HI @saptarshiamc ,
I trust you are doing great.

Create a Business Rule:

• Navigate to "System Definition" > "Business Rules" in the ServiceNow application.

• Click on "New" to create a new Business Rule.

• Provide a suitable name and description for the Business Rule.

• Set the "Table" field to "change_request" to target the change request table.

• In the "Advanced" section, enter the following code:

(function executeRule(current, previous /*null when async*/) {
    if (current.category == "ABC") {
        current.cmdb_ci = "cmdb_ci_server";
    } else {
        current.cmdb_ci = "";
    }
})(current, previous);

1. • Save the Business Rule.

2. Modify the Change Request form:

   • Navigate to "System Applications" > "Customize Form" in the ServiceNow application.

   • Search for and open the "Change Request" form.

   • Edit the form layout.

   • Locate the "Configuration item" field.

   • In the "Default Value" section of the field properties, enter the following code:

javascript:if(g_form.getValue('category') == 'ABC') { 'cmdb_ci_server'; } else { ''; }
