How To Fix TO146 - Cancel role change: Objects exist in namespace &1

SAP Error Message - Details

• Message type: E = Error

• Message class: TO - Transport Organizer and Tools

• Message number: 146

• Message text: Cancel role change: Objects exist in namespace &1

What causes this issue?

You have changed the role of the namespace &V1&, although objects
already exist in it. Cancel the changes to the namespace role.
The role is changed from "Producer" to "Recipient" automatically when
the namespace is delivered. An automatic change of the role from
"Recipient" to "Producer" is not planned and contradicts the global
protection of namespaces.
Changing the role manually leads to inconsistencies, since the
namespace role determines actions when changing or creating objects of
the namespace:
In recipient namespaces you can only edit objects when making repairs,
You can carry out developments in producer namespaces, i.e. object
changes are made in corrections.
Since these two settings contradict each other within an SAP System, it
is not usually sensible to change the role of namespaces in which
objects have already been created.

System Response

Editing continues. You can correct your change afterwards.

How to fix this error?

Cancel the change you made to the role for the current namespace &V1&.
