Except you can't scale it to multiple receivers.

This is how we wrote a system to process Payroll Clocks.
It is not complex and works like a charm without any complications.

Is there a way to rollback the receiving of a mesage from a dtaq in
case the processing of the message leads to an error. Like the
concept of acknowledgement on other messaging systems.

You can call QRCVDTAQ but not remove the message from the queue.

If there is an error, just leave the entry on the queue.
If there is no error then call QRCVDTAQ again and remove the entry.
