How To Fix RU429 - Adhere to sequence when canceling time events

RU429 - Overview

• Message type: E = Error

• Message class: RU - Messages for order completion confirmation

• Message number: 429

• Message text: Adhere to sequence when canceling time events

What causes this issue?

A time event with the record type &V1& is to be cancelled.
In the chronological order or the time events entered a further time
event with record type &v2&, which was entered with the actual date
&v3& &v4&, follows the time event to be cancelled.
Due to this combination, a cancellation is not possible.
You are only able to cancel confirmed time events if time events that
go together such as 'processing start' and 'processing finish' are
cancelled in the right order. You must always cancel the finish time
event befor you can cancel the start time event.

How can this happen?

Example 1
The following time events were entered for an operation:
Processing start : 8:00am
Processing interruption: 9:00am
Processing start : 9:30am
Processing finish : 10:00am
In this case, both the 'Processing interruption at 9:00am' and the
'Processing finish at 10:00am' time events can be cancelled straight
away.
The 'Processing start at 9:30am' time event cannot be cancelled if the
'Processing finish at 10:00am' time event was cancelled first.
Example 2
The following time events were entered for an operation:
RESET N1
Processing start : 8:00am
Processing partial finish: 9:00am
Processing finish : 10:00am
In this case at first only the 'Processing finish time event at
10.00am' can be cancelled, then 'Processing partial finish at 9.00am',
and finally 'Processing start at 8.00am'
