3784327 - Exception tasks do not appear in My Inbox when the assignment type is set to User in SAP Ariba Invoicing

I configured a Create Task action in the Configure Validation Rules application with Assignment Type set to User and assigned a specific individual user. When the validation rule fires and generates an exception (for example, a Goods Receipt mismatch), the task does not appear in My Inbox for the assigned user.

When I change the Assignment Type to User Group and assign a group instead, the exception task appears correctly in My Inbox for members of that group.

No error message is displayed; the task is simply absent from My Inbox.
