Simplified example; logical clustering of transactions that an invoice can be inlaid. Example update: we're going to scan invoices on the mailroom, set that transaction MR1M is needed, By the transaction from the single role to clear away the transaction is removed from all composite jobroles in which the task enter invoice is included. A separate (new) task with TRX MR1M would to the composite role of the employees of the mailroom should be added. This example illustrates how the objectives of transparency and maintainability are backed by a 2 layer authorization concept.
