RU456 - Overview

• Message type: E = Error

• Message class: RU - Messages for order completion confirmation

• Message number: 456

• Message text: Service & cannot be created manually

What causes this issue?

The data &V2& &V3& was created for the work &V1&.
The definition of the standard value key in the work center determines
that the work &V1& should be given the duration that is generated by
the pair formation (start/finish) of time events.
An additional manual calculation of work cannot then take place.

How to fix this error?

With time event confirmations you may only create work for standard
values to which no record class group (setup/processing/teardown) is
assigned in the definition of the standard value key.
Proceed as follows:
First check which standard value key is maintained in the work center.
<DS:TRAN.CR03>Execute function</>
Check whether a record class group is assigned in the standard value
definition.
<DS:SIMG.SIMG_CFMENUOLPSOP19>Execute function</>
