type and choice values on both tables.
• Review your event rule condition and script and make sure they are correct and complete.
• Test your event rule using the Event Simulator and check if the alert category field is populated correctly on the em_alert table.

Hope this helps.

Kind Regards,
