3451562 - Approver of supplier invoice cannot receive approval notification email

Approver of supplier invoice cannot receive approval notification email although user has subscribed to the supplier invoice approval task.

SAP Business ByDesign

User has only checked box  'Approve <BO Sub Type> <Supplier Invoice ID> - <Supplier Name> - <Total Gross Value of the Supplier Invoice>' under Managing my area - Supplier invoicing from Home - Inbox - Subscribe to Task.

User must also check the box 'Approve <Cancellation Indicator text> <BO Sub Type> <Supplier Invoice ID> - <Supplier Name> - <Total Gross Value of the Supplier Invoice>', then the approval notification will be sent to the user email address.

This is expected system design.
