Hi @KM SN,

Looks like you are setting the value of a field in an after business rule for e.g.

current.assignment_group=<some group sys_id>;
current.assigned_to = '';

This works just fine if the script is used inside a before business rule as the fields get updated. However the same code doesn't work if you use it in the after business rule.

Here is the reason for this behaviour. According to ServiceNow documentation.

Before Business rule runs	After the user submits the form but before any action is taken on the record in the database.
After Business rule runs	After the user submits the form and after any action is taken on the record in the database.

Since the database operation already gets over before the control is passed to the after business rule. Hence changes made inside the after BR script do not get saved in database.

Solution: Use the following script to save your changes in after BR

current.assignment_group=<some group sys_id>;
current.assigned_to = '';
current.setWorkflow(false);
current.update()
