What causes this issue?

The transaction which executed the CATT procedure has been cancelled.

System Response

The user has cancelled the transaction in foreground processing with
the OK Code /n. This cancellation affects the entire execution which
was called via the function module CAT_START, not only the current
procedure as in /bn. You can go to the log display despite the
cancellation.
&WHAT_TO_DO& Use the OK-Code /bn to end the current foreground
transaction if you do not want to cancel the execution as well.
