Sure, you can achieve this by creating a UI Policy in ServiceNow. Here are the steps:
1. Navigate to System UI > UI Policies in ServiceNow.
2. Click on New to create a new UI Policy.
3. Fill in the necessary details like Name, Table (probably 'task' in your case), Active (true), and Order.
4. In the UI Policy Actions related list, click on New.
5. Fill in the necessary details like Name, Run scripts (true), and Script.
6. In the Script, you can write a script to set the default filter. Here is a sample script:
javascript
function onLoad() {
//Set the default filter for 'Assigned to me'
var assignedToMeFilter = "active=true^assigned_to=" + gs.getUserID();
g_list.setFilter(assignedToMeFilter);
//Set the default filter for 'Assigned to my group'
var assignedToMyGroupFilter = "active=true^assignment_group=" + gs.getUser().getRecord().getValue('group');
g_list.setFilter(assignedToMyGroupFilter);
}
7. Click on Submit to save the UI Policy.
Please note that this is a basic example and you might need to adjust the script according to your exact requirements. Also, the 'group' field might not exist on the sys_user record by default, so you might need to create it or use a different field that holds the user's group.
Remember, UI Policies run on the client-side, so they do not require a form refresh to take effect. They are also not recommended for data security as they can be bypassed by savvy users. If you need to enforce these filters for data security, consider using a Business Rule or ACL instead.
