SAP Error Message - Details

• Message type: E = Error

• Message class: TR - Change and Transport System

• Message number: 285

• Message text: &1 &2 &3 is not a valid key for reservations

What causes this issue?

You have chosen the key &V1& &V2& &V3& for your reservation.
This key is not allowed for the following reasons:
It contains an invalid object ID. (The help on the input fields
provides information on all object IDs defined.)
The key does not correspond to object-type or editor-specific naming
conventions, or refers to an object type that does not have to have an
object directory entry (does not have to be registered in the global
object directory), or is not transportable.
The possible reasons are so diverse that they cannot all be listed and
explained here. However, you can find out why the reservation was
rejected in the following way:
Go to the editor for the object type for which you want to make a
reservation.
Create an object with the appropriate naming convention. If the naming
convention is not allowed, a specific error message is displayed here.
If it is an object requiring an object directory entry, the "Create
Object Directory Entry" dialog box is displayed when you save. It
contains the correct object ID, which you must also use for the
reservation.
