TW203 - Overview

• Message type: E = Error

• Message class: TW - R3trans - Messages

• Message number: 203

• Message text: Import of transport request &1 not allowed; you can lift this lock

What causes this issue?

The transport request cannot be imported because it originates in a
system without a link to the global object directory.

System Response

The import is rejected with return code 12.

How to fix this error?

You can use the ABAP program TR_ALLOW to release the import of this
transport request. You can then repeat the import. This program also
enables you to check the objects against the global object directory
for conflicts before the import. If any conflicts are found (for
example, an object with the same name already exists), we strongly
recommend that you do not import the object.
The objects are not recognized automatically by the global object
directory after you release and import them. This only happens once you
copy them to a normal transport request, which is released to the
configured transport routes.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
